Mechanical Engineering Lead

Becoming a Mechanical Engineering Lead at Sort A Brick is a rare opportunity to lead the mechanical design and development of high-performance, computer vision-integrated, electromechanical systems from the ground up. If you’re excited about robotics, automation, and reimagining how things are built– we’d love to meet you.

The mechanism built from LEGO

Help Us Build the Future of LEGO® Brick Sorting

  • Across homes around the world, countless boxes of mixed LEGO® bricks sit untouched – bricks built to endure, waiting to be transformed into new creations. While these pieces are meant to be reused, most people prefer building sets over sifting through a mess of mismatched parts. That’s where we come in.

  • Sort A Brick is a tech startup with a bold global vision and a deeply meaningful mission: to make the reuse of toy building bricks both affordable and sustainable – for the sake of the next generation.

  • We’re developing an AI-powered, automated sorting line capable of identifying and organizing tens of thousands of unique LEGO® elements with remarkable speed and accuracy. Our goal? To turn chaotic collections into neatly sorted sets, at an industrial scale. We've already built a working fleet of prototype machines – and now, we're searching for a Mechanical Engineering Lead to elevate our hardware to the next level.

Responsibilities

  • Develop long-term plans for company machinery based on the overall business goals.

  • Generate machinery design concepts and detailed manufacturing drawings using CAD software.

  • Organize "quick and dirty" experiments to test potential solutions.

  • Coordinate subcontractors handling machinery manufacturing.

  • Provide support during the installation and commissioning of equipment.

  • Set up the maintenance of the operating machinery.

Must-Have Qualifications

  • Bachelor’s degree in mechanical engineering or a related field.

  • 3–5 years of experience in mechanical design or machinery development, particularly in systems involving conveyors, robotic arms, optical inspection devices, or pick-and-place machines.

  • Proficiency with 3D CAD software for developing machinery designs and manufacturing drawings.

  • Hands-on experience in prototyping and conducting experiments to validate mechanical design solutions.

  • Experience in coordinating manufacturing and R&D subcontractors.

  • Effective communication in English, suitable for technical collaboration and documentation.

Preferred Qualifications (Nice-to-Have)

  • Experience in integrating optical system setups (e.g., cameras, lenses, lighting systems).

  • Experience in integrating computer vision into conveyor-based or similar systems.

  • Experience in translating business objectives into practical mechanical engineering goals.

  • Master’s or PhD degree in mechanical engineering or a related discipline.

  • Familiarity with simulation/analysis tools and principles of Design for Manufacturing/Assembly.

What we offer

  • Competitive Salary: €5,000–€8,000/month (gross), commensurate with your experience and seniority.

  • Significant Stock Options: Turn part of your salary into a stock option to become a co-owner and directly benefit from the success of a fast-growing, high-potential startup.

  • Flexible Working Model: Choose between fully on-site or hybrid arrangements. Partial on-site presence in Lithuania is required, but permanent relocation is not mandatory. Candidates based outside Lithuania will be expected to travel periodically to our Lithuanian facility for essential phases such as system integration, testing, and strategic planning.

  • Dynamic Team Environment: Collaborate with a passionate, experienced, and result-driven team that values innovation and open communication.

  • Career Growth: Gain exposure to cutting-edge technologies and actively contribute to meaningful projects with substantial real-world impact.
