Staff Backend Engineer

Staff Backend Engineer 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're looking for a software engineer to join our Asset Operations Backend team and help power the clean energy transition. In this role, you'll work at the intersection of data science enablement and robust backend systems—operationalizing cutting-edge optimization and forecasting models while building the scalable infrastructure behind our growing portfolio of battery storage assets. Our auto-bidding platform synthesizes price forecasts and bid optimization algorithms to deliver market-beating returns for our customers. You'll lead key initiatives that ship high-value features, working closely with cross-functional teams and going deep on the intricacies of power markets and their associated systems. This is a high-impact role at a startup where your work directly accelerates the energy transition. You'll split your time between supporting our data science and optimization teams (who work with specialized Python libraries like cvxpy and neuralforecast) and building robust backend services and system architecture. You'll help shape how we evolve from our current architecture toward a more modular microservices approach across Python, Clojure, and Kotlin. Tyba’s Product Tyba has two main products—Operations and Project Simulation: - Operations: Auto-bidding platform, powered by a proprietary neural network, that recommends and executes operating strategies based on industry-leading price forecasts and optimization methodology. Our platform delivers revenue outcomes in the top 5% of ERCOT assets. - Project Simulation: Configurable simulation platform where developers can model realistic financial and physical outcomes based on location, market dynamics, and battery specifications. As a software engineer on the Asset Operations Backend team, you'll primarily work on new features and initiatives for the Operations product backend. There are plenty of opportunities for collaboration on other portions of the product, including optimization and market orchestration. Responsibilities - Lead feature initiatives end-to-end: Scope, develop, test, release, and monitor new features—primarily backend, with collaboration across the frontend team - Partner with data science and optimization teams to operationalize ML models and optimization algorithms into production systems - Design, build, and maintain backend services that power real-time battery dispatch, bidding, and energy market operations - Performance engineering: Identify, profile, and address computational bottlenecks in a live bidding system that must communicate with market systems on strict timelines - Build and improve data pipelines and ETL processes using dbt and Python - Develop integrations with market entities (QSEs in ERCOT, Scheduling Coordinators in CAISO) and site telemetry systems - Contribute to infrastructure-as-code using Terraform/OpenTofu and manage AWS services (EKS, RDS, Redshift, S3, Kinesis) - Evolve our CI/CD practices, building on our existing CircleCI foundation - Enhance and steward system reliability: Conduct system migrations with minimal downtime, debug and fix production issues, and participate in an on-call rotation - Break apart monolithic services into well-designed microservices - Contribute across our polyglot stack (Python, Clojure, Kotlin) Required Skills - 5+ years of professional software engineering experience - Strong proficiency in Python, including experience with data processing librari ...
