WiFi Systems Architect (CPE / STB)

The opportunity

A major Polish telecommunications operator is looking for a WiFi Systems Architect to join the team responsible for home devices and Wi-Fi/TV service quality. The company recently migrated to its own network infrastructure and is investing heavily in improving the performance and reliability of customer-premises equipment - routers (CPE) and TV set-top boxes (STB).

This is a hands-on expert role, not a classic network engineer or QA position. The closest description: a device-level WiFi and Android debugging specialist who can go deep into logs, understand what's happening under the hood, and solve problems that have no obvious cause.

The role

You'll be the go-to person for WiFi topics within the team - mentoring colleagues, architecting next-generation STB devices, and evaluating components and vendors. Day-to-day, expect a lot of analysis, debugging, and design work - less clicking through test suites.

Three pillars of the role:

• Mentoring - become the team's internal expert and first point of contact for all WiFi-related topics

• Device architecture - technical architecture for next-generation set-top boxes

• Component and vendor evaluation - assessing chipsets, technologies, and suppliers

What you'll do

• Organise and develop the WiFi lab (STB), oversee tests, and draw actionable conclusions

• Analyse user-reported issues and identify their root causes - including hard-to-reproduce quality defects

• Debug Wi-Fi communication issues in Android TV-based devices

• Build test environments and scenarios to detect problems before deployment

• Create technical requirements and documentation for devices and WiFi

• Collaborate with device manufacturers and influence how WiFi behaves in their solutions

• Build and develop tools for WiFi quality testing and monitoring

• Participate in new device development projects (~8 months) - technical specification, technology evaluation, and go-to-market support

What you bring

Must-have:

• 5+ years of hands-on WiFi experience - practical device-level work, not just standards knowledge

• Experience with CPE / STB or similar home devices

• Log analysis and network traffic analysis (Wireshark, ADB, console, Linux)

• WiFi testing experience and familiarity with test tools (Candela, Spirent)

• Deep understanding of device internals - chipsets, drivers, dependencies

• Experience creating technical requirements and documentation

• Experience working with vendors in an international environment

• Polish at B2/C1 level - all client systems are in Polish (required without exception)

• English at C1/C2 level - for technical discussions and project management

Nice to have:

• TR-398 / TR-069 or similar standards

• Test automation / scripting (any technology)

• Experience at vendors, integrators, or in telecom QA

Team and working model

You'll join an existing team of WiFi/home device/TV engineers. There's already an STB expert on the team you'll work closely with, as well as a broader CPE team (currently 4 people, growing to 5). The team reports to a manager responsible for home devices and services.

• Warsaw (lab and main office) - Warsaw, Katowice, and Wrocław offices available

• UoP: 3 days/week in office

• B2B: location is more flexible, but periodic visits to the Warsaw lab are required
