We’re hiring a full-stack software engineer to join our founding team and help us bring Jane’s vision to life. We’re looking for a teammate who’s product- and customer-obsessed, someone who deeply cares about why we’re building as much as what we’re building. You’ll collaborate directly with the founders to understand customer needs, co-create our product roadmap, make key technical decisions, and own features end-to-end, from ideation to deployment. If you’re excited to build from scratch, move fast, learn from users, and iterate toward product-market fit, this is the role for you.

As our founding engineer, you’ll have the opportunity to start with a blank slate to architect and build Jane V1; shape our engineering culture, tools, and best practices; drive the technical roadmap alongside the founding team; and play a key role in defining Jane’s success and long-term vision.

What You’ll Do Work with founders to scope features and align product roadmap with key goals & strategy

Own features end-to-end, writing clean, reliable, flexible code to ship quickly and iterate

Develop user signup flows, enabling profile creation and integration with utility accounts

Build integrations with utilities and/or third-party APIs to access utility account details

Create integrations with energy providers to sync and monitor pricing data

Implement algorithms to optimize robo-advisor and model impact on energy cost and usage

Build intuitive user-facing web apps for customers and energy partners

Help build the tech team as we scale, shape engineering best practices and company culture

Who We’re Looking For 5–7 years of SWE experience, with a strong track record in early-stage, high-growth startups

Currently a full-stack engineer using TypeScript / JavaScript and React

Experience with RESTful APIs and integrating 3rd party tools into web apps

Writes clean, reliable, flexible code, balancing quality with speed to ship quickly and iterate

An ability to turn business and product ideas into engineering solutions

Passionate about impactful tech, especially for driving progress in climate and energy

Ownership mindset: low-ego, optimistic, self-driven, and adaptable to what’s most critical

Excited to build from the ground up as a core member of the founding team

Tech Stack We’ve built so far using no-code, scrappy tools to move quickly. As our founding engineer, you’ll lead decisions about our stack from scratch. Based on our experience, we envision Node/GraphQL/Postgres (backend); AWS/GCP/Docker (infra); React/TypeScript (frontend); and Jest/CircleCI (testing and CI/CD).

Location We’re based in NYC and are excited to co-create our team and company culture together. As part of our early founding team, this position will be in-person at our co-working space in Williamsburg, with flexibility for work-from-home days (e.g., WFH Wednesdays) and remote periods around holidays.

Comp & Growth Opportunities We offer a competitive salary aligned with early-stage NYC-based software engineering roles, plus equity with room to grow. And in terms of growth opportunities, we’re looking for someone who can grow alongside Jane and expand their role and responsibilities over time, ideal for someone who wants to grow in their careers.
