Software Developer — Backend
Firmware Test Automation (FTA)
Company: Kimbal Location: On-site, Naraina, Delhi Experience: 2-3 years
About the role
FTA is Kimbal’s 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.
What you’ll build
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 (IS 16444 / 13779 / 14697) — we’ll train the right coder.
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.
You’ll do well here if
You like taking a fragile, manual process and making it a clean automated system; you’re comfortable at the seam between web software and physical hardware; and you can pick up meter and protocol domain knowledge on the job.
