As a Principal Full Stack Engineer, you’ll lead a team to build-out Phia’s core product and platform from the ground up. You’ll own engineering execution across frontend, backend, and infrastructure, setting the technical direction while scaling teams that move fast and ship reliably. This is a hands-on leadership role for someone who thrives in ambiguity, partners tightly with Product and Design, and knows how to balance speed, quality, and long-term architecture. You’ll define how engineering works at Phia as we grow from zero to one and beyond.
Job Responsibility:
Own engineering execution end to end across frontend, backend, and infrastructure
Define technical direction and architecture while moving fast in a zero-to-one environment
Build, lead, and scale high-performing full-stack engineering teams
Partner closely with Product and Design to turn ideas into shipped, high-quality product
Drive engineering decisions in ambiguous problem spaces and unblock teams to maintain velocity
Establish engineering standards, processes, and tooling that support rapid iteration and reliability
Balance short-term speed with long-term scalability, security, and maintainability
Stay close to the work — reviewing designs, guiding technical decisions, and mentoring leaders
Own production health, performance, and operational excellence as the product scales
Requirements:
5+ years of engineering experience, including senior leadership roles building and scaling product teams
Strong full-stack background with hands-on experience across frontend, backend, and modern infrastructure
Proven track record leading engineering in fast-growth, zero-to-one or early-scale environments
Deep understanding of system design, distributed systems, and scalable architectures
Experience partnering closely with Product and Design leaders to drive product execution
Ability to operate at speed in highly ambiguous environments
Clear, direct communicator with strong technical judgment and influence across functions
