Senior Solutions Engineer

Solutions Engineer | FCA-regulated Fintech | London, Hybrid (3 days in office)

An FCA-regulated fintech in London is hiring a Solutions Engineer. The role covers the platform's integrations with partner banks, white-label and distribution partners, and introducer firms.

About half the job is building: prototyping integrations and new product flows, then taking the ones that work into early production. The other half is working directly with partners and internal teams to define what needs building. Once something is live, you hand it over to the production engineering teams who will own it long-term.

Stack: Azure (AKS), Kafka, .NET/C#, Vue.js, Python.

What you'll actually do -

• Work directly with partners and product teams to find the real problem, often before anyone has written requirements
• Prototype quickly: partner API integrations, white-label apps, new deposit-product flows, onboarding tooling
• Get the prototypes that work into early production, with the robustness, observability and compliance posture live flows need
• Own the handoff. A prototype production can't take over counts as a failure
• Work within Consumer Duty, DORA, FCA SYSC and UK GDPR, and know which rules apply at prototype stage and which apply when hardening
• Shape where the platform goes next

You're the person if…

• You write production-grade .NET/C# or TypeScript and can glue things together fast in Python
• You've taken something from zero to live in production, ideally in a regulated or financial setting
• You're comfortable with distributed systems, APIs, cloud (Azure ideal; AWS/GCP fine), containers and CI/CD
• You know when "good enough" is fine, and when it isn't because regulated money is involved
• You can be credible in front of partners without drifting into account management
• You ship

Bonus points: payments, BaaS or open banking, white-label platforms, DDD, Kafka, Kubernetes.

London, hybrid: Tuesday to Thursday in the office, 2 days remote.
