About Us

nWe are a dynamic team of young engineers, domain experts, and seasoned sales professionals dedicated to providing comprehensive turnkey solutions for complex challenges in Signal Processing. Our expertise spans the cutting-edge technologies in Signal Processing, addressing critical needs in the Defence and Aerospace sectors. Our offerings encompass a wide range of solutions, from tactical radios and radar systems to extensive research and mission-critical applications.

nAbout the role

nWe are hiring a Python Backend Engineer to take ownership of high-throughput backend services. You will work alongside our front-end and C# application teams to build the infrastructure that ingests, processes, and routes real-time data streams across our platforms.

nThis role is for someone who enjoys asynchronous Python, complex data-flow problems, and the discipline of building production systems that need to run reliably under sustained load.

nResponsibilities

n

n
- Data Ingestion & Processing: Design backend services that handle continuous, high-frequency data streams and telemetry from multiple sources, including raw and binary protocols over TCP/UDP.
n
- API & Service Development: Build robust, scalable REST and WebSocket services using FastAPI, with proper schema validation, error handling, and observability built in from the start.
n
- Event-Driven Architecture: Implement and operate pub/sub messaging systems to enable reliable data distribution across microservices.
n
- Database Design & Optimization: Model and query relational and time-series stores efficiently — raw events, derived state,



and aggregated roll-ups — with attention to write throughput and query latency.
n
- System Integration: Collaborate with hardware/embedded, front-end, and C# teams to define clean contracts and ensure reliable data flow across system boundaries.
n
- Engineering Discipline: Write tested, reviewed, and documented code; participate in design discussions; contribute to deployment, monitoring, and operational practices.

nQualifications

n

n
- Experience: 3-4 years of professional backend software engineering experience, primarily in Python.
n
- Asynchronous Python: Strong working knowledge of asyncio and concurrent programming patterns for high-throughput I/O.
n
- API Frameworks: Production experience with FastAPI (or comparable async frameworks such as Starlette, aiohttp, or Sanic) and pydantic-based schema validation.
n
- Message Brokers: Hands-on experience with at least one event streaming or message broker platform — Apache Kafka, RabbitMQ, NATS, or equivalent.
n
- Databases: Proficient with PostgreSQL and capable of writing optimized SQL; comfortable with schema design, indexing, and query profiling.
n
- Time-Series Data: Working familiarity with time-series databases (e.g., TimescaleDB, InfluxDB, QuestDB)



and the trade-offs of heavy-write workloads.
n
- Networking: Solid grasp of TCP/UDP, WebSockets, and HTTP/REST; able to debug at the protocol level when needed.
n
- Platform & Tooling: Comfortable on Linux, Git-based workflows.
n
- Testing & Quality: Demonstrated practice with pytest, unit and integration testing, and CI pipelines.
n

nGood to have

n

n
- Binary Protocols & Telemetry: Experience parsing custom binary frames, working with raw telemetry, or interfacing with hardware or IoT data sources.
n
- Geospatial Data: Familiarity with PostGIS, GeoJSON/KML, or coordinate-system handling.
n
- Systems Interoperability: Experience interfacing Python with C/C++ libraries via ctypes, cffi, pybind11, or shared library bindings.
n
- On-Premises Deployment: Comfortable building and operating systems in air-gapped or LAN-only environments, not exclusively cloud-managed.
n
- Education: B.E./B.Tech in Computer Science, IT, ECE, or a related discipline.
