Software Engineer

Hi, we’re Griffin! We’re the bank for companies who want to build and launch financial products. We’re a technology platform and a bank: fully regulated, API-first, developer-centric, and purpose-built to serve innovative fintechs and brands who want to build and embed financial products.

We’re moving toward a future where most people access financial services through technology companies rather than high street banks. Companies now embed financial products into their apps so customers can make payments, manage expenses, take out loans, save, invest, and more. Legacy banking infrastructure remains a barrier, so Griffin aims to change that.

Our culture: We safeguard our values by hiring the right people. We operate with high trust and high autonomy, are transparent by default, and support remote-first, asynchronous work so you can work when you do your best.

The Craft Function: We have seven Engineering teams within Craft: Banking, Infrastructure, Onboarding and Financial Crime, Payments, Platform, Cards and Tooling. Each team is cross-functional with Product, Design and Engineering to discover, shape, architect, build, test and run end-to-end features. We aim to move thoughtfully and minimize mistakes, working in an output-driven environment with autonomy; people keep their own hours and there is no micromanagement. Our backend stack includes Clojure, FoundationDB, Bazel, Kubernetes and AWS. Our frontend stack includes CLJS, Reframe, Reagent, React, Stitches, Storybook and Playroom.

As a backend engineer, you’ll be responsible for building one of our core product pillars. You’ll work in one of our Craft teams—exact team depends on your background, current team needs and your preference. Day to day, you might work on banking domain features (onboarding, transaction monitoring, ledgers, payment rails) or SaaS features (invoicing, webhooks, roles and permissions).

Griffin supports two tracks—individual contributor and people leadership. This role focuses on individual contribution with strong hands-on skills, with the option to move into people management over time if you’d like to explore it.

The ideal candidate will have most of the following:

• At least two years of professional experience. We hire across multiple levels—from strong mid-level engineers to senior or lead engineers who can help shape our technical direction.
• Some functional programming experience, ideally with Clojure, but we’re open to Scheme, Haskell, Erlang, Elixir or Scala as well.
• Either a very strong distributed systems background or substantial full-stack experience (i.e., integrating front and backends directly).
• Experience collaborating with Product Managers and UX/UI Designers to build products that solve customer needs.

Nice to haves:

• Experience with the other parts of our stack (Bazel, FoundationDB, Kube, AWS).
• Have worked in domains relevant to what we’re building (banking, payments, billing or broader fintech).
• Experience working in small teams, ideally in fast-paced startup environments.

The interview process:

• Get to know you with a member of our Talent team
• Take-home task evaluating writing and coding in Clojure
• Discussion to learn about your software engineering craftsmanship and mindset, and to explore your experience and collaboration with engineering leadership
• Discussion around deep technical topics with peers, system design, and APIs knowledge
• Griffin culture interview with Grifflings outside of the Engineering Guild, plus an opportunity to meet a founder

If there’s a match, apply via the link below and our Talent team will reach out to schedule an initial conversation and explain what happens next.

We’re remote-first. We have a small London office in Moorgate, but we’re comfortable hiring people to work from anywhere in the UK. About a third of the company is based within occasional commuting distance of London; the rest are full-time remote.

Our goal is for Griffin to proportionally represent the diversity of the working population. We’re building a supportive, empowering and inclusive environment for every member of our team—whatever your race, ethnicity, gender, age, sexual orientation, physical ability, nationality, neurodiversity, or religious beliefs. If you’re part of a group under-represented in fintech, we’d love to hear from you.
