Founding Product Manager

Rebar is building the AI operating system for commercial HVAC, Electrical, and Plumbing.

Over the past year our quoting platform has processed tens of thousands of projects across North America and we’ve doubled our revenue in the first 6 weeks of this year. Our customers include many of the top firms in the industry. Some of these companies are running billion dollar construction projects on workflows that still look like it’s 1985.

Construction is 10% of GDP and still massively underserved by software. We are changing that.

We recently raised a $14M Series A from leading construction tech investors and are entering our next phase of growth. We are building a set of AI native products that will define how this industry operates.

We are looking for a Product Manager who wants to build real products, move fast, and take ownership early. You will help define how AI changes one of the largest industries in the world.

This is product hire #1.

You’ll work closely with the founders to help shape Rebar’s product direction—what we build today, next month, and over the long term.

Our customers rely on Rebar throughout their entire workday, and feedback is constant, direct, and grounded in real workflows. You’ll spend time talking with users, understanding how they work, and helping ensure we stay focused on the highest-impact problems.

This is a hands-on, high-ownership role. It’s a great fit for someone who wants to learn quickly, take initiative, and contribute to building something meaningful from the ground up.

You will:

• Partner closely with founders to drive product decisions and execution

• Engage regularly with customers to understand workflows and pain points

• Identify and prioritize high-impact problems to solve

• Improve and expand the core product experience

• Contribute to launching new products and features

• Turn customer feedback into clear, actionable product direction

• Help build and refine how we plan and ship product

• Collaborate with engineering and design to iterate quickly and deliver high-quality work

• Support alignment across customer and internal feedback

This role is for someone who likes talking to users, identifying real problems, and turning them into products.

You’ll thrive here if you:

• Enjoy working in fast-moving environments where priorities evolve

• Are comfortable navigating ambiguity and figuring things out as you go

• Take ownership of your work and follow through on outcomes

• Care about building products that have real-world impact

This role may be especially interesting if you:

• Are curious about starting a company one day

• Want to work closely with founders and experienced builders

• Are looking for early ownership in a growing company

• Are motivated by learning quickly and taking on new challenges

We’re looking for someone with 3+ years of product experience, but we care most about your ability to build, learn, and execute.

We’re excited about candidates from a range of backgrounds, including:

• Software or mechanical engineers who moved into product

• Product managers in vertical SaaS or construction tech

• People who have worked on complex, real-world workflows

You might be a strong fit if you have:

• Experience contributing to shipped products

• Thoughtful product judgment and decision-making skills

• Comfort working through ambiguity and evolving priorities

• Strong organizational and communication skills

• Familiarity with common product and collaboration tools (e.g., Linear, Jira, Figma, Miro, etc.)

Helpful but not required:

• Experience with AI-driven products or workflows

More than any specific background, we value the ability to take a messy problem and turn it into a shipped product that delivers real value.

• Equity: Meaningful equity package

• Medical, dental, and vision coverage

• Free lunches and dinners

This is a full time onsite role in New York City in the Flatiron district.
