Looking for a strong Mid/Senior Level Go - FinTech- London

:beaver: Hiring London based Go Engineers (Mid-Senior) – Building Real Payment Infrastructure

If you care about:

  • Writing clean, idiomatic Go

  • Designing systems that don’t fall over at scale

  • Concurrency done properly (not just goroutines everywhere)

  • Low latency, high-throughput APIs

  • Production-grade distributed systems

…this might be worth a look.


The Context

We’re building core payment infrastructure at a scaling FinTech.

Not dashboards.
Not internal CRUD tools.
Actual transaction-processing systems moving real money.

Think:

  • Idempotent payment flows

  • Exactly-once / at-least-once tradeoffs

  • Event-driven architecture

  • Failure handling & graceful degradation

  • Observability that actually matters


The Stack

  • Go (primary language)

  • gRPC / REST

  • Kafka (event-driven architecture)

  • PostgreSQL

  • Kubernetes

  • AWS

We care about:

  • Clear interfaces

  • Proper error handling

  • Testing (unit + integration)

  • Performance profiling

  • Simplicity over cleverness


You’ll Probably Enjoy This If

  • You’ve built backend systems in Go in production

  • You understand context propagation & cancellation

  • You think about race conditions before they happen

  • You’ve debugged something painful in prod and lived to tell the story

  • You prefer shipping well-designed systems over over-engineering

Payments experience is a bonus. Strong engineering fundamentals matter more.


Level

Mid-level or Senior
(If you can own services end-to-end, we want to talk.)


If you’re interested, open to a conversation, or just curious about the architecture - DM me or drop a comment.

Happy to share more technical detail.

Hi,

this sounds really interesting.

I’m a Go backend engineer with experience building distributed systems and event-driven architectures (Kafka, microservices, etc.).

I’d love to learn more about the architecture and the role if you’re open to a conversation.

Hi Marco, absolutely! Please give me a call on 0207 600 7888 or send me your CV on amandine.conjat@rothsteins.co.uk and I’ll give you a call back.

Hello,

I am interested, DM shared.

Thanks
Seth
