Senior Product Software Engineer (Python)

About Tyba Tyba is a modeling platform for energy companies developing, financing, and operating renewable energy infrastructure. Energy companies rely on technical models daily to make crucial infrastructure decisions. Our mission is to make cutting-edge models accessible to cross-functional teams so that companies can build and operate more renewable energy more profitably. We are backed by leading climate and generalist VCs and work with many of the industry’s most innovative energy companies. The Role We are looking for a Senior Product Software Engineer to join our Engineering team and lead key initiatives that deliver high-value, customer-facing products. You will excel in this role if you thrive in fast-paced environments, have a strong sense of ownership, and are comfortable bringing clarity to ambiguous problems. You will drive major portions of the engineering roadmap—from concept to launch—working closely with product, policy, and commercial stakeholders. This is a full-stack role involving both backend and frontend development, with an emphasis on building scalable systems and delivering high-quality, maintainable code. Our Product Tyba has two main products for customers – Asset Operations and Project Simulation Asset Operations: An Auto-bidding platform, powered by a proprietary neural network, that recommends and executes operating strategies based on industry-leading price forecasts and optimization methodology. Project Simulation: A configurable simulation platform enabling developers to model realistic financial and physical outcomes based on location, market dynamics, and battery specifications. You’ll focus most of your time on Asset Operations while staying connected to Project Simulation. Within Asset Operations, you’ll lead key efforts to support new energy markets and strengthen our product in existing markets. You’ll focus on giving our customers more control over their batteries and articulating through the product why the battery chose to take a particular action. Responsibilities Lead engineering initiatives end-to-end. This includes scoping, development (frontend and backend), testing, releasing, and monitoring. Collaborate cross-functionally with Engineering, Product, Policy, and Marketing teams to ensure alignment and push the product forward. Demonstrate a high bar for code quality. Our customers deserve the best. Exceptional communication, half of Tyba is remote across different U.S. timezones Design, advise, and build the next versions of our GraphQL API Debug and fix production issues + participate in an on-call rotation. Required Skills 5+ years of professional full-stack software engineering experience Strong proficiency in Python Proficiency in React Experience with production GraphQL APIs (we use Strawberry) Motivated to learn ClojureScript quickly (ClojureScript is our frontend language) Ability to work cross-functionally, synthesizing requests from non-technical team members and external parties into well-designed engineering solutions Comfortable working in a fast-paced startup environment with evolving requirements Basic proficiency with agentic coding tools (e.g., Cursor, Copilot, Claude Code, Warp Agent Mode): You should be able to leverage AI-assisted development to accelerate your workflow while maintaining a high bar for code quality. This means having the judgment to review machine-generated code critically, understanding where AI tools excel and where they can go astray, and knowing when to trust automation vs. when to write code yourself. Preferred Skills Experience with Recharts, ECharts, or similar graphing libraries Experience with ClojureScript or other Lisp-family languages Familiarity with data engineering tools (dbt, Snowflake, Redshift) Thought leadership in AI-assisted development : You’ve developed workflows, best practices, or tooling around agentic coding — perhaps contributing to prompt engineering, evaluating new tools, or helping teams adopt AI effectively while avoiding common pitfalls Passion for clean energy and the energy transition Tyba’s Technical Stack Tyba’s Asset Operations stack is developed in Python and runs on AWS. We rely on PyTorch for building our neural network architectures. Our backend services span Python, Clojure, and Kotlin, with a data layer built on PostgreSQL and Redshift. Our frontend is built in ClojureScript. It uses the Fulcro library for managing client-server interactions and Tailwind CSS for styling. The frontend and backend communicate using a GraphQL API built using the Strawberry library. While prior ClojureScript experience is not required, we’re excited to find someone who is genuinely interested in learning ClojureScript and growing into the ecosystem over time. You will have strong support and mentorship from the existing Product Eng team as you ramp up. Compensation and benefits Salary : $160k-$200k Benefits : Parental leave, medical benefits and unlimited PTO Equity Options: Opportunity to own a stake in the company through an employee stock option plan. Flexible Work Environment: Hybrid work model, remote work options, and team offsites.
