Job summary

Quectel is hiring a founding software engineer for our Manaus setup to work on embedded Linux stacks inside cellular IoT modules based on Qualcomm platforms, supporting LTE, 5G and NB-IoT. You will influence tooling, workflows, and customer engagement in LATAM.

The role blends deep kernel and drivers work with customer-facing responsibilities, collaborating with global R&D while building a new operation from day one. Fluency in English and Portuguese is required.

Qualifications

• Bachelor's or Master's in Computer Engineering, Electrical Engineering, Computer Science, or a related field.
• 3–5 years of experience with embedded Linux and cellular modem development.
• Hands-on experience with Qualcomm-based modem SoCs and their firmware.
• Strong C and C++ skills, with understanding of microcontroller/microprocessor architecture.
• Solid knowledge of Linux internals and system programming.
• Comfort with the Linux network stack and packet analysis tools (Wireshark, tcpdump).
• Working knowledge of Linux networking: TCP/IP, sockets, routing.
• Day-to-day experience with Git and Agile workflows.
• Strong problem-solving skills and the ability to work directly with customers.
• Fluent in English and Portuguese; Spanish is a plus.

Responsibilities

• Design, develop, and maintain software modules for Quectel cellular modems (LTE / 5G / LPWA) on Qualcomm SoCs.
• Build and tune Linux-based networking systems for IoT devices and gateways — TCP/IP, sockets, routing, the works.
• Develop device drivers, daemons, and system services on embedded Linux.
• Hunt down issues across the full stack — kernel, Yocto build system, middleware, and applications.
• Use Wireshark, tcpdump, and your debugging instincts to crack tough field and lab problems.
• Support LATAM customers directly: develop new SW features, debug their issues, maintain the SW stack, and improve our demo applications.
• Partner with hardware, integration, and QA teams during board bring-up and validation.
• Contribute to architecture decisions and performance optimization for the next generation of modules.

About Quectel

Quectel is one of the world's leading suppliers of cellular IoT modules, antennas, and connectivity services, with more than 4,000 professionals across 8 R&D centers and 50+ sales offices worldwide. Our technology powers everything from smart meters and connected cars to industrial robots and point-of-sale terminals — quietly enabling billions of devices to talk to the cloud.

The Role

We're hiring one of the founding software engineers for Quectel's brand-new Manaus setup. You'll work on the embedded Linux software stacks running inside Quectel's cellular IoT modules — Qualcomm-based platforms supporting LTE, 5G, and LPWA technologies — and you'll be the go-to software expert for customers across Latin America.

Because the team is being built from scratch, you'll have unusual influence: the tooling, the development workflows, the customer‑engagement model, the way we triage and resolve field issues — these are decisions you'll help make, not inherit. You'll collaborate closely with Quectel's global R&D centers while owning the LATAM software story end to end.

"You get the depth of an embedded Linux job — kernel, drivers, Yocto — and the rare chance to help build a brand-new operation from day one. That combination doesn't come around often."

What You'll Do

• Design, develop, and maintain software modules for Quectel cellular modems (LTE / 5G / LPWA) on Qualcomm SoCs.
• Build and tune Linux-based networking systems for IoT devices and gateways — TCP/IP, sockets, routing, the works.
• Develop device drivers, daemons, and system services on embedded Linux.
• Hunt down issues across the full stack — kernel, Yocto build system, middleware, and applications.
• Use Wireshark, tcpdump, and your debugging instincts to crack tough field and lab problems.
• Support LATAM customers directly: develop new SW features, debug their issues, maintain the SW stack, and improve our demo applications.
• Partner with hardware, integration, and QA teams during board bring‑up and validation.
• Contribute to architecture decisions and performance optimization for the next generation of modules.

What You Bring

• Bachelor's or Master's in Computer Engineering, Electrical Engineering, Computer Science, or a related field.
• 3–5 years of experience with embedded Linux, cellular modem development, or both.
• Hands‑on experience with Qualcomm-based modem SoCs and their firmware.
• Strong C and C++ skills, with a real understanding of microcontroller/microprocessor architecture.
• Solid knowledge of Linux internals and system programming.
• Comfort with the Linux network stack and packet analysis tools (Wireshark, tcpdump).
• Working knowledge of Linux networking: TCP/IP, sockets, routing.
• Day-to-day experience with Git and Agile workflows.
• Strong problem‑solving skills and the communication chops to work directly with customers.
• Fluent in English and Portuguese; Spanish is a plus.

Bonus Points For

• Yocto Project or other embedded Linux build framework experience.
• LPWA experience (NB‑IoT, LTE‑M) and familiarity with cellular certification.
• Prior FAE or customer‑engineering experience in the LATAM region.

The Tech You'll Work With

• Quectel's cellular module portfolio — 5G, LTE‑A, LTE Cat 1/4, NB‑IoT, and LTE‑M, all on Qualcomm SoCs.
• LATAM in production — see the Furukawa Electric LatAm case study for an example of the kind of work you'll support.
• Quectel blog & insights — deep dives on cellular IoT, edge compute, and industry trends.

Why You'll Love Working Here

• Founding-team energy — you're not joining an established office, you're building one. The processes, the culture, the technical playbook — you'll help write it.
• Real impact from day one — your decisions and designs ship inside products used by millions across LATAM.
• Backed by a global leader — startup feel, but with the technology, customers, and resources of a 4,000-person publicly-listed IoT company behind you.
• Direct line to global R&D — work side‑by‑side with our R&D centers in China, Europe, and North America while staying rooted in Manaus's growing tech ecosystem.
• Cutting‑edge technology — 5G, LPWA, AI at the edge, smart camera modules, and the next generation of connected devices.
• Career growth on a fast curve — early team members typically grow into senior technical or leadership roles as the operation scales.
• Customer‑facing exposure — directly shape how leading LATAM brands build their connected products.
• Competitive package — attractive compensation, benefits, and the stability of a global market leader.
• Competitive base salary aligned with LATAM market benchmarks.
• Flexible meal and grocery vouchers (meal allowance / food allowance).
• Health insurance with no co‑pay.
• Life insurance.
• Paid time off.
• International travel opportunities — HQ visits and global trade shows.
