• Lead engineering at Mason while continuing to build.
• You'll work directly with our CTO to make architecture decisions, drive delivery, and help engineers do the best work of their careers. Initially, expect roughly 70–80% hands-on engineering and 20–30% leadership. You'll be in the code, reviewing designs, solving difficult problems, and making sure the team follows through.
• We're looking for someone Sai can lean on to run engineering independently while he spends more time with customers and prospects. A strong technical lead, staff engineer, or former founder could be a great fit.
• Mason is accelerating development of the built world with AI. We turn fragmented documents, databases, emails, and operational knowledge into a company brain people and agents can use to automate work and eliminate errors.
• We're growing fast - we have an 8-figure pipeline of projects and are looking for great engineers and builders to join our team.
• Our founding team includes a repeat founder who sold his last company to Coinbase, a former tech lead at Meta Superintelligence who co-created Meta AI, and a development director who built $2B+ of projects.
• Technical direction. Design and build the backend, data, and AI systems behind enterprise deployments. Make clear architecture, vendor, and build-versus-buy decisions.
• Delivery. Turn priorities into plans and ownership. Spot risks early, challenge weak assumptions, and unblock the team.
• Engineering quality. Set practical standards for code, security, testing, observability, and operating what we ship.
• People. Coach engineers, give specific feedback, and handle accountability conversations directly and thoughtfully.
• A stronger foundation. Turn customer-specific work into reusable systems, and help hire and develop the team as we grow.

• 4+ years of engineering experience, with substantial recent ownership of production software.
• Evidence of leading engineers or a substantial project with multiple contributors. Tell us what improved because of your leadership.
• Strong system-design judgment and the ability to get into code, data, and root causes yourself.
• A record of making tradeoffs, setting priorities, and delivering through uncertainty.
• Clear communication with founders, engineers, and customers, including the difficult conversations.
• Your strongest area could be backend systems, data, infrastructure, or applied AI. A previous Head of Engineering title is optional. Current technical depth and a record of making a team more effective matter a lot.

• Help shape engineering while the important decisions are still open. You'll have direct access to the founders, authority over how we build, and responsibility for systems customers depend on.
• As Mason grows, you'll help turn a small team into an excellent engineering organization.
• Python, TypeScript, Node.js, SQL, AWS, enterprise data platforms, AI model APIs and agent SDKs, workflow orchestration, and production infrastructure. Bring depth in relevant systems and the judgment to choose tools well.
• CTO was previously a tech lead at Meta Superintelligence and co-created Meta AI
• Small, intense, low-ego. High ownership, direct feedback, board game nights, and lots of laughs.
• Apply once. Tell us what you've built or led - we'll consider you across relevant openings. Let's talk :)
