Senior/Staff Infrastructure Engineer

About the Company

This stealth mode startup is the latest AI native venture incubated by one of the most successful VC firms in Silicon Valley. The team is solving a massive whitespace in enterprise productivity by building a system that transforms internal email into a real-time intelligence and collaboration layer for large organizations. Think: turning asynchronous communication into structured, queryable workflows, without asking employees to change behavior.

Backed by one of the top enterprise software VCs and built by a proven founding team with a track record of unicorn outcomes, this company is positioned to be a breakout player in the AI x enterprise SaaS space. The engineering culture is lean, hands on, and driven by deep technical rigor. The product vision is bold: map and optimize organizational decisions at scale through AI.

What You’ll Do

• Architect and implement the backend infrastructure powering a complex AI-driven platform ingesting and analyzing enterprise email data.
• Design distributed systems that scale with millions of messages per day across global orgs.
• Build secure, enterprise grade systems from day one (compliance, encryption, on-prem options, etc.).
• Work alongside some of the sharpest product and technical operators in Silicon Valley.
• Play a founding role in a new company being spun out - this is not just a job, it’s a legacy build.

Who You Are

• 10+ years in software engineering, building infrastructure for enterprise SaaS or B2B platforms.
• Comfortable working as a hands-on IC; you're not a manager who's been away from the code.
• Background includes time at high-caliber companies (think: Databricks, Scale AI, Stripe, Palantir, or top trading firms).
• You’ve built systems that run in secure, high-availability environments - and you understand the bar for selling to Fortune 500 customers.
• Deep fundamentals in backend engineering and distributed systems. Bonus for Python or TypeScript experience.
• A strong CS degree from a top university or equivalent real-world experience - bootcamp-only candidates won’t be a fit here.

What You’ll Get

• Massive technical ownership on a zero-to-one product build with direct access to visionary product leaders.
• High-impact equity with a real path to co-founder-level upside.
• A front-row seat to what could be the next foundational AI company in the enterprise space.
• True startup energy - fast pace, tight team, big ambition.

Not a Fit If You...

• Haven’t shipped real infrastructure in the last year.
• Have hopped around without building anything meaningful (short stints, no progression).
• Only worked on consumer tools or simple CRUD apps.
• Need remote work - this is an in person role only.
