Golang Tyk Technologies Ltd Jobs in United Kingdom

Job Description

Distributed Systems Engineer - to help us build a public, decentralised, blockchain-backed legal agreements network

London
£40,000 - £80,000 plus options (ESOP).

Relocation package available for the right candidate. This role could also be based in our Edinburgh office.

Candidates currently based outside of London or Edinburgh must indicate their preferred location and willingness to relocate in their cover letter.

We are looking for kind, talented software engineers to help us make smart iterations on our legal agreements network as we deploy successive test networks.

Monax were pioneers of permissioned blockchains and smart contracts and we are building our Agreements Network to allow new and more efficient forms of legal transacting.

Exploiting the benefits of various decentralised, distributed, and masterless technologies - chiefly Hyperledger Burrow, which Monax built from scratch and still maintains based on the Tendermint consensus engine.

You will have the chance to work on a system that has distributed consensus and validation in a low trust environment at its heart and offers very interesting challenges, these could be:

• Working with multiple clusters of nodes, most of which are not under your control to handle semi-automated network upgrades and governance votes. How do you upgrade a network you do not control?
• Using cryptographic primitives like Verifiable Random Functions to orchestrate churn amongst network validators
• Build package manager and compiler integrations for deploying and testing smart contracts
• Implement low-level virtual machine instructions and improvements to our Ethereum Virtual Machine implementation

Working with our CTO on our Node Distribution Team you can expect to quickly own significant parts of our stack, and make decisions that will affect the company’s future viability in a fast-moving space (public permissioned consensus networks). You would also work closely with our Product Team who are responsible for building the foundational smart contracts, the business process modelling engine that drives the Agreements Network and also our particular front end (the network is open to extension by any of our co-founders however).

Your role will give you the chance to work across all teams in the business and it will also give you the opportunity to leave your mark in a growing industry, where you need to evaluate existing best practices and apply them to new technological paradigms and new programming languages. Navigating between the hype, the detractors and the zealots we believe there is real value in our approach and we intend to prove it.

You will join a business building a genuinely novel system, that in part intends to create an entirely new market by enabling legal products that challenge existing legal services.

This role would suit a talented software engineer, with solid technical skills in and a minimum of 3-4 years of software development experience. We are also open to engineers who can bring significantly more experience to the role. If you are a good match for Monax, we are willing to create a role that suits you.

Who do we need? Someone who has:

• Go experience or the ability to pick it up in a few weeks
• Kubernetes experience or the ability to pick it up in a few weeks
• A degree-level qualification in a numerate discipline or equivalent evidence of analytic and reasoning skills and theoretical thinking
• A good knowledge of algorithms and data structures
• A hacker mentality towards making things work
• An ability for long form design work ‘on pencil and paper’
• An ineffable marmot-ness

It is crucial that you are able to take part in forceful yet respectful technical discussions with colleagues and that you are able to change your mind about something if required, and also are able to change other’s minds.

Real things you might work on:

• Build a Kubernetes operator for Hyperledger Burrow
• Devise a way to compress/normalise data in our merkle tree to control our long-term storage usage
• Implement an atomic swap with public Ethereum to represent value on our chain
• Write optimised native (Go) functions, callable from evm, to implement graph traversal over our business processes
• Build fee allocation and distribution models that help maintain our network and provide the correct incentives

What can Monax offer you?

Extremely marketable blockchain and cryptocurrency skills.
The chance to make blockchain systems live up to their hype by making them highly operable, our network will be operated peer-to-peer by many parties and this needs to be as painless as possible.
Experience in blending distributed, decentralised, and centralised systems. To spend time working on something foundational at the level of a network architecture.
The chance to spend time thinking ‘around the software’; about law, economics, and game theory.
You will have a high level of autonomy. The business has just enough hierarchy, consensus and individual project responsibility (c.f. design-by-committee) favoured over diktats.
Flexible working - the successful candidate will be based in our London or Edinburgh work space primarily, but there is scope for flexible working and choosing your own hours and place of work when established.

Relocation assistance is available for the right candidate.

Who will you be working with?

Around fifteen people in our passionate cross functional team, including time with:

• Our CTO in London, who would be your primary daily contact
• Our CPO in New York, with whom you’ll liaise with to ensure the distribution platform and product stack work harmoniously.
• Product Team members currently building the application stack.
• Our Legal Engineers in New York providing crucial context to how legal products on the platform will be used
• Our CEO in Edinburgh for just about anything else...

Job Description

Resin.io provides a software platform that helps developers build, deploy and manage code on connected devices. We brought Docker to embedded GNU/Linux devices in 2013 and have been building our IoT toolkit ever since. We also maintain a variety of successful open source projects including Etcher, Balena, and resinOS, and made contributions to high-exposure projects such as Docker, Electron, and AppImage.

Our technology is open, standards-based, and proven in production across a wide range of scenarios from drones, 3D printers, point-of-sale devices, tidal turbines, skyscrapers and more. Our investors include DFJ, Aspect Ventures, GE, and Ericsson.

Resin is a highly distributed, remote-friendly company with a pretty much flat hierarchy. Our organization is adaptive, getting feedback signals from our users and systems. Right now we organize ourselves by projects, which allow us to build complex features and solve big problems, while staying mutable. As a distributed group, we rely on clear communication and the rule of "assume positive intent" to help us work together across time zones, cultures and first languages. Our base of operations is nominally London, though really we are living all over the world: from Barcelona to Bulgaria, Argentina to Vietnam, and many more.

On being a Backend Engineer at resin.io

We maintain a service infrastructure for IoT devices, and this is where we have quite a bit of our engineering talent. You will be actively working on one or more of these core components, fixing bugs, solving complex technical problems, and implementing user-facing features across the resin.io stack. While resin.io focuses on IoT, the majority of our engineers don't require embedded programming expertise.

People who are successful engineers are well-rounded generalists and great communicators. They are eager to take responsibility for a project, and are able to make good decisions about the project because they have the context of what's important.

We don't require engineers to be already familiar with the technologies we use. We are happy to invest in people that showcase a strong understanding of the challenges of building secure distributed systems.

Responsibilities

• Actively invest back in our own technology, libraries, and frameworks
• Understand security best practices and strive to apply them in your work
• Be highly motivated to produce great code
• Evaluate customer requirements and other inputs to determine the scope and timing of new functionality
• Design, architect, and own the execution of your projects
• Ensure the architecture of our distributed system remains cohesive
• Collaborate, brainstorm, and coordinate work with other resineers
• Understand the high-level goals, and thus know how to prioritize your work
• Challenge orthodoxy when that will help the product evolve
• Work efficiently with a certain amount of ambiguity in the tasks you're executing

REQUIREMENTS

Need to have:

• Desire to make yourself and others more effective. You'd be bothered by an inefficient process
• Good understanding of software engineering practices and how to apply them
• Excellent written communication skills, and fluency in English
• Self-discipline to take on a project and push it to completion without too much management. You also know when to ask for help
• Strong problem-solving abilities. You know how to split a complex problem into incremental pieces
• Basic front-end development skills

Nice to have:

• A sample of your work (URL or attached sample)
• Contributions to OSS projects (please include a URL)
• Having worked remotely before
• Experience with Resin.io as a user
• Experience with embedded GNU/Linux, anything ranging from personal projects with a Raspberry Pi to commercial or industrial scenarios with custom devices
• Experience with React, Node.js, Docker, PostgreSQL, or Kubernetes
• Experience with embedded development and microprocessors
• Experience with the Electron framework and cross-platform development
• Experience leading software projects in the open source world

Make sure to let us know if any of these items apply to you!

Perks & Benefits

• Work with an extremely talented, diverse team

Job Description

At Geckoboard we help businesses use their data to align their teams on the metrics that matter most to them. We’ve been busy reimagining the way our customers get their data in Geckoboard and have a lot of interesting and creative work to do to shape their experiences. Right now, we’re looking for curious problem solvers to help us on this journey.

What are we working on?

We've completely rebuilt how data gets into Geckoboard from third-party APIs, thanks to a query planner that's written entirely in Go. Our query planner takes in the metrics that a customer would like to track, and produces a plan for how to fetch and transform those metrics from a third-party JSON API such as Zendesk, Intercom, Google Analytics, etc.

We’re now working on extending this platform and building various microservices for tracking our customers' rate limits and scheduling metric refreshes in the most efficient way possible. We’re also creating a caching engine that ensures we don't waste precious API calls on data that we know hasn't changed since last time.

The team are also in the middle of splitting up our existing REST APIs into gRPC microservices with segregated data stores. Which is a huge opportunity for us to rethink some of the fundamental assumptions about Geckoboard's data model and how we can re-architect our systems for greater reliability and to enable us to ship with more confidence.

We don’t expect you’ll have worked on all of these kinds of projects before, but if they take your fancy and you’re excited about working on distributed systems and database technologies at scale, we’d love to hear from you.

As one of our Backend Go Developers:

• You’ll be writing in Golang on a day-to-day basis.
• You will help architect, design, and build Geckoboard’s data pipeline.
• You’ll maintain and optimise our existing infrastructure and services.
• You will get involved in the prioritising and evaluation of our work.
• You’ll pair with team members and get involved in code reviews.

Joining us in our London office, you’ll be working alongside a growing team of empowered engineers, with a focus on building a high quality product our customers love, work life balance and personal development.

Keen to hear a bit more? Carlos, one of our Backend Go Developers has shared a little about what it's like working with the team, what an average day looks like and more in an interview on our Blog: https://medium.com/geckoboard-under-the-hood/working-at-geckoboard-as-a-go-developer-e73855bd0dd8

The Geckoboard Story

Thousands of businesses use Geckoboard to build live TV Dashboards that focus teams on what matters. We take the complexity out of connecting data and make it simple for anyone to understand key metrics at a glance. We have pre-built integrations with 60+ tools including Google Analytics, Salesforce, Zendesk, Intercom and Google Sheets and our customers include Marketo, Slack, and Skyscanner.

In our mission to make data useful, our growing team of 40+ is headquartered in London and span across eight time zones - from Mumbai to London, San Francisco to Hawaii and more. We're always looking for people with diverse backgrounds who bring unique perspectives and skills to join our team and in return we constantly strive to ensure that we offer the most encouraging, inclusive, and efficient environment possible.

We don't just pay lip service to work-life balance, we actively and strongly encourage it. Flexible working hours and the ability to regularly work from home lets you work in a way that fits you and your family. We see our contractual obligation to offer 25 days of paid holiday as a minimum for everyone in the organisation, not a limit.

We actively contribute to professional development, courses, conferences, and books. Our Engineering & Product team also run fortnightly "Innovation Wednesdays", where everyone has complete freedom to work on anything that interests them, from contributing to open source, to learning a new skill, or improving our internal tools and processes.

And, don’t take our word for it, see what the team say about the projects they work on: https://medium.com/geckoboard-under-the-hood and their experience of working with us on Glassdoor: https://www.glassdoor.co.uk/Reviews/Geckoboard-Reviews-E878996.htm.
