Technical Lead (f/x/m)

Tasks

• Own architecture and technical design: decide what to build and how in a regulated environment.
• Design for security and scale: secure-by-design, sound identity and access, and reliable performance under load.
• Set and maintain the technical bar: quality assurance, release and change management, IT security.
• Own verification: the testing strategy and CI gates that prove what ships is correct and on-spec.
• Build practical AI leverage: agentic workflows with the evaluation and guardrail mechanisms that make AI output reliable.
• Be the technical face to customers: engage senior client-side architects in workshops and due diligence.
• Support the growth of the engineers around you through mentoring, code review, and technical guidance.
• Coordinate the team: work allocation, delivery rhythm, and day-to-day execution.

What we build:

(1) a privacy-first data-sharing platform that lets banks share financial-crime intelligence without exposing each other's raw data, built on multi-party-computation technology from our partner Roseman Labs;

(2) an AI-driven fraud-management pipeline using LLMs for analysis, detection-rule discovery, case preparation, and automation.

Requirements

What we’re looking for

We do not expect you to check every box. We are looking for someone with strong engineering judgment, people skills, and the ability to own technical direction from day one.

Required

• 6+ years building production software, with the depth to contribute hands-on and help guide technical decisions.
• Hands-on AI development (a must): coding agents (Claude Code, Codex, Cursor) on real work; builds agentic systems, not just prompts a chatbot.
• Strong distributed-systems and API design skills, with a security-minded approach to OAuth/OIDC and data protection.
• Rigorous about quality: comfortable shaping automated testing strategy and CI discipline, and verifying rather than assuming.
• A systems and critical-thinking mindset: able to reason about risk in both software and the surrounding process or policy.
• Experience in highly regulated, process-driven industries is a strong plus; banking/FinTech is especially relevant. Familiarity with GDPR, BaFin/MaRisk, PSD2, SOC 2, or ISO 27001 is helpful.
• Strong customer-facing communication and the ability to work well with technical and non-technical stakeholders.
• Cloud experience with GCP preferred (or AWS/Azure), plus IaC, containers, and CI/CD.
• Fluent English.

Desirable: German; Python (FastAPI), React/TypeScript, GCP stack; data-intensive pipelines over large transaction datasets; privacy-enhancing tech / MPC; anti-financial-crime domain (AML/KYC/fraud).

Tech stack: Python/FastAPI; React, Vue.js, TypeScript, Vite; Keycloak/JWT; GCP (GKE, Cloud SQL, Cloud Run, GCS, Artifact Registry); Terraform, Docker; GitHub Actions; Ruff, mypy, pytest, ESLint, Vitest; Claude Code and Codex.

Benefits

What makes us different

We offer a genuine career step into management, with room to grow as the company scales. In the technical leadership role, you own the architecture and technical direction, set the standard, and build the hard parts yourself.

We value thoughtful engineering, direct communication, and practical problem-solving. We also use AI tools where they genuinely improve engineering output and are looking for someone who is curious, pragmatic, and open to learning.

• Attractice compensation.
• Flexible hybrid work model (Frankfurt + home office within Germany).
• High ownership and real impact from day one.
• Modern technology stack, including AI and privacy-enhancing technologies.
• Flat structures and fast decision-making.
• Collaborative, international team culture.
• Work on high-impact products that help fight financial crime.
