Why we need you 🚀

We’re growing fast and working on ambitious new hardware projects — and we need an experienced, passionate Senior Mechanical Engineer to help us bring them to life.

You’ll take full ownership of the mechanical design across our current and future products. From early concepts to mass production, your work will shape devices that improve the health and lives of women around the world.

This is a key role on our R&D team, with strong collaboration across product, industrialization, and quality teams — and for the right person, a path toward broader responsibilities in hardware project leadership.

What You Will Be Doing

• Take ownership of mechanical design across current and future products — from concept to production.

• Lead the mechanical development of the next iteration of our wearable breast pump, focusing on comfort, robustness, and high-performance integration of fluid and air systems.

• Optimize and improve existing product designs to increase performance, reliability, and manufacturability.

• Design and prototype mechanical systems that integrate seamlessly with electronics, sensors, and soft materials.

• Create 3D models, technical drawings, and documentation for manufacturing partners.

• Lead design validation through prototyping, testing, simulation, and iteration (3D printing, silicone molding, FEA, etc).

• Support industrialization by working closely with our CM and suppliers — including regular travel to China for supplier visits and production ramp-up.

• Collaborate with product, electronics, and firmware teams to deliver smart, elegant, and reliable solutions.

• Stay ahead of trends in materials, manufacturing processes, and product design.

What Hard Skills We Need to See 🛠️

• Mechanical Design Expertise: Advanced skills in CAD (Onshape, SolidWorks, or similar), with hands-on experience creating elegant, production-ready parts.

• Manufacturing Fluency: Strong knowledge of injection molding, overmolding, silicone and plastic materials, DFM/DFA principles, and tolerance stack-ups.

• Sealing & Integration: Proven experience designing airtight and watertight enclosures, integrating seals, gaskets, ultrasonic welding, and leak-resistant assemblies.

• Actuation Systems: Familiarity with small DC motors, air valves, and precision movement or pumping systems in compact, wearable devices.

• Real-World Product Development: You’ve already brought at least one complex physical product into mass production.

• Analytical Approach: You enjoy solving tricky mechanical problems and iterating based on data and test results.

• Communication: Fluent in English, with the ability to clearly document your work and collaborate with international teams and suppliers.

What Kind of Person We Are Looking For 👤

• Maker Mindset: You’re hands-on, love building prototypes, and never hesitate to get your hands dirty.

• Cross-functional Collaborator: You’re at ease working across mechanical, electronics, industrialization, and product teams.

• Customer-Oriented: You care about making high-quality, delightful products that really help people.

• You are a feminist: You believe every woman deserves access to innovative health solutions. You’re comfortable working on intimate health topics and excited to contribute to positive change.

You Will Shine If ✨

• You’ve worked in a startup or fast-paced hardware development environment and enjoy taking ownership.

• You have hands-on experience with prototyping techniques, soft materials, or sensor integration.

• You enjoy the challenge of building reliable products under tight constraints of cost, size, and scale.

• You’ve shown strong project ownership or played a leadership role in cross-functional product development.
