Join to apply for the Software Engineer role at Griffin

Overview

Griffin is 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 are a remote-first, asynchronous, and flexible team building a modern BaaS platform to help brands embed financial products into their apps and user journeys. Our backend stack includes Clojure, FoundationDB, Bazel, Kubernetes, and AWS; our frontend stack includes CLJS, Reframe, Reagent, React, Stitches, Storybook, and Playroom.

What you will be doing

As a backend engineer you will be responsible for building core product pillars that handle banking, compliance, accounts, and transactions. You will contribute to a scale-ready infrastructure with tens of thousands of requests per second and integrate with multiple payment rails (e.g., Faster Payments, Direct Debit, CHAPS, and various card networks).

Who you are

• Ideally at least 2 years of professional experience
• Some professional functional programming experience
• Either a strong distributed systems background or substantial full-stack exposure (experience integrating front and backends directly)
• Experience collaborating with Product Managers and UX/UI Designers to build products that solve customer needs

Nice to have

• Experience with other parts of our stack (Bazel, FoundationDB)
• Relevant domain experience in payments or core banking systems
• Experience working with small teams in fast-paced startup environments

What can we offer you

• 25 days off a year + winter break and bank holidays
• Remote-first flexibility — work from anywhere in the UK
• Home office setup support
• Share options to own a piece of what we’re building
• 1:1 coaching and therapy through Oliva
• Auto-enrolment into company pension scheme with Penfold
• Enhanced parental leave with up to 6 months at full pay
• Private medical insurance and life insurance (Vitality and AIG)

Security and background checks

As a bank, we require background screening. Our offer is conditional on satisfactory completion of checks including verification of right to work, criminal record, credit history, and professional references.

Process timeline

We aim to move quickly; typical timelines are 2–3 weeks. Steps include:

• Initial phone call with our Talent Team
• Technical and collaboration interview with engineering leadership
• Take-home task in Clojure
• Discussion on technical topics and API knowledge
• Griffin culture interview with team members and founders
