• 45 million calls handled with a 99.9% uptime

Backed by Accel, Atlantic Labs, and Singular and trusted by over 1,000 customers, our growth leads an industry shift toward sophisticated and accessible conversational AI.

About the Role

We’re looking for a Staff or Lead Frontend Engineer to drive our frontend architecture, lead
technical decision-making, and grow the frontend discipline at Synthflow. You’ll be our
strongest IC (80%) while also leading and mentoring the frontend team (20%). This role is
both technical and strategic—you'll directly influence the frontend product and tech roadmap
and ensure tight alignment between design, product, and backend teams.

What You'll Do

• Lead architecture and development of our frontend platform using React,
  TypeScript, and Tailwind.

• Own and evolve the frontend technical roadmap—performance, scalability, DX, and
  testing.

• Collaborate closely with backend and infra teams to ensure smooth end-to-end
  system design.

• Build polished, performant, and highly interactive features used by thousands of
  businesses.

• Mentor and support other frontend engineers through code reviews, pairing, and
  design sessions.

• Help shape cross-functional planning and the broader product roadmap.

• Maintain high quality and stability through robust testing (Jest, Playwright, etc.).

• Lead with pragmatism—prioritize shipping fast without compromising long-term
  quality

What You Bring

• 6+ years of experience building modern web applications, with deep expertise in
  React + TypeScript.

• Proven track record of leading architecture and driving technical direction.

• Passion for UI/UX detail, performance, and clean code.

• Experience mentoring engineers and fostering a culture of engineering excellence.

• Startup mindset: you move fast, think independently, and own outcomes.

• Experience with cloud platforms (GCP or AWS) and modern CI/CD workflows.

• Excellent communication and cross-functional collaboration skills.

Bonus

• Working knowledge of Python and FastAPI—a big plus for aligning effectively with
  backend teams and bridging full-stack workflows.

What We Offer

• High-impact role: Influence architecture, roadmap, and team direction.

• Remote-first: Flexible work from anywhere.

• Fast-moving environment: Ship quickly, iterate often.

• Cutting-edge stack: Build with the latest tools and libraries.

• Competitive compensation: Strong salary, equity, and benefits.
