Jobs Developers

Petcube is looking for an Embedded Tech Lead to own the technical direction of our hardware and firmware platform across multiple product lines (cameras and GPS trackers). You’ll be the person who makes the key architectural and system-level decisions, ensures production readiness, and builds a sustainable engineering culture within a small, high-impact team. This is a leadership role first — you’ll guide and support engineers rather than write the majority of the code yourself.

What You’ll Do

• Define and evolve the platform architecture across Petcube’s embedded products
• Make key technical decisions around hardware, firmware, and system design
• Own production readiness: guide products from prototype through mass production and ongoing maintenance
• Mentor and support firmware engineers through code reviews, technical discussions, and design feedback
• Communicate technical risks, trade-offs, and timelines clearly to product and management
• Balance short-term delivery pressure with long-term platform quality and technical debt management

• Drive cross-team alignment on technical decisions that affect firmware, hardware, backend, and mobile

   

What We’re Looking For

• 7+ years in embedded engineering with progressive technical leadership
• Experience launching hardware products from prototype to mass production (must-have)
• Experience working across multiple hardware generations
• Strong system-thinking mindset — ability to see how firmware, hardware, cloud, and mobile interact
• Familiarity with both Embedded Linux and MCU/RTOS environments (doesn’t need to be expert in both, but needs to understand both worlds)
• Track record of mentoring engineers and improving team practices
• Startup or early-stage product company experience (strong plus)

• Willingness to roll up sleeves when needed, but primary value is in direction, not daily code output

   

Tech Stack Across the Platform

C/C++, Embedded Linux, Zephyr RTOS / FreeRTOS, BLE (Nordic), GPS, cellular (LTE-M/NB-IoT), Wi-Fi, IMU, Yocto, CMake, low-power design, video streaming and networking.

Location: Remote — EU (Poland, Romania, Czech Republic, Germany, Slovenia, Estonia, Latvia, Greece, Hungary), US, or Canada

Why This Role

You’ll be the technical leader of the entire embedded platform at a company where firmware is the product. No layers of management between you and the decisions that matter. You’ll shape how the next generation of Petcube devices is built, mentor a small team of strong ICs, and have a direct line to the CTO. If you’ve been looking for a role where your technical judgment genuinely drives the product, this is it.

As a Junior Python Developer, you'll join our engineering team to build the backend systems that power our autonomous AI agent platform. You'll work alongside senior engineers and ML teammates to deliver scalable, reliable services that support real-time agent workflows.

Requirements

• 0–2 years of professional Python experience (internships, open source, or strong personal projects count)
• Strong knowledge of algorithms and data structures, with a solid grasp of time and space complexity
• Clean, idiomatic Python and a good sense for choosing the right tool for the job
• Familiarity with version control (Git) and writing testable code
• A genuine curiosity for how things work under the hood

Nice to Haves

• Participation in competitive programming contests
• Olympiad background in informatics or mathematics
• Exposure to backend development, REST APIs, or databases
• Familiarity with Docker or CI/CD workflows
• Open-source contributions

Why You Should Join

• Competitive equity & pay: get in early and own what you build
• Growth opportunities. Learn directly from senior engineers, take on increasing ownership, and grow into a senior role as the company scales
• Work closely with experienced founders with a proven startup track record
• Move fast, ship fast with no corporate bureaucracy
• Shape the AI revolution in healthcare — massive market, untapped potential

Join our expanding team as a Senior Python Engineer! We’re looking for a proactive tech professional who takes ownership, sweats the details, and takes pride in delivering high-quality software.
