On our roadmap currently is: building out our self-hosted infrastructure to support a hybrid-cloud setup and remove single-vendor reliance, improving how Kubernetes scales, improving the build farm, and building out our PKI infrastructure. We also have plans for a global HTTP routing layer to allow seamless failover between sites.

Our infrastructure as code is written in TypeScript. Where it makes sense, tooling gets written in Clojure. There's some Rust too.

What success looks like:

Infrastructure problems become production problems fast. Success here means thinking ahead - identifying issues with scale, security, or compliance before they affect services.

• You've eliminated an entire class of incidents by fixing the underlying architectural issue.
• You've proven the database and compute platform can handle 10x current traffic volumes by working with backend teams to stress-test it.
• You've cut deploy times in half by rethinking how the pipeline works.
• You've tested multi-region failover under realistic failure scenarios and it worked.
• You've redesigned service discovery to remove networking issues that used to cause weekly firefights.
• When new FCA requirements dropped, you were already compliant because you'd built the infrastructure to handle it months earlier.

To do this, you'll own:

• Infrastructure architecture decisions - how we structure our systems, what approaches we take, what tools we build
• Production reliability - keeping the database, compute, build farm, and deployment pipelines running and improving them
• What other teams depend on to ship - CI/CD, security access, monitoring integration, and the infrastructure that lets engineers deploy safely
• Infrastructure cost and efficiency - managing spend and resource usage across AWS and DataDog

Stack:

FoundationDB, Kubernetes, Bazel, Pulumi, CDK, CircleCI, DataDog, Clojure, TypeScript

Your background:

You'll fit in well here if you have:

• Solid systems experience - you've run container orchestration in production, written infrastructure as code, and understand IP networking well enough to debug it when things go wrong
• Cloud infrastructure experience - you've built and managed production environments, worked with networking, identity management, and compute at scale
• Programming fundamentals - you write code to solve problems. TypeScript, Python, Go, or functional languages are all fine. If your experience only extends to Bash scripting and YAML, we probably aren't a good fit for you.
• Comfort with startup environments - small teams, shifting priorities, high autonomy

We write a lot of our tooling in Clojure - our database control plane, operational scripts, and automation. You don't need Clojure experience coming in, but you'll need to learn it once you're here. If you've worked with functional languages before, that helps.

Regardless, you should be comfortable picking up new languages and approaches as we do find ourselves reading through the codebases of open-source systems and tools we use to understand their behaviour, and they are written in a diverse range of languages we don't use ourselves.

What can we offer you?

We are an early stage startup and we're working hard to expand our benefits package. We're planning to add to this list in the future.

• Remote-first flexibility: Work from anywhere in the UK
• Work from abroad: Up to 20 days a year
• Time off: 25 days’ holiday, bank holidays and a winter break (we shut down between Christmas and New Year)
• Share options: Own a part of what we’re building together
• Pension: Auto-enrolment into our Penfold scheme
• Insurance: Private medical with Bupa (including family cover) and life insurance with AIG
• Wellbeing: 1:1 coaching and therapy session available through Oliva
• Family leave: Enhanced parental leave with up to 6 months on full pay after two years’ service
• AI tools: Everyone has a Claude subscription on us and access to other premium tools
• Your setup: We’ll support you in creating a comfortable and effective WFH environment.

As a bank, we’re committed to maintaining the highest standards of security. This means that the successful candidate will need to complete background screening, and our offer will be conditional upon satisfactory review of these checks. This would include verification of right to work, criminal record, credit history, social media and professional reference checks.

How do I apply?

Are we your next move? Apply via the link below, if there's a match our Talent team will reach out to schedule an initial conversation and talk you through what happens next.

We’re remote-first

We trust people to do great work wherever they are. We hire across the UK and most of our team works remotely full-time. We have a small London office in Moorgate for those who want it, and about a third of the company is close enough to use it occasionally, but there's no expectation to be there. What matters is the work, not where you do it.

Under representation

At Griffin, we’re looking for people who instinctively vibe with our values, behaviours and mission. You’re encouraged to apply, even if your experience doesn’t tick every box. Careers, like life, can take many twists and turns. Your technical expertise and path to where you are today will stand out. We're committed to creating a place where everyone belongs and we welcome diverse perspectives, backgrounds and people who are ready to build a global platform for programmable finance.

Griffin Bank Ltd request that recruitment agencies do not speculatively submit CVs to any employee or associate of our company unless explicitly asked to do so by a member of our Talent team.

Any CVs sent to any member of our team on a speculative basis will not be recognised and we will not accept liability for any fee or commission should we subsequently employ a candidate who applied to us directly or was introduced by an instructed agency that may also have been submitted speculatively by an uninstructed agency.
