Equilibriumenergy - Front-End Engineer (Senior/ Staff)
Requirements
• 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. • A commitment to clean energy and combating climate change. • Experience with frontend/full-stack engineering, ideally at scale, including development and ownership of complex, data-intensive applications, and large-scale Typescript/React codebases. • Collaboration-driven mentality: work closely with product managers, designers, backend engineers, and data scientists to deliver cohesive user experiences. The strongest candidates will have experience working across domains and contributing to technical discussions beyond their focus area. • 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 engineering (e.g. Gen AI and LLMs, agentic tools, Cursor, Claude Code, 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). • Strong communication skills for collaborating within a remote-first company that spans all time zones across EU and the Americas. • Background in the energy and power systems sector. • Proficiency in Python, with FastAPI being an additional plus. • Experience with React Context and Zustand • Experience with Tanstack Table and Query • Experience with Recharts, D3, or Plotly.js • Experience with Auth0 to drive user authentication and authorization. • Experience with observability and error-tracking tooling like Sentry, Grafana, Honeycomb, and Prometheus. • Familiarity with automated build, deployment, and orchestration tools such as CI/CD, Pants, Docker, Buildkite and Kubernetes. • An advanced degree in computer science.
Responsibilities
• As a Senior/Staff Engineer at Equilibrium, you will be instrumental in shaping the future of energy software. • You’ll participate in 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. • In short: there will be many opportunities for your expertise to shine.
Benefits
• Equilibrium is composed of deeply knowledgeable industry experts across all our functions, with decades of experience in energy-specific commercial structuring, power systems engineering, machine learning, computational research, operations research, distributed and compute-intensive infrastructure, and modern software & ML engineering. Our experience in the space means we’ve previously built versions of nearly every technical component of our platform. We are now designing them better, and combining them in a holistic and novel way, to achieve global scale and climate impact. We pride ourselves on our deeply empathetic & collaborative culture, honest and direct but respectful communication, and our balanced, flexible, and remote-first work environment. • Competitive base salary and a comprehensive medical, dental, vision, and 401k package • Opportunity to own a significant piece of the company via a meaningful equity grant • Unlimited vacation and flexible work schedule • Accelerated professional growth and development opportunities through direct collaboration and mentorship from leading industry expert colleagues across energy and tech
