Trellis is rewriting the insurance experience from the inside out. We’re the tech company behind Savvy, our licensed insurance agency, and we’re bringing clarity and ease to a space known for… the opposite.

We’re a profitable, fast-growing Series A startup backed by General Catalyst, QED, NYCA, and Amex Ventures. As a remote-first team, we move quickly, experiment boldly, and build with intention.

You’ll architect and build intelligent systems that power natural, engaging conversations between users and our platform. Working closely with cross-functional partners, you’ll transform high-level product initiatives into scalable, well-tested technical solutions.

You’ll lead the way on complex projects by defining scope, setting technical direction, and mentoring teammates along the way. You’ll guide the team through tough challenges, offer thoughtful code reviews, and contribute to a culture of continuous learning and collaboration. Whether you’re onboarding new teammates or refining our LLM-driven infrastructure, you’ll be a key force behind our AI innovation.

You will report directly into John Hartley, Head of Conversational AI.

What You’ll Need

While you don’t need all of these to be successful in this role, we think you’ll be more successful the more you have.

• 7+ years’ experience developing software in a production environment

Who You Are

• Meticulous: You pay attention to detail and take pride in what you deliver

• Articulate: You succinctly and effectively communicate verbal and written technical and non-technical ideas and topics

• Opinionated: You bring strong opinions to discussions but are willing to change your mind when presented with new or better information

• Product-minded: You focus on the “why” just as much as the “what” or “how”

• Collaborative : You work within your team and cross-functionally to build consensus and achieve results

• Autonomous : You are self-motivated, able to hold yourself accountable, and can generate high-value work with little direct supervision
