Junior Support Engineer – Devices
Barcelona | Type: Full-time
We're hiring—and we're doing it the Frekuent way. In a world where technology moves fast, we move with purpose. Being part of our dream team isn't just about a job, it's about enjoying the frekuency. Frekuent is a fast-growing company redefining the payment experience, helping businesses turn one-time buyers into lifetime clients through unique loyalty boosters. We believe that the secret to more sales is giving customers less: cashless, contactless and effortless payment solutions that transform the way businesses operate. You'll join our Devices team, working closely with our QA and support teams as we scale.
This role sits right at the intersection of quality and support: you'll strengthen how we validate firmware and APK releases before they ship, and you'll be a key technical point of contact between support and engineering — helping resolve incidents faster and building the tooling that makes support more self-sufficient over time.
It's a hands-on role spanning firmware, Android APK, apps, and the OS layer — you'll be working with real devices, logs, and field installations, not just a single layer of the stack.
Manually validate firmware and APK releases before they ship, defining and running test cases against device functionality, connectivity, and edge cases
Support test automation initiatives as they're introduced, helping identify what to automate first and validating results
Act as the first technical point of contact for support escalations: ensure tickets are well-documented and reproducible, and resolve straightforward issues directly




Build and improve internal tooling that helps the support team diagnose and resolve issues faster on their own
Support advanced installations, pilots, and new client integrations, providing hands-on technical presence for hardware and connectivity questions
Maintain clear documentation of known issues, workarounds, and troubleshooting guides for support and QA
Degree in Electronics/Electrical Engineering, Telecommunications, or a related hardware-adjacent field is preferred — but equivalent hands-on experience is also welcome
Comfortable with hardware fundamentals (cabling, peripherals, basic debugging via serial/UART, multimeter, etc.) as well as reading logs and navigating an Android/embedded OS
Basic scripting ability (Python, bash, or similar) to build small tools and automate repetitive checks — this is not a software engineering role, but some comfort with code is expected
Genuine interest across the full stack of a connected device — hardware, firmware, Android, and the apps running on top — not just one layer
Strong communication skills — you'll be a bridge between support, QA, and engineering
Fluent in English and Spanish
Naturally proactive, always looking for ways to move projects forward.
While it’s not required, it’s an added plus if you also have:




Prior experience in a QA role, or exposure to test automation practices
Exposure to embedded/Android devices, connectivity (cellular/WiFi/BLE), or POS/unattended retail hardware and software
Experience supporting a technical support/helpdesk team, or working with ticketing systems
What’s In It For You
~ A hybrid model that works – Enjoy the energy of our office 3 days a week and the flexibility of working remotely the other 2.
~ Meal vouchers – Enjoy a monthly support of meal vouchers to make your workdays tastier.
~ Health & wellness – private health insurance and discounted gym memberships to keep both body and mind in top shape.
~ Learning & development – English classes and role-specific training, because your growth is part of our journey.
~23 days of paid time off – plus local holidays, because great ideas need space to rest.
~ Why you'll love it here
We’re a team of non-conformists, committed and solution‑driven individuals, who know that infinity is the limit when it comes to innovation. With plenty of room for personal and professional development, we value creativity, ownership, and collaboration — all driven by a strong culture that fuels our growth.
Be authentic isn’t just a value, it’s our belief that embracing who we are and appreciating diverse backgrounds, experiences and opinions is what truly enriches us.
