Client Success Manager | HVAC / Engineering Exp

About Rebar

Rebar is building the next-generation operating system for commercial HVAC, electrical, and plumbing suppliers and subcontractors. Over the past year, our V1 quoting product has scaled to thousands of quotes completed weekly, doubled revenue six weeks into 2026, and gained adoption across many of the top suppliers in North America. Fresh off a $14M Series A backed by leading construction tech investors, we're entering our next phase of growth, and we are looking for a Client Success Manager to support our Success motion.

You’ll work directly with the Client Success (CS), Product, and Sales teams to support clients and build the systems that will define Rebar’s client experience. We’re transforming the $250B HVAC industry with AI-native software—an industry still largely untouched by modern tools. This is your chance to get in early.

The Role: Client Success Manager (Post-Implementation & Growth)

This is not a traditional “CSM” role.

Our Implementation team owns onboarding. We’re looking for someone with industry experience to take full ownership of the client relationship post–handoff—driving adoption, solving day-to-day problems, and ensuring clients get real value from Rebar in their workflows.

You’ll be part operator, part problem-solver, part product feedback loop. You’ll work directly with clients, the CS team, Sales, Product, and Engineering to make sure our software works in the real world, and improves continuously.

This role is high intensity, high ownership, and high upside. If you’re looking for a highly structured, low-pressure CS role, this is not it.

What You’ll Do

• Own the client relationship after implementation—from initial handoff through long-term success

• Act as the primary point of contact for clients managing a book of business

• Drive product adoption and ensure clients are fully leveraging Rebar in their workflows

• Troubleshoot issues in real time and keep clients unblocked

• Build strong relationships with stakeholders across client organizations (from operators to leadership)

• Identify opportunities for account growth, usage expansion, and renewals

• Manage and mitigate risks through proactive outreach and effective escalation management

• Partner closely with Product and Engineering to surface feedback and improve the platform

• Maintain CRM, client messaging, and ticketing systems with high attention to detail

• Build and refine the playbooks that will scale our Client Success function

A typical day might look like:

• Reviewing account health and usage data to identify risks and growth opportunities across your book of business

• 3+ live video calls with clients (mix of QBRs, adoption strategy, stakeholder alignment, and issue resolution)

• Proactively reaching out to key accounts to drive deeper adoption across teams, branches, or workflows

• Partnering with Product and Engineering to escalate trends, advocate for client needs, and close the loop on open issues

• Collaborating with Sales and Implementation on expansions, renewals, and account strategy

• Prioritizing and managing client communication—balancing reactive needs with proactive, high-impact work

What Success Looks Like

• 2 Weeks: You understand the product, key client workflows, and what success looks like for different customer types post-implementation

• 30 Days: You’re managing a book of business, building relationships with key stakeholders, and identifying early signals around adoption, risk, and expansion

• 60 Days: You own client outcomes—driving adoption, leading strategic conversations, and proactively executing on growth and retention opportunities

• 90 Days: You’re a trusted advisor to your clients, influencing how they use Rebar within their business and consistently identifying ways to deepen value and expand usage

Who You Are

• 2+ years in a technical or operational role within the Commercial HVAC/Mechanical industry (e.g., Estimating, Project Management, or MEP Design)

• HVAC industry familiarity (required), you know the ins and outs of the takeoff process

• You take pride in solving real problems for real people

• Your passionate about Client Relationships and driving value

• You move fast and follow through

• You’re comfortable with ambiguity and figuring things out on the fly

• You communicate clearly and confidently with clients at all levels

• You’re energized by being close to the action—not sitting behind dashboards

Nice to Have

• Experience in client success, account management, or sales

• Startup experience in a high-growth, high-pressure environment

• Experience managing ongoing client relationships (post-implementation)

• Familiarity with CRM or ticketing systems

Compensation & Benefits

• Salary: Competitive

• Equity: Meaningful grant, commensurate with experience

• Benefits: Medical, dental, and vision coverage

• Perks: Free lunches and dinners

This is a full-time, onsite role based in NYC’s Flatiron District, steps from Madison Square Park and Union Square. You’ll work side-by-side with a high-performing team, solving real problems in real time, and shaping the future of an industry untouched by AI.
