Backend Engineer with Monzo
London, United Kingdom£40k - £100k
3 months ago

Job Description

At Monzo we’re aiming to build the best current account in the world. We are always keen to hear from capable, creative engineers who want to help us accomplish that goal 🚀

Please note: we get lots of successful applications for Backend Engineer, so there could be a delay in scheduling interviews from the initial stage right up until the final interviews. If you’re invited to interview and you have any immediate time pressures, please let us know, as we’ll always do our best to speed things up for you 😊

Our backend engineers have a variety of different backgrounds

We have several non-graduates; only some of us studied Computer Science; one of the team has a degree in Marketing; some of us have worked in huge companies; some have only ever worked in startups; others are former consultants. As long as you enjoy learning new things, we’d love to talk to you.

We encourage an open and transparent working environment

You can get involved in any aspect of the business you are interested in and,following Stripe’s example, all emails in the company are visible in an email archive. We regularly run hackathons in which people build things on our third party API and we contribute to open source software as much as possible. We’ve also made ourproduct roadmap public and give sneak peeks of features in our community forum. Our blog is a good place to learn even more about what we do!

Monzo works in project-based sprints in small, interdisciplinary teams

We have around 150 engineers out of roughly 800 people in total - and we have big ambitions. There are many interesting challenges ahead, and we’re happy for people to move between teams or to specialise, whatever you prefer. As an engineer here you’d be able to work directly with anyone across the company, and we run regular knowledge-sharing sessions so you’ll learn heaps about everything from how banks work to effective communication.

At Monzo you will get to work with a lot of exciting new technology.

We rely heavily on the following tools and technologies:

  • Go to write our application code (there’s an excellent interactive Go tutorial here)

  • Cassandra for most persistent data storage

  • Kafka for our asynchronous message queue

  • Envoy Proxy for RPC

  • Kubernetes and Docker to schedule and run our services (Oliver,our Head of Engineering, gave a great talk at KubeCon on how we use these technologies)

  • AWS for most of our infrastructure

  • React for internal web dashboards

  • We also have two physical datacenter sites with actual cables to connect to various third parties

You should apply if:

  • the work we’re doing sounds exciting!

  • you want to be involved in building a product that you (andeveryone you know) use every day

  • you’re keen to learn more about new technologies and the arcane inner workings of the financial industry

  • you’re comfortable working in a team that deals with ambiguity

  • you’re interested in distributed systems and writing resilient software

  • you have some experience with strongly-typed languages (Go,Java, C, Scala etc.).

At the moment, the following teams are looking for backend engineers:

Product The product backend team work primarily on creating backend services and APIs for our in-app user-facing features. They work closely with our mobile engineers and designers to create a delightful user experience, and to drive growth and retention. Projects that Product backend engineers have worked on recently include Summary (giving people insight into their finances to empower them to spend sensibly) and the Current Account Switch Service (all the hard work to allow users to move to Monzo quickly and easily).

Lending The Lending team works on making borrowing money simple, fair and transparent. They’ve already shipped and scaled overdrafts to hundreds of thousands of Monzo customers and they’ve made it easy to take out a loan without the unfair fees or confusing pricing that you find elsewhere. They work on everything from the way borrowing works in the app, right down to how they move and account for money that our customers borrow. One of the most interesting problems they face is deciding how much to lend and to whom. The team believes that they can make access to credit fairer and more transparent.

Logistics

We can help you relocate to London, we can sponsor visas, and we’re open to remote working (as long as you can spend around 20% of your time in London).

We offer competitive salaries based on skills and experience, which could be anywhere between £40,000 - £100,000 per year.

We care deeply about inclusive working practices and diverse teams. If you’d prefer to work part-time or as a job-share, we’ll facilitate this wherever we can - whether to help you meet other commitments or to help you strike a great work-life balance.

We’re continually hiring for Backend Engineers! Our interview process typically consists of an initial phone screen, a take-home code task, and a half-day on-site interview. We promise not to ask you any brain teasers or trick questions, and we won’t make you code on a whiteboard

London, United Kingdom£40K – £85K
1 year ago

Job Description

Ravelin is looking for a senior backend engineer to lead the development of a high volume fraud technology platform within a small tech team.

A successful candidate will be willing learning new skills (machine learning, neural networks, python, golang, cloud automation etc), turning their hand to necessary tasks and working with complete autonomy.

Whether it’s a smart command line utility or a core internal library, you excel at improving everyone’s lives by removing repetition & common sources of error, and by solving hard problems in accessible ways. You build internal processes that are so reliable they melt into the background but are key to getting work done.

APIs
You’ve been on the receiving end of APIs good and bad, and want to delight our customers with the high quality they expect. You know that whilst everything should be JSON, sometimes you have to get your hands dirty with some SOAP for that critical integration but know how to isolate the contagion.

Requirements

  • Go, Java, Python or C
  • AWS or GCP
  • Docker, Linux
  • NoSQL/Cassandra (not including Mongo & Redis)
  • PostgreSQL

London, United Kingdom£60k - £80k
1 year ago

Job Description

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.

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. 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.
