Backend/Infrastructure Engineer – Founding Team Hire

About the Job

We’re looking for a Backend/Infrastructure Engineer to join as a founding-level hire and help build the core infrastructure powering next-generation AI training environments.

This is a full-time, in-person role in Union Square, NYC (with relocation and visa sponsorship available).

This role is not just about coding—you’ll be shaping the culture, technical direction, and long-term success of the company.

The trajectory here is clear: today you join as an engineer, tomorrow you could be a VP-level leader or even a founder-track builder.

If you’re hungry for ownership, value equity over short-term comp, and want your work to directly impact the future of AI, this is the place to do it.

What’s in it for you?

• $175,000 – $300,000 base salary (flexible for the right candidate)

• 0.6% – 0.8% equity (founding-level ownership with leadership path)

• 100% employer-paid medical & dental coverage

• Unlimited PTO

• Daily team lunches

• Commuter benefits

• Professional development budget

• Relocation + visa sponsorship available

Why this role matters:

• The company already has 7-figure ARR and strong product-market fit.

• You’ll join before the upcoming Series A, meaning your equity is at its most impactful.

• Every hire now helps define the DNA of the engineering team and future leaders.

• This is a chance to build AI infrastructure at scale, not as a cog in a big machine, but as a founder-level engineer.

What you’ll be doing:

• Architect and scale backend systems that power AI training simulations.

• Build across Python, Go, and TypeScript, with full ownership over projects.

• Partner with researchers, customers, and leadership to ship meaningful features.

• Establish engineering best practices for a growing global team.

• Contribute to a hungry, winning-oriented culture where craftsmanship and ownership come first.

What you’ll need:

• 3–6 years of backend/infra engineering experience (flexible for top candidates).

• Strong background in Python, Go, or TypeScript.

• Evidence of impactful early-stage contributions or side projects/GitHub work.

• A track record of growth—someone ready to evolve into a technical leader.

• Comfort with customer-facing collaboration and startup pace.

• A long-term, equity-first mindset with ambition to lead.

Who will thrive here:

• Engineers with a founder mentality, who treat their work like a craft.

• Builders who want to go from engineer → future VP/founder-track leader.

• Team-first contributors who value ownership over ego.

• People energized by fast-paced, high-intensity environments.
