What you'll do
At Frekuent, we’re not just building payment solutions — we’re creating seamless experiences that move businesses and customers forward. As a Senior QA Engineer – Devices, you’ll own and drive the quality of our unattended POS device as a whole: firmware, the Android POS app, and the device releases we ship to the field.
This role is hands-on and high ownership. You’ll define quality strategy, build automation and tooling, improve processes and CI/CD, and help the team ship faster without sacrificing reliability.
What you'll be doing:
- Define and drive the device quality strategy: test approach, coverage goals, release criteria, and clear go/no-go gates
- Build and maintain automated test suites across the device stack (software components, update packages, and critical user flows), with a strong focus on integration and regression
- Improve CI/CD and release tooling: pipelines, test execution/reporting, reproducible releases, and streamlined validation processes
- Partner closely with engineering teams to improve testability, instrumentation, and diagnostics, including evolving test frameworks/SDKs and internal tools
- Define acceptance criteria and validate hardware/OS drops and device readiness across the lifecycle (including EVT/DVT/PVT/MP), ensuring stable behavior before field deployments
- Feed production learnings back into quality: participate in incident/L3 loops, run targeted exploratory/manual validation when needed, and convert recurring checks into automation
Who we’re looking for
- Bachelor’s degree in Computer Science, Telecommunications Engineering, Electrical/Electronics Engineering, or a related field (or equivalent practical experience)
- Proven experience as a Senior QA / Test Engineer in devices, embedded systems, or hardware-adjacent products
- Strong track record building test strategy and automation in fast-moving environments, including improving processes and release discipline
- Comfortable writing code for tests and tooling (e.g., C and/or Python), and collaborating with developers to strengthen test infrastructure, improving what exists and building missing pieces where needed
- Strong debugging mindset: able to isolate failures across firmware/app/device boundaries and communicate clearly what’s broken, why, and what to do next
- Fluent in English and Spanish, with excellent communication and organizational skills.
- Strong execution and problem-solving skills — you’re not afraid to tackle challenges head-on.
- Takes accountability and consistently owns the outcome throughout the process.
- Embraces feedback as an opportunity for growth.
- Naturally proactive, always looking for ways to move projects forward.
- Comfortable speaking up and proposing bold, creative ideas that add value.
While it’s not required, it’s an added plus if you also have:
- Experience testing Android-based devices (AOSP/embedded Linux exposure is a plus) and working with release constraints typical of embedded products
- Familiarity with hardware validation workflows and lab tools (basic instrumentation, fixtures/jigs, EVTs/DVTs/PVTs, acceptance criteria with vendors)
- Experience with CI/CD systems and advanced test setups (hardware-in-the-loop, on-target automation, reliability/soak testing)
