Founding Backend/Platform Engineer (Remote) // MobileBoost

We are looking for a motivated Backend/Platform Engineer to join our remote team and help build the foundation of our AI-native QA solution. This is a unique opportunity to join before our Series A and have a major impact on a fast-moving product and team backed by Y Combinator (S21).

About Us:

We’re a Seed Stage startup founded by veterans of the consumer and mobile app space, with 15+ years of experience. Our product GPT Driver is an AI-native solution for testing digital products, starting with functional end-to-end automation for mobile apps—a space where existing tools fall short. Our vision is to expand across Web, Desktop, and into non-functional testing like performance and accessibility. We have been first movers in our space (launched early 2023) and are working with world-class mobile teams including Duolingo, Salesforce, and Wealthsimple.

About the Role:

• Own and develop the platform layer of our AI-powered product, including runtimes and supporting backend systems.
• Collaborate closely with a small, skilled team of frontend and fullstack AI engineers to define, implement, and scale our systems.
• As a generalist, you enjoy solving problems across the stack and aren’t afraid to explore new territory.

What We’re Looking For:

• 3+ years of relevant engineering experience, ideally with exposure to fast-paced startup environments.
• Strong experience building and maintaining cloud-based backend systems.
• Experience (or strong interest) in running mobile emulators/simulators and headless browsers in isolated environments.
• Self-motivated and comfortable working in a fully remote setup.
• Excellent communication skills and a collaborative mindset.

What We Offer:

• Competitive compensation: $4,000 - $7,000/month based on experience.
• Remote-first culture with flexible working hours.
• Equity options for long-term ownership and upside.
• A chance to shape the technical foundation of an innovative AI product.
• High ownership and autonomy in decision-making.
