ABOUT E2B
E2B is a fast-growing Series A startup with 8-figure revenue. We've raised over $37M since our founding in 2023. Our customers include companies like Microsoft, Perplexity, Hugging Face, Manus, and Groq. We're building the next hyperscaler for AI agents.
ABOUT THE ROLE
This is the first business operations leadership hire at E2B. The company has scaled from $1M to 8-figure ARR in under a year, raised a Series A, and is now preparing for the next stage of growth.
You'll own everything that isn't engineering, GTM, or design. Finance ops until our Head of Finance lands. Legal admin and contracts. People ops and onboarding. Office logistics across San Francisco and Prague. Vendor management. The internal tools that make the company run.
This is a hands-on role for the first 6 to 12 months. You will personally run payroll, negotiate the office lease renewal, and fix the broken Notion. As the company grows, this becomes a COO-track role with a real team underneath you.
You'll partner directly with Vasek (CEO) and Tomas (Head of Engineering).
WHAT YOU'LL DO
- Build the operating cadence. Weekly leadership rituals, monthly board prep, quarterly planning. Today these happen ad-hoc. You make them repeatable.
- Run people ops end-to-end. Offers, onboarding, payroll across US and EU entities, benefits administration, equity grants, performance review process, offboarding. Partner with Talent on recruiting ops where the recruiting machine spills into HR (offers, references, background checks, work authorization).
- Own legal admin. Customer contracts, vendor agreements, NDAs, contractor MSAs for our EU hires. You won't be drafting from scratch, but you'll be the person turning around redlines, managing outside counsel, and keeping the contract tracker honest.
- Run office and team logistics. Two offices, two countries, two payroll regimes, occasional team offsites, equipment provisioning, real estate decisions. The boring infrastructure that lets engineers ship.
- Own vendor and tool sprawl. Every SaaS bill, every renewal, every "do we still use this?" question. Procurement, security review, cost optimization.
- Set up the bench. As scope grows past one person, you'll hire your replacements: an HR/people lead, a finance hire, eventually a head of legal. You'll define those roles and run those searches.
WHAT WE'RE LOOKING FOR
- 6+ years in operations, with at least 2-3 years operating at a Series A or Series B startup that scaled headcount through 30 to 100. You've watched a company double in size and you know what breaks.
- Generalist DNA. You're comfortable owning finance one week, legal the next, and rewriting the offer letter template on a Friday night. You don't need a defined function to be effective.
- Strong with numbers. Comfortable in spreadsheets, can read a P&L, can model headcount and burn. You don't need a CPA, but you should not need to hand the model off to be useful.
- Real ownership track record. You've personally built or rebuilt at least two of: a payroll process, an offers / equity process, a contracts pipeline, a close cycle, a board reporting cadence, a vendor management process. Not "managed a team that did", but actually built.
- Operates at the speed of engineering. We ship fast. Operations needs to keep up.
- Excited to work in person from San Francisco. You'll be sitting next to our CEO and the leadership team.
NICE-TO-HAVE
- Prior chief-of-staff role at a venture-backed B2B startup.
- Experience operating across US and EU entities, including the realities of EU contractor models, GDPR, and entity setup.
- Experience scaling people ops and recruiting ops together. We're hiring fast and the two functions touch constantly.
- Background in B2B SaaS finance, especially with usage-based revenue.
- Ex-consulting (Bain / McKinsey / BCG) is fine if you've spent the years since actually operating, not just running reports.
What it's like to work at E2B
We're a fast-growing startup with in-person (4 days on-site, 1 day WFH) offices in San Francisco and Prague, Czech Republic. We already generate 8-figure revenue and work directly with top-tier AI companies like Manus, Genspark, Lindy, ClickUp, Groq, Artificial Analysis and other exciting teams pushing the frontier of AI.
We offer healthcare, vision, and dental insurance, unlimited PTO, 401k, and a variety of perks for in-office employees.
