You’ll help turn problems or ideas into live systems handling real money or users, balancing speed of learning with reliability. You’ll thrive if you enjoy ambiguity, can write production‑grade .NET/C# or TypeScript, and can juggle external partner relationships with internal

Qualifications

• Strong general‑purpose engineering in .NET/C#, TypeScript/Vue with Python for rapid work.
• Track record taking something from zero to production, preferably in regulated/financial domain.
• Comfort with distributed/event‑driven systems, APIs, cloud, containers and CI/CD.
• Excellent communication with partner stakeholders.

Responsibilities

• Embed with partners and internal teams to translate problems into buildable solutions.
• Rapid prototype integrations against partner APIs and white‑label apps.
• Move prototypes into early production with robustness, observability, and compliance.
• Own the handoff: document and de‑risk to enable production absorption.
• Work within regulatory guardrails and involve compliance early.
• Feed learnings back into the platform to shape reusable capabilities.

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 worthy of pursuit" 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 in 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/Cambridge} office, 3 days in the office, 2 days remote.
