Engineering Manager, Product

Cartesia • San Francisco, CA

13d • $250,000 - $375,000 • Onsite

About The Position

We're hiring an Engineering Manager to help build Cartesia's Product Engineering team as a hands-on technical and people leader. You'll work alongside the engineers building the product surfaces around our models — including Voices, Voice Agents, self-serve growth, billing, and shared product infrastructure — while helping the team grow in size, quality, and impact. This is a player-coach role. You'll stay close to the work, contribute directly when it matters, and earn technical credibility with the team, while also hiring, mentoring, and creating the operating rhythm needed to ship exceptional products consistently. You'll initially embed with the Voices squad and help establish clear ownership across product surfaces that span teams.

Requirements

• 6+ years of product engineering experience, including experience leading or managing engineers at a company with a high product bar.
• Strong current technical ability and the credibility to contribute to architecture, design reviews, debugging, and production-quality code.
• Experience building polished, customer-facing product surfaces and the product taste to explain what makes an experience excellent.
• A track record of coaching engineers, giving direct and useful feedback, handling performance issues, and helping people expand their scope.
• Evidence of leading through context, judgment, and contribution — not only through reporting lines or process.
• Strong cross-functional instincts and experience working directly with Product and Design to set direction and make difficult tradeoffs.
• A track record of hiring strong product engineers in a competitive market, including personal sourcing and closing.
• Comfort moving between visible product work and unglamorous foundations such as billing, files, operational ownership, and on-call health.
• The ability to operate with urgency and clarity in a fast-moving environment where the team and roadmap are still taking shape.
• Genuine excitement about voice AI and building the product layer on top of state-of-the-art models.

Nice To Haves

• Experience in developer tools, AI infrastructure, or products built for technical users.
• Experience helping grow a product engineering team from roughly 5 to 15 engineers while remaining hands-on.
• Experience with PLG, self-serve growth, billing, or other end-to-end product surfaces.

Responsibilities

• Build alongside the team and contribute directly to important product and technical work, especially while the team is growing.
• Lead and develop product engineers through coaching, feedback, career development, and a high bar for performance and craft.
• Help grow the Product Engineering team by personally sourcing, interviewing, and closing exceptional engineers.
• Partner closely with Product and Design to shape what we build, make strong product and technical tradeoffs, and turn ambiguous goals into shipped experiences.
• Establish a predictable execution cadence without adding unnecessary process or losing the team's speed.
• Raise the quality bar through hands-on design and code review, strong technical judgment, and clear examples of excellent product engineering.
• Take ownership of neglected or cross-cutting surfaces — including billing, files, and team rotations — and step into the work directly when needed.
• Help define how Product Engineering should evolve as the team grows, while remaining close to customers, the product, and the code.

Benefits

• Competitive base salary alongside attractive equity package.
• Fully covered medical insurance along with dental and vision for you and your family.
• 9 weeks paternity & 12 weeks maternity leave
• 401(k)
• A monthly stipend to help you get to and from the office.
• Flexible PTO Take as much time as you need to recharge your batteries.
• Lunch, dinner and plenty of snacks, provided daily.
