Senior Full Stack Engineer

Our client is an AI company building autonomous digital workers that automate specific jobs from start to finish. Instead of selling software, they sell the result of the work itself. Their AI digital workers, like "Alice," an AI Sales Development Rep, have already generated millions in revenue for companies like Brex and Otter AI.

Founded in 2023, the team has grown to 40 "pirates"—ex-founders and founding employees from unicorn startups like Brex, along with entrepreneurial operators from companies like Revolut and Amazon. They're a high-velocity, high-ownership team backed by $75M in funding.

Our client is looking for a Senior Full-Stack Software Engineer to help shape the future of AI and digital workers. This is a chance to own products and problems end-to-end, driven by a core value of velocity. You will have a direct impact on the company's growth, as they aim to hire 5–30 new engineers.

You will be responsible for:

• Architecting and building new workflows within products.
• Bridging communication between applied research, go-to-market, product, and engineering teams.
• Identifying and implementing architectural improvements and scalability solutions.
• Driving technical decisions and best practices across the engineering team.

We are seeking a senior full-stack engineer who thrives in a chaotic, high-velocity environment and has a relentless ownership mindset.

Must-Haves:

• 4+ years of full-stack (frontend and backend) experience.
• Strong background as a technical founder, founding engineer, or engineer at a hyper-growth startup.
• Expertise in TypeScript, with experience in Next.js, Node.js, and React.
• A strong ability to work with speed, compressing multi-week development cycles into days.
• Willingness to work on-site, 5 days a week, in San Francisco.

Bonus Points:

• A stable work history with strong career progression.
• Notable achievements or side projects.
• Experience with Python, Twilio, Vercel, or AWS.

• Salary: $150,000–$200,000 per year
• Equity: Competitive package
• Visa Sponsorship: TN and H1B transfers are available
