Equilibrium Energy is revolutionizing the clean energy transition by developing innovative grid-scale energy storage solutions. Our technology and market platform helps utilities, independent power producers, and commercial customers optimize their renewable energy assets, improve grid reliability, and accelerate decarbonization. As a fast-growing climate tech company, we're building infrastructure that will shape the future of energy markets and enable a sustainable energy economy.
Equilibrium Energy is a well-funded, Series B clean energy startup backed by some of the most prominent institutional investors in climate. New colleagues will share our vision that a next-generation energy company must be built from the ground up on deep industry expertise combined with an unwavering commitment to modern digital approaches. We’re looking for collaborative, talented, passionate and resourceful folks to join our team and help us lay the foundation for our important mission and ambitious plan.
What we are looking for
The power sector is undergoing its biggest transformation in a century, and legacy tools were not made to handle this level of complexity. Equilibrium is building a new kind of power company that can work with an increasingly intricate energy mix, manage large fleets of resources, and integrate algorithmic and human decision-making with sophisticated insights coming from every part of the stack. We are looking for an experienced Frontend or Full-Stack Engineer to shape and scale this vision, creating the intelligent backbone to power a resilient grid.
What you will do
As a Sr. Staff/Principal Engineer at Equilibrium, you will be instrumental in shaping the future of energy software.
You’ll drive critical frontend architecture decisions and strategic initiatives, shaping the experience for both internal customers and large power companies. We are building a deeply interconnected ecosystem of front end applications within a complex domain, creating software that enables both powerful automation and human agency. You’ll need to navigate complex, ambiguous problem spaces and translate intricate domain requirements into elegant, scalable UIs.
You will also play an important role in the mentorship and growth of junior colleagues, acting as a technical leader and mentor within the engineering team, while embodying a collaborative approach by serving as a key voice to drive technical alignment across multiple programs.
In short: there will be many opportunities for your expertise to shine.
The minimum qualifications you'll need
- A commitment to clean energy and combating climate change.
- Proven experience leading frontend/full-stack engineering at scale, including conception, development and ownership of complex, data-intensive UI/UX architectures, large-scale Typescript/React codebases, and performance optimization strategies.
- Collaboration-driven mentality: work closely with product managers, designers, backend engineers, and data scientists across multiple teams to align technical strategy with business goals and deliver cohesive user experiences. The strongest candidates will have experience working across domains, using technical leadership to unlock everyone’s productivity.
- Demonstrable experience designing and implementing frontend strategies for effectively consuming, visualizing, and interacting with large, complex datasets, including understanding the underlying data models and APIs.
- Proficient in AI-augmented software development (e.g. Gen AI and LLMs, agentic tools, Cursor, Windsurf, etc.)
- Good understanding of security best practices, bonus points if it’s in an enterprise environment.
- Deep expertise with modern testing strategies for frontend applications, including unit, functional, and end-to-end testing frameworks (e.g. Testing Library, Cypress, and Playwright).
- A track record of elevating team performance, mentoring engineers, and establishing best practices that improve engineering quality and productivity.
- Strong communication skills for collaborating within a remote-first company that spans all time zones across EU and the Americas.
Nice to have additional skills
- Background in the energy and power systems sector.
- Proficiency in Python, with FastAPI and common visualization frameworks (e.g. Plotly) being an additional plus.
- Experience with Auth0 to drive user authentication and authorization.
- Experience with observability and error-tracking tooling like Sentry, Grafana, Honeycomb, and Prometheus.
- Experience building on AWS.
- Familiarity with automated build, deployment, and orchestration tools such as CI/CD, Pants, Docker, and Kubernetes.
- An advanced degree in computer science.
