Senior Software Engineer
Senior engineer on TOPdesk's AI-native 'Phoenix' team builds and modernises the Knowledge Base of its service management platform, delivering production work through agentic workflows with Claude Code as the primary collaborator. Spans the legacy Java/MS SQL stack and the modern TypeScript/Vue/Azure/Kubernetes stack.

Skills
Must have
- At least 5 years of experience in Java
- Strong production engineer with current, daily, hands-on agentic delivery practice (Claude Code, Cursor, Aider, or equivalent)
- Experience in at least one of: TypeScript/Vue, Azure-hosted systems
- Deep software-engineering judgement independent of any tool — strong testing instincts, comfort with operational concerns, ability to spot plausible but wrong agent output
- Comfortable in ambiguity and inside legacy codebases; communicates well in writing
Nice to have
- Experience modernising or decomposing a heritage platform in production
- Reusable prompts, subagents, evals, or CLAUDE.md conventions you have built and shared with a team
- Hands-on with MCP tool integrations or building agent workflows beyond a single editor session
- Depth across multiple stacks rather than a single one

About the role
As a Senior Software Engineer, you deliver production work — including legacy modernisation — through agentic workflows, inside the teams setting the operating model for the rest of TOPdesk engineering.
The work is real and customer-facing: you'll build and modernise TOPdesk's Knowledge Base — expanding existing components, shipping new features, and improving the underlying technologies — for a service management platform used by millions of people every day. Some days that's an accessible, polished user interface; other days it's making the backend fast and reliable; often it's both across the stack.
You work with Claude Code as your primary collaborator: framing problems, orchestrating agents to build and modernise real product, and standing behind the verification. Working this way is the heart of the role, not an add-on.
What this is not: A traditional senior engineering role with optional AI tooling bolted on top. Building agentically is how the work gets done here.
The team
You join team Phoenix, one of the first teams adopting our AI-native SDLC, reporting to an Engineering Manager, proving it in production on real customer-facing systems. Phoenix is a cross-functional team spanning back-end, front-end, UX, testing, and product — you deliver alongside a UX designer and a Product Manager, and work with platform teams to get code to production.
- Owns and evolves the Knowledge Base end to end, from UI to backend.
- Ships legacy-modernisation and product work through agentic workflows.
- Builds the shared prompt and agent libraries the wider org adopts.
What you'll do
Build agentically
- Frame and decompose problems, orchestrate agents to implement them, and verify the result.
- Build new agentic product capabilities, and modernise pieces of the legacy Java/MS SQL platform on the modern TS/Vue/Azure stack.
Work with agents, stay accountable
- Write implementation briefs and acceptance criteria before invoking agents.
- Curate context aggressively — the right files, constraints, and invariants; lean on CLAUDE.md conventions, subagents, and MCP tools to scale beyond single-shot prompting.
- Design verification before or alongside implementation: tests, runtime checks, migration validation, observability, and rollback planning — plus the evals that catch regressions automatically.
- Handle agent permissions, context, secrets, and dependency changes with care, and keep agent-generated change sets small, understandable, and maintainable with reviewable evidence behind them.
