What You'll Do

At Frekuent, we’re not just building payment solutions — we’re creating seamless experiences that move businesses and customers forward. 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.

What you’ll be doing

• 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
• Analyze device and application logs to diagnose field issues, and escalating clearly to firmware/APK engineers when deeper investigation is needed
• 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

Who We’re Looking For

• 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
• Methodical and detail-oriented: analyzing and reproducing bugs, and documenting findings clearly
• 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
• 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:

• 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.
• Flexible schedule – because we trust you to own your time and your outcomes.
• 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.
• A dynamic, fast-growing environment – where each day is unique and every idea counts.
• A collaborative mindset – surrounded by people who genuinely enjoy building together.
• Regular afterwork & teambuilding events – activities to relax, connect, and strengthen team bonds.

Why you'll love it here

At Frekuent, we believe our success is built on our people. 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.

If you're ready to jump into an exciting environment and make a real difference, this is the place for you.
