Senior Software Engineer

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. 

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 Python/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. 

• Recognise when a plausible agent-generated solution is architecturally wrong, unsafe, or unnecessarily complex — and review agent-generated work before it merges. You own the outcome. 

Raise the bar 

• Contribute reusable patterns, subagents, and evals to the shared libraries the wider org adopts. 

• Pair with colleagues to lift the team's overall capability — coaching is part of the job.
