At EQ, you’ll join a tight-knit group of brilliant, curious, and adventurous people who bring the same energy to collaboration as they do to innovation. 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 We are looking for Software Engineers to contribute across our end-to-end platform. Our software engineers work across cloud infrastructure and distributed systems, agentic systems, data engineering, ML engineering and MLOps, simulation ecosystems, complex workflow orchestration, microservices mesh, application development and security. Our software engineers supercharge design and delivery of our product development activities while helping to build and lead an engineering capability that is the core of the company’s strategy and identity. If you want to fight climate change and love modern tech stacks, clarity of product vision, and exceptional colleagues, this role is for you! In the near-term, you will work with other software engineers, data engineers, infrastructure engineers, ML engineers, data scientists, researchers and product managers to execute our ML- and AI-infused product development plan en route to growing our company. Have a specific interest in a particular part of our technical stack? No problem...we’re looking for technical leaders across our ecosystem. In the medium-term, you will cultivate our software engineering function by nurturing a culture of experimentation and delivery. You will design, write and optimize software to support our end-to-end product development ambitions, helping to build the core of our competitive differentiation. What you will do Lead the design, development, testing, delivery and support of software systems across our technical stack that drive our end-to-end product development ambitions. Agentic systems - build internal agents to automate and enhance company workflows. Build a stack for agents to enhance customer facing products. Cloud and distributed systems development - contribute to building and maintaining our cloud-native platform and infrastructure; K8s, cluster management, linux containers, etc. Data Platform and Engineering - our use cases are varied and so are our data engineering needs. From stream, batch, pub-sub, queuing, state stores, virtualization, complex data models and closed-loop pipelines, we’ve got a little bit of everything. ML Engineering and MLOps - we aim to infuse EVERY business process with ML and AI, relying on closed-loop decision-making at every valuable juncture. Simulation ecosystem - our ML- and AI-centric workflows need training and testing. Workflow orchestration - we live in the land of complex, autonomous, multi-step sequential workflows operating in a distributed runtime with low latency requirements. Service mesh - we rely heavily on reuse of core microservices to keep application development productivity high, which requires thoughtful service mesh management. Application development - we’ve just started designing and developing across our anchor product suites, each focused on leveraging a common platform and service core. DevSecOps - security is inherently embedded within our development and operations practices, and we leverage bespoke security techniques for some unique exposures. Assist in product development strategy, design, planning and productivity. Contribute your unique technical, user, and market knowledge to product strategy. Contribute to product and architectural design. Contribute to product roadmapping, resource planning and sprint management. Contribute to product development productivity improvements, including best practices, technical documentation, code reviews and automation / utility / abstraction packages. Serve as a member of our technical team across both engineering and research. Collaborate asynchronously with engineers, researchers and product managers across time zones to design, build and ship code. Contribute to technical strategy and planning across the company. Represent Equilibrium in external venues, including presenting work at conferences and contributing to open-source projects.
