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. Our V1 quoting product has scaled to 500+ quotes per day and we've doubled our annual recurring revenue in the first six weeks of 2026. Fresh off our $14M Series A (funded by the world’s best construction-tech investors), we’re entering our next phase of growth and are building out our Client Success team.

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 CS motion. 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.

Our first product is live and scaling fast. To keep delivering the exceptional support that got us here, we need an Implementation Manager to own Client onboarding, training, and early-stage success. You’ll work to build the playbook that powers Rebar’s customer experience. We’re tackling a $250B industry that’s barely digitized—this is your chance to get in at ground level.

The Role

With our first product in-market and scaling quickly, we’re focused on maintaining the exceptional client support that’s been core to our growth. As we add more clients and onboard thousands of users over the next 1-2 years, we’re hiring a Client Success Manager to help us manage and grow our client relationships at all levels.

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 CS motion. We’re transforming the $250B HVAC industry with AI-native software, an industry still largely untouched by modern tools. You’ll help translate strategy into execution and play a critical role in scaling the Client Success function. This role is for someone who thrives in fast-paced, high-pressure, high-upside environments, is comfortable with ambiguity, and is obsessive about follow-through.

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:

• 20–30 inbound client messages across phone, email, and chat

• 4–6 live calls with clients (adoption, troubleshooting, relationship management)

• Working directly with product/engineering to resolve issues

• Helping a client deepen usage across additional teams or branches

What Success Looks Like

• 2 Weeks: You understand the product, client workflows, and handoff process from Implementation

• 30 Days: You’re independently managing client communication and handling day-to-day issues

• 60 Days: You own client relationships, drive adoption, and proactively identify and execute on growth opportunities

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: $95k-$120k (depending on experience)

• 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.
