Jobbeschreibung

Own outcomes, not just tickets

• Lead a squad of 2–4 engineers (mix of senior / junior) to deliver measurable product impact
• Set clear goals and success metrics (e.g., latency / reliability / adoption), break work into small, reversible slices, and ship on a steady cadence

Design and build production systems

• Architect and implement .NET services / APIs with SQL Server for a multi‑tenant B2B SaaS platform
• Make pragmatic trade‑offs : idempotent writes, rate limiting, caching / ETag, indexing and query shaping, back‑pressure, and failure‑mode handling

Operate what you build

• Instrument services with logs / metrics / traces; hold the line on p95 / p99 performance and availability SLOs
• Run incident reviews that produce systemic fixes and documentation (runbooks, dashboards)

Prioritise for the business

• Partner with PM / Design / Customer teams to translate goals into scope; cut or resequence work when data changes
• Keep stakeholders aligned with concise updates, risks, and owner / dates

Create clarity and accountability

• Set explicit expectations with your reports; give direct feedback; follow through with support and check‑ins
• Use lightweight mechanisms—PR templates, decision records, checklists — to make accountability routine

Grow people and the codebase

• Mentor engineers via pairing, reviews, and 1 : 1s; create growth plans and celebrate momentum.
• Keep standards high : tests where they matter, clear interfaces, and intentional debt management.

Leverage AI effectively

• Use AI assistants to accelerate boilerplate and documentation, and verify outputs with tests and metrics.
• Help the team adopt safe practices (no secrets, anonymised data, prompt discipline, simple evals).

Collaborate across the product suite

• Work with the iOS / Android / Web SDK teams to ensure that backend APIs and contracts are stable, well‑documented, and easy to integrate.
• Support enterprise client integrations (often in sport), balancing reliability with delivery speed.

Hire and onboard

• Contribute to interviews and rubrics; onboard new teammates with clear goals, docs, and a first‑week win.

Must‑haves

• Technical leadership : you’ve led a small team (2–4 engineers) to ship production software, setting direction, unblocking work, and owning outcomes end‑to‑end
• Practical problem solving : you start from constraints and business goals, enumerate options, make trade‑offs explicit, and choose the smallest reversible step that works
• Clear, direct communication : you set crisp expectations with reports, write succinct PRs / decision records, and give kind‑but‑candid feedback that changes behaviour
• Ownership & accountability : you finish hard things, leave systems better than you found them (tests, telemetry, docs), and make accountability routine rather than personal
• Flexibility & product sense : you can cut scope to hit outcomes, re‑prioritise quickly when data changes, and keep stakeholders aligned
• Learning mindset & AI fluency : you adopt new tools fast (including AI assistants) and verify outputs with tests / metrics, respecting privacy and data safety

Nice to have :

• Cloud & infra : Azure (or equivalent), CI / CD, feature flags, safe rollouts / rollbacks
• Experience across media / SaaS, SDKs, or high‑throughput event ingestion
• C# / .NET expertise : strong experience with modern .NET (.NET 8+), building and operating Web APIs; comfortable with Minimal APIs or controllers
• SQL Server depth : confident with schema design, indexing, query shaping, and concurrency (transactions, isolation levels, deadlocks, idempotency)
• Interest in sport and fan engagement (helpful, not required)
