Job Description
Lead C# / .NET Engineer – Tech Lead, Backend
Intetics
• Own backend technical leadership: architecture, code quality, delivery plan, and hands-on implementation for the SAR area-based modules. • Design and implement REST APIs and service-oriented backend components. • Ensure robust observability: • Log key operations, including geospatial calculations and user actions. • Build production-grade metrics (Prometheus/Grafana or equivalent). • Drive performance and reliability engineering, including preparation and execution of load/stress testing up to 3,000 simultaneous connections. • Align the backend with security/traceability needs (auditability, immutable action history, etc.) and support integrations that rely on GOV.ID / QES / BankID (working with stakeholders that provide tokens/certificates). • Coordinate technical work with the project working group, and contribute to inception-stage outputs (detailed business processes + technical design) before implementation. • Contribute to delivery and handover: deployment support, documentation, and warranty period collaboration through rollout support.
Job Requirements
- Strong hands-on expertise in C# and .NET (target: .NET 8+) and designing scalable web backends.
- Proven experience building API-first systems (REST), with strong data modeling and transaction integrity practices.
- Solid experience with relational databases and complex queries; ability to work effectively with PostgreSQL (nice to have PostGIS) teams and data models (you won’t be the DBA, but you must be fluent in how geospatial data is stored/queried).
- Nice to have - practical understanding of GIS-related backend needs (geospatial operations, topology constraints, format exports), and familiarity with libraries like NetTopologySuite / GDAL.
- Experience implementing logging/metrics and building observable systems (e.g., Seq, Prometheus, Grafana or equivalents).
- Experience planning and executing performance testing; ability to define a validated load scenario (vendor responsibility) and run stress tests.
- Ability to lead engineers: code reviews, engineering standards, mentoring, estimation, risk management, and delivery ownership.
- Comfort working in a government/regulatory context where traceability, controlled changes, and formal acceptance processes matter.
- Ability to work with Ukrainian-language UI/UX and documentation constraints (you don’t have to write perfect Ukrainian yourself, but you must plan for it and review content with the team).
- Nice to have:
- Experience with geospatial calculations and data integrity (intersection logic, validations, duplicate checks, etc.), collaboration with GIS engineers; leverage geospatial libraries where relevant (e.g., NetTopologySuite, GDAL).
