Software Engineer, Developer Infrastructure

We’d love to speak with you if:

You have 4–7 years of software engineering experience, with significant time spent on test infrastructure, developer tooling, CI/CD systems, or platform/infrastructure engineering

You're a strong Python developer (pytest preferred) and comfortable reading/modifying C++ test code (gtest)

You've owned CI/CD pipelines end to end; not just maintained them, but designed them to be fast, reliable, and trusted

You think about testability as an architecture problem, not just a coverage metric. You've influenced engineers to refactor code so it can be tested

You're comfortable in Linux/Unix environments and can debug complex issues across hardware and software boundaries

This is a high-leverage infrastructure role. You'll be the engineer who makes every other engineer on the team more productive. You'll build the systems that close the feedback loop between code generation and code verification, so that an engineer (or an agent) can write a change, get an automated signal on whether it works, and iterate without waiting on manual testing.

We already have hardware-in-the-loop test rigs and some device simulators in place. Your job is to expand them, make them robust, and build the scaffolding that lets the whole team write and run tests with minimal friction.

Build the Verification Machine (50%)

You'll own the infrastructure that gives our team fast, reliable signals on whether their code works.

Design and extend device simulators and mocks that reduce our dependency on physical hardware for testing

Our mission is to move humanity off of fossil fuel heating. 20% of US global warming emissions come from homes (that's more than cars!). The largest driver of home emissions is burning fossil fuels for heat. To stop climate change, over 80M US homes need to transition from combustion to efficient, electric heat pumps over the coming decades.

We believe for this to happen the world needs fantastic products that are easy to purchase. Today's heat pumps lack great design, make limited use of software, and are difficult and stressful to adopt. We are building a next generation, beautifully designed, AI optimized home heating and cooling system that is 10x better than what is on the market today.

We are a growing team of ambitious people who truly care about the impact of their work. We are on a mission to accelerate a species-level human transition. For over a million years, we've been burning things to stay warm. It's time to move to a better way of living.

At Quilt, we're on a mission to make clean, efficient heating and cooling accessible to everyone — and we know that heat pumps can play a big role in creating healthier, more climate-resilient homes. But the reality is, climate change and outdated energy systems don't impact everyone equally. That's why we're building a diverse, inclusive team — because we believe the best solutions come from people with different lived experiences and perspectives. We welcome teammates of all races, ethnicities, genders, identities, abilities, and backgrounds, and we're committed to creating a workplace where everyone feels empowered to shape the future of climate tech.

Need accommodations during the hiring process? No problem — just let us know. We're here to support you. (accessibility@quilt.com)
