Founding Engineer

Founding Engineer @ Atlas AI

Location: San Francisco, CA (In-Person Only)

About the company:

• Everyone’s searched Reddit for health answers their doctor didn’t have. Atlas is building a new platform to help patients with chronic health conditions discover the treatments and protocols that actually work. Millions of patients are left to figure these conditions out on their own. We’re changing that.

TLDR:

• We're looking for our first engineer: a full-stack, AI-native builder who will co-own the technical foundation from day zero, working directly with the founder to ship the product.

Why this is special:

• We're solving one of the biggest problems in human health. Over 100 million Americans live with chronic conditions that have no approved treatments. This is a chance to build something meaningful, not another B2B SaaS company.
• The hard parts are derisked. Well-funded by top Silicon Valley investors. Led by a repeat founder with multiple exits. We move fast because we've done this before.
• You're not joining a team, you're building one. This is a day-zero founding role with massive career upside. The kind of work where you look back in five years and say "I built that”.
• This is a founding role with significant equity and room to grow into a larger leadership position as the company scales.

The right candidate will:

• Co-own the product from day one. You'll be a true thought partner to the founder, deeply debating the problems we're solving, the jobs to be done, and how to build it right. You'll translate vision into technical requirements, push back when something doesn't make sense, and co-define what we're building. This is not a ticket-taking role.
• Architect the technical foundation that the rest of the product gets built on top of. You're laying the groundwork the rest of the engineering team will inherit.
• Build across the full stack: spin up scalable backend systems, stand up the applied AI pipeline, and ship a scrappy consumer-facing web app.
• Have strong product intuition. You know what great looks like, and you have good taste for what consumers want.

Who we're looking for:

• 🧠 As a human, you're...
• 💻 As an engineer, you have...

If you're looking for a Monday-Friday schedule, this isn't the right fit. We're building something that will genuinely change people's lives, and we work like it. That means high ownership, occasional late nights, and yes, some weekends. We're not a 996 company and we don't glorify burnout, but the team generally works at least one weekend day and you should be comfortable responding on Slack or pushing code when something needs attention.

Compensation:

• $180k - $350k base (depending on experience) + generous founding team equity.

Our office is located at 44 Montgomery in the heart of downtown San Francisco, near public transit and many great restaurants. We provide daily team lunches, and top-tier healthcare benefits to keep you healthy.
