Job summary

Insignis, a fast-growing fintech, is seeking a hands-on engineer to bridge our platform with partner banks and distribution networks. You’ll spend time with problem owners, prototype quickly against partner APIs, and push capabilities into production with proper observability and compliance.

You’ll work across .NET/C#, TypeScript, Vue, and Python to deliver robust, scalable solutions in a hybrid London setting. Strong communication with external partners and internal teams is essential.

Qualifications

• Strong general-purpose engineering in at least one core stack (.NET/C#, TypeScript/Vue), with Python for rapid work.
• Track record of taking something from zero to running in production, ideally in/or near regulated or financial domain.
• Comfort with distributed/event-driven systems, APIs, cloud (Azure ideal; AWS/GCP transferable), containers, and CI/CD.
• Excellent communication; credible and trustworthy in front of partner stakeholders.

Responsibilities

• Embed with partners and internal product teams to understand problems and translate into buildable requirements.
• Rapidly prototype: partner API integrations, white-labelled apps, new deposit-product flows, onboarding tooling; balance speed of learning with design.
• Advance prototypes to early production with robustness, observability, and compliance in collaboration with production engineers.
• Own handoffs: instrument, document, and de-risk; ensure production absorption is feasible.
• Adhere to Insignis regulatory and operational guardrails (Consumer Duty, FCA SYSC, DORA, UK GDPR) and front-load compliance/ISMS.
• Contribute learnings back into the platform to build reusable capabilities and guide next-gen architecture.

Job description

We are a fast-growing, FinTech company looking for a talented and enthusiastic individual to join our team. We are expanding, making this a perfect position if you would like to have a significant impact on our company’s growth and develop your role and career as the business evolves. You will join a team where your ideas will be welcomed and valued.

You'll work at the boundary between the Insignis platform and the wider sector — partner banks, distribution and white-label partners, introducer and agent firms — and alongside our production engineering teams. Your job is to compress the time from "there's a problem or an idea worth pursuing" to "there's a system handling real money or real users," and to do it so that the teams who'll own it long-term can absorb it without inheriting a liability. You'll spend your time roughly equally between building and being in the room with the people who have the problem.

Role responsibilities

• Embed directly with partners and internal product teams to understand the actual problem — often before it's written down as requirements — and translate it into something buildable.
• Rapidly prototype: integrations against partner APIs, white labelled apps, new deposit-product flows, partner-onboarding tooling, internal capability. At this stage you optimise for speed of learning over architectural purity, and you're explicit about that being a deliberate choice.
• Take the prototypes that prove out into early production — enough robustness, observability, and compliance posture to handle live flows — in close partnership with the production engineers who will own them.
• Own the handoff. Instrument it, document it, de-risk it. A prototype that production can't absorb is a failure, not a success.
• Work inside Insignis's regulatory and operational guardrails —Consumer Duty, FCA SYSC, DORA operational resilience, UK GDPR — and know which constraints bind at prototype stage versus hardening. Pull compliance and ISMS early, not as a gate at the end.
• Feed learnings back into the platform: what's repeatedly missing, what should become a reusable capability, where the next-generation architecture should go.

Our stack — Azure-native (AKS), Kafka and event-driven architecture, Kong, .NET/C# on the backend, Vue.js on the front end, Auth0 and Entra ID for identity, Salesforce. We've deployed Claude and Claude Code org-wide and expect Solutions Engineers to be force-multiplied by AI-assisted development, not bystanders to it.

You’ll thrive here if

• You're energised by ambiguity and by sitting alongside the person with the problem rather than waiting for a ticket.
• You can write production-grade .NET/C# or TypeScript, and are equally happy gluing things together fast in Python.
• You have judgment about when "good enough" genuinely is — and when it categorically isn't, because regulated money is involved.
• You can hold an external partner relationship and an internal engineering relationship at once, without drifting into pure account management or lone-wolf building.
• You ship.

Requirements

• Strong general-purpose engineering in at least one core stack (.NET/C#, TypeScript/Vue), with Python for rapid work.
• A track record of taking something from zero to running in production, ideally in or near a regulated or financial domain.
• Comfort with distributed/event-driven systems, APIs, cloud (Azure ideal; AWS/GCP transferable), containers, and CI/CD.
• Excellent communication; credible and trustworthy in front of partner stakeholders.

Nice to have

FCA-regulated fintech, payments, BaaS or open-banking experience; partner-integration or white-label platform work; familiarity with Consumer Duty, or DORA; DDD, Kafka, Kubernetes.

Benefits of the job

• Competitive compensation
• 25 days holiday (exc. Bank holidays)
• Pension contributions
• Private medical insurance
• Employee health and wellness discounts
• Cycle to Work Scheme
• Monthly team lunches

Working pattern

• Hybrid working pattern in London office, 3 days in the office (Tuesday to Thursday), 2 days remote.
