Who we're looking for
We're looking for a hands-on technical leader who loves turning messy, real-world problems into products people rely on, and who builds with AI coding agents as a natural part of how they work. You'll own the communication stack that connects law firms with their clients, starting with voice and extending across fax, email, and SMS. You'll partner closely with engineering leadership and product, guide one or two engineers, and see your work land in front of customers in weeks.
What you'll do
- Own the Voice Stack: Lead the design, build, and operation of Supio's voice capabilities. Take a hard, high-impact problem from idea to reliable production
- Connect Every Channel: Build and improve the pipelines for fax, email, and SMS, including intelligently routing inbound messages to the right case so law firms never miss what matters
- Turn Requirements into Solutions: Translate ambiguous product needs into practical technical designs. Think through how real users will interact with the system and shape what we build
- Lead and Elevate: Guide one or two engineers with clear direction, thoughtful code reviews, and sound engineering practices that fit a fast-moving startup
- Build with AI First: Use AI coding agents and custom tooling to plan, build, review, and ship faster, and help raise the team's AI-native craft
- Run What You Ship: Take ownership of production quality through monitoring, on-call, and continuous improvement of the systems you build
Qualifications
- Experience: 8+ years of software engineering experience, including building and shipping user-facing products in a hands-on capacity
- Education: Bachelor's degree in Computer Science or a related field, or equivalent practical experience
- Technical Skills: Full stack engineering with strong backend depth, and experience building distributed systems that run across multiple servers
- AI Application Experience: Hands-on experience building applications with AI agents or LLMs, from design through production
- AI-Native Engineering: Demonstrated, day-to-day fluency building with AI coding agents, such as planning with agents, reviewing their output, and creating custom skills or tooling
- Engineering Fundamentals: Strong system design, testing, and code review practices, with a practical sense of which engineering principles matter most at a startup's scale
- Product Judgment: Sound instincts for user experience, and the ability to turn half-formed product requirements into well-scoped technical solutions
- Leadership: Experience guiding and mentoring other engineers while remaining a strong individual contributor
- Ownership and Communication: Comfort operating autonomously, communicating clearly with technical and non-technical teammates, and following through on hard problems
Nice-to-haves
- Experience building with voice or telephony
- Experience with messaging pipelines (SMS, email, fax) or message routing and classification
- Startup experience, especially during growth from a small team to a larger one
- Experience owning production systems and on-call for them
