Senior Software Development Engineer in Test (SDET)
Position Summary
We are seeking a Senior Software Development Engineer in Test (SDET) to design, build, and scale the automated test platform that validates BTC Power’s EV charging systems and related products. This role develops the distributed software, simulation environments, and hardware-in-the-loop (HIL) infrastructure that exercise firmware and embedded Linux software, grows the automated regression coverage that gates every firmware release, and partners with firmware, software, systems, and hardware teams to validate real chargers on the bench and in the lab.
The ideal candidate has a strong software-engineering background in Python, distributed and service-oriented systems, and test automation, plus hands-on experience automating laboratory hardware. They are comfortable owning test infrastructure end to end, contributing to architecture and design discussions, triaging failures across the full stack, and improving engineering quality, release velocity, and certification readiness.
Key Responsibilities
- Design, develop, and maintain the Python test-automation platform that gates every firmware release
- Grow automated regression coverage for EV charging flows and build HIL/SIL simulation
- Build and own CI/CD pipelines that make automated regression a reliable merge and release gate, with reporting and telemetry that surface pass/fail and root cause
- Triage and reproduce failures across the full stack (test framework, adapters, sequencing, and charger firmware) and drive defects to closure
- Partner with firmware and systems engineers to improve testability and support OCPP certification
- Participate in design and code reviews and release-readiness activities, and maintain technical documentation for the platform and interfaces
- Mentor junior engineers and provide technical guidance as needed
Required Qualifications
- Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related field
- 5+ years of experience in software test automation / SDET or software engineering roles
- Strong Python (frameworks, services, async automation)
- Experience building test-automation frameworks and writing maintainable test code
- Solid experience testing REST and WebSocket APIs and asynchronous, service-oriented systems
- Experience with distributed systems, Docker, CI/CD, SQL / relational databases, and Linux
- Strong analytical, debugging, and log-analysis skills across distributed components, with methodical defect isolation
- Effective communication and ability to work across teams
Preferred Qualifications
- Experience with EV charging protocols (OCPP 1.6J / 2.0.1, ISO 15118 / DIN SPEC 70121), smart charging, and security profiles
- Hardware-in-the-loop testing, laboratory instrumentation, and CAN bus
- Embedded C programming exposure
- Experience supporting products through validation, release, and manufacturing
- Experience mentoring junior engineers or leading technical workstreams
Key Skills / Competencies
- Strong technical ownership of test infrastructure
- Structured debugging and root cause analysis across distributed systems
- Cross-functional collaboration
- Attention to quality, reliability, and automation
- Strong written and verbal communication
- Ability to mentor and support other team members
