This is a unique opportunity to join a company that has already achieved significant traction, tripling their ARR and handling thousands of live calls daily for Fortune 500 banks and insurers.

The role demands a highly experienced engineer with at least 3 years of startup experience, who is ready to take on significant technical and product responsibilities. As a Founding Senior Engineer, you'll be joining a small, high-performing engineering team of 4 full-time engineers, working in an environment that values rapid shipping, technical excellence, and customer focus.

The position offers a competitive compensation package ranging from $80,000 to $100,000, plus significant equity (0.2% – 1%), along with comprehensive relocation support to San Francisco, including visa sponsorship and housing assistance. This is an in-person role based in San Francisco, reflecting the company's commitment to building a strong, collaborative culture.

Key responsibilities include making architectural decisions, owning the entire product development process, engaging directly with customers, and contributing to complex technical areas including telephony systems. You'll be expected to spend over 80% of your time coding while also helping shape the engineering culture and improving developer experience.

The ideal candidate should have experience as an early employee at a startup, be comfortable with full-stack development, and have a strong product mindset. You should be someone who has previously owned significant projects end-to-end and can thrive in an ambitious, fast-paced environment.

Domu offers a unique opportunity to work with enterprise clients, learn about closing enterprise deals from an engineering perspective, and be part of a team that considers itself A-players and continuously strives for improvement. The company maintains a culture of zero bureaucracy and ego, emphasizing full ownership and trust.

This role is perfect for someone looking to accelerate their career trajectory by joining a promising YC-backed company in San Francisco. The position offers not just a job, but a potential career-defining opportunity to be part of building the gold standard in financial-services voice AI.
