Job Description

About Raven Black

What turns a minor skirmish into a major war? How does a natural disaster become a humanitarian crisis? Often, its poor decision-making caused by incomplete or inaccurate information that causes miscalculations, missed opportunities, and accidental escalations. That lack of knowledge and the uncertainty it causes is called “the fog of war.”

Raven Black’s command and control software platform does precisely that by combining scalable data infrastructure, machine learning, and visualization tools. Its purpose is to lift the fog. Raven Black has raised $4.5M from top tier VCs, including Accel, and has generated over $3.9M in revenue.

What You’ll Do

Our platform ties together dozens of data sources, any one of which could be the critical piece of the puzzle a decision-maker needs. Your job will be to thread new sources through our platform, from ingestion through parsing, ETL, ML/AI models, and visualization. In the process, you’ll learn everything about how the system works and contribute to our core infrastructure development. Each time you succeed, the fog of uncertainty will retreat that much further.

You may be a great fit if you…

  • Have at least 2 years of professional software development experience and at least 6 months working in Go
  • Enjoy and have experience designing, building, and managing data processing/storage infrastructure
  • Hold yourself and others to a high bar when working with production systems
  • Enjoy taking projects involving a wide variety of technologies to successful completion
  • Write high-quality code and can think in terms of systems and services. We work mostly in Go with some Python, but languages can be learned. We care much more about your general engineering skills than your knowledge of a particular language or framework.
  • Thrive in a collaborative environment with stakeholders and subject matter experts from a variety of disciplines

1 year ago

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.

  • 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 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!

Backend Go Developer with Geckoboard
London, United Kingdom£40k - £61k
1 year ago

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.

Senior Software Engineer with Fat Llama
London, United Kingdom£70K – £100K
1 year ago

Job Description

What if owning things was no longer important? What if expensive, niche items could be available to you in seconds? And what if you could generate an extra income from your own belongings? At Fat Llama, we’re already bringing about that future. We believe that one day, owning those things we only occasionally need will be as ridiculous as buying a house every time you want to go on holiday.

Our users enjoy on-demand access to anything from high-end cameras to drones to campervans. As a result, they’re doing, creating and achieving incredible things every day. Income from rentals is changing the lives of many of our lenders, too - whether it’s paying their rent or allowing them to drop corporate jobs and focus on passion projects.

The herd’s growing fast, too. Last year we went through Y Combinator and recently announced a $10M raise from amazing investors to superpower our growth and focus on American growth.

Our Technology

Technology is at the heart of everything we do at Fat Llama, allowing us to solve a problem that has never been solved before. Our whole team gets a say in the product & tech roadmap, and our engineering team takes pride in writing, testing and deploying new features on a daily basis.

As an engineer at Fat Llama, you’ll be responsible for crafting, building and running the software which underpins our marketplace. We’re looking for somebody that can deliver solid engineering whilst moving at the same speed as our constantly growing business. You should also be excited about helping shape the direction and culture of our engineering team going forward.

Are you excited by the prospect of learning new technologies? In a rapidly changing and growing startup, you’ll be required to wear many different hats. Whether it be designing scalable systems, building tools to help our Operations team keep the business running, or slicing and dicing data for our analytics dashboards, you should welcome the challenge. You should thrive in a constantly changing environment and enjoy learning new things at a fast pace.

Our team takes pride in owning our work truly end-to-end. We’re looking for people who can plan, experiment, build, test, deploy, measure and iterate before calling it done. As a small team, we try and build on the shoulders of giants, which means that you’ll often find us working with the latest and greatest technologies.

You might be a good fit for the role if you:

  • Want to work in a team that values teamwork, learning and collaboration.
  • Love writing clean, elegant code that other people can read.
  • Have a deep understanding of at least two programming languages or paradigms.
  • Have experience mentoring and teaching other engineers.
  • Have led engineering projects from conception to delivery
  • Have expertise in designing and building web services or APIs.
  • Take pride in your fastidious approach to testing your code.
  • Have a real passion for user experience. Every. Llama. Counts.

We would be thrilled if you also had:

  • Experience building distributed systems or microservices.
  • Android, iOS or React Native work under your belt.
  • A deep understanding of JavaScript or Golang.
  • Experience working with and launching cloud based services.

If you don’t feel like you fit all of these areas, don’t worry. We are dedicated to the development of our team. Whether you’re a computer science graduate, an artist or a bricklayer, as long as you’re also a programmer, we’d love to hear from you.

Please note that the package for this role will include equity.

Applicants with less experience may want to consider applying for our software engineer role.

We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, colour, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.

Backend Engineer with Cuvva
London, United Kingdom£60K – £75K
1 year ago

Job Description

Core platform

When we refer to the “core platform”, we mean the services which underpin the processes of all insurance activities on our system.

For example, we expect one of these to be the “policy service”, which might be responsible for ensuring compliant issuance of policies, coordinating mid-term adjustments, preventing overlapping policies (double insurance), etc.

Other services could include user authentication, risk & pricing calculation, handling the process of modifying user data in-line with any mid-term adjustment requirements.

All services we consider to be part of the core platform will have strict requirements around stability, data integrity and transactional safety. All functionality must fail safely and explicitly, for example using 2-phase commit processes or other similar techniques. This will also require a reasonable level of testing to validate this safety.

Requirements

The perfect addition to our team will have:

  • a fiercely independent and self-driven approach
  • 5+ years’ commercial experience working on back-end systems at high-scale startups
  • at least a year of commercial experience working with Go
  • strong knowledge of security practices, ideally with a slightly grey-hat background
  • a working knowledge of the entire web stack - from how DNS lookups are transmitted, to how browsers prioritize CSS rules
  • awareness of compliance and financial regulation

We are a small team so it is important that the successful candidate is not only technically highly competent, but also a great cultural fit!


Perks & Benefits

As well as a competitive salary (£60-75k, dependent on experience) and equity based remuneration, benefits of working at Cuvva include working in our new offices in Shoreditch and of course significant savings on your car insurance.
