Senior Backend Engineer (NestJS / Node.js) — Hybrid in Berlin

Join to apply for the Senior Backend Engineer (NestJS / Node.js) — Hybrid in Berlin role at Unique

Defining how AI and finance work together — securely, intelligently, and at scale. At Unique , we’re building agentic AI infrastructure that financial institutions can trust. Our systems combine deep technical engineering with enterprise-grade reliability — bringing automation, insight, and adaptability to some of the most demanding environments in global finance.

We’ve recently raised our Series A and are scaling fast. Few teams are tackling the complexity of making AI truly enterprise-ready for finance — we’re one of them, and we’re growing quickly.

We’re looking for a Senior Backend Engineer who thrives on deep technical challenges, ownership, and collaboration. If you know how to write heavy processing Node.js code without blocking the event loop, or reason about and extend systems you don’t fully control, this is the environment where you’ll thrive.

Job Requirements

• 5+ years of backend experience with Node.js / NestJS in production.
• Deep understanding of JavaScript/TypeScript internals, async programming, and event-driven design.
• Skilled in PostgreSQL, Prisma, and modern CI/CD (GitHub Actions, Docker, Kubernetes).
• Experience building secure, distributed systems and integrating with complex external environments.
• Strong communicator and collaborator with an ownership mindset.

Job Responsibilities

• Design, build, and scale backend services in NestJS / TypeScript that power AI-driven financial platforms.
• Design and deliver secure, production-ready integrations that make enterprise data usable for AI.
• Work closely with customers and internal teams to deliver scalable, production-ready solutions.
• Own the full lifecycle — architecture, implementation, deployment, and observability.
• Champion best practices in security, reliability, and performance.
• Help shape how our systems evolve as we scale and build new financial use cases.

Job Benefits

• Momentum: Backed by a successful Series A, scaling fast in a market ready for transformation.
• Impact: Build the backend foundation enabling financial institutions to operationalize AI.
• Autonomy: You’ll make architectural decisions and own them end-to-end.
• Hybrid setup: Based in Berlin with flexibility for remote days.
• Security-first culture: Develop systems trusted by leading financial institutions.
• Modern stack: NestJS, TypeScript, Prisma, Postgres, Kubernetes, Azure.

Compensation & Benefits

• Competitive salary + equity options.
• Annual budget for learning, tools, and conferences.
• Inclusive, neurodiverse-friendly culture with flat hierarchies and high trust.
