Software Developer -Backend

This project is short duration and for 4 to 6 months max only. Role: In-house web platform for validating smart-meter firmware against a library of test cases. You’ll own the server side of FTA - the APIs, data, job orchestration, and reporting - and the glue that connects the web application to the meter-facing test engine. This is backend work with a foot in test automation: you’ll help turn a partly-manual workflow into UI-driven, automated test runs.

You’ll design and build the backend services that power the platform — APIs, data models, and the

workflows that tie the web application to the automated test-execution engine. Typical work includes:

• REST APIs and database models for the core entities of the platform.

• A job/queue system that turns manual configuration steps into UI-driven, one-click test runs.

• Orchestration of the automated test runner, with live status streamed back to the interface.

• Server-side evaluation logic for test pass/fail rules, and its evolution toward a cleaner, more

maintainable model.

• Report generation that converts raw output into usable, well-structured formats.

• Integration with external systems and APIs.

Required skills

• Strong C# / .NET (or a comparable backend language such as Java or Go, with willingness to work in

.NET), building REST APIs.

• SQL / relational databases — schema design, queries, and migrations.

• Python — to orchestrate and extend automated test suites.

• Job queues / asynchronous execution, webhooks, and CI triggers (Jenkins or similar).

• Git and clean version-control practice.

• Comfort working on Linux.

• Ability to read an existing codebase and design against it — interpreting a small expression language,

introspecting registries or generated code.

Nice to have

• Exposure to DLMS/COSEM (IEC 62056), OBIS codes, or other device/industrial protocols.

• Serial / embedded comms concepts — RS485, optical probes, serial-over-TCP, latency debugging.

• Smart-metering or IS-standard domain knowledge

• Raspberry Pi, secure tunneling (Cloudflare Tunnel / Tailscale), or remote-lab setups.

• Building or migrating a rules / criteria engine (expression parsing, AST).

• React / Angular familiarity — enough to wire up a screen when needed.
