Verisart is currently upgrading is is seeking a hands on Senior Golang Engineer who can work with our technical stack as we migrate from a tightly coupled backend and front end to using React/Redux.
The successful candidate will have strong web app and RESTfull API experience and will be able to support our in-house development team and can start immediately. Knowledge of micro services is also helpful.
The role would involve setting up the API framework as well as any authentication (OAuth2.0) and validation middleware. Routes would then need to be implemented and integrated. Role would also involve supporting any extra code requirements of the development team inside the scope of the API project.
The work will be carried out as part of a small team, based in London (Mayfair). Competitive rates offered, as well as flexible working hours although the position is full time and on site and the successful candidate must be available at least 4 days per week at our office in London.
In general Verisart seeks engineers interested in applying cryptography at real world problems. Our problem lies within the art market as we address the problem of proving provenance for artworks and building evidence based certificates of authenticity. We recognize that cryptography is not a magic bullet. We want to use it intelligently to provide evidence where possible for people to interpret, like the web of trust. We’re looking for people who understand how to apply cryptography to problems. While understanding the mathematical backgrounds to cryptography is great, it’s not essential if you understand how the cryptographic primitives like hashing and message signing work together to solve real problems. We value passion and hard work when tackling challenges and above all else although an interest in arts and collectibles is helpful.
Skills & requirements Requirements
Computer science degree or similar (preferred but not necessary). Git. High level experience such as C++, Golang, Rust, Java, Python. Bitcoin experience is an asset.

Our mission is to give every person on the planet fast and affordable internet. We remove traditional internet infrastructure costs by developing technology which allows any device to be used as a cloud server. Using this tech, we will build a global distributed cloud platform. We are working at the forefront of distributed systems, peer-to-peer networking, and cloud systems.
Flare’s first product is a peer-to-peer CDN, designed to be faster and cheaper than incumbents. We are looking for someone to help us tackle the scalability challenges around our product. You will help us design and build out our caching, messaging, and routing systems to work across millions of nodes. You will have significant input and control over the architecture of these systems, to help us ensure that they are scalable, reliable, and fast.
We raised a £1.1m seed round earlier this year, and are backed by some of the original investors of Protocol Labs, Transferwise, and Zoopla. We have already partnered with industry heavyweights like the Guardian Media Group (one of the largest media platforms in the world), and our advisory board includes the ex-CEO of BitTorrent, ex-CTO of Shazam, and one of Akamai’s founding architects.
You will be a core team member in a fast-moving startup, working alongside talented engineers to build and ship a product that will be used by millions. You will be one of the first employees at Flare, and you will have direct input over the architecture and design of Flare’s systems. It is an unparalleled opportunity to grow and learn in a startup environment, and have direct impact on Flare’s direction.
We are looking for someone who has built and deployed performant and distributed systems at scale (preferably in Golang). We expect that you have experience working with the major cloud providers (AWS/GCP), ideally in high-load systems. You should be familiar with CDN architectures (caches, origin servers, proxies, etc), the networking stack, and the infrastructure of the internet.

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.
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
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.
