Sr Software Engineer

Team: Software Engineering

Location: New York, NY

Commitment: Full-time

Workplace Type: hybrid

Key responsibilities will include:

Front-end development: build web applications with modern, interactive UIs for operators and customers
Architect and maintain high-performance backend services and APIs (FastAPI, PostgreSQL) to support real-time microgrid operations, telemetry data pipelines, and optimization workflows at scale
Develop and enhance financial modeling features, building reliable calculation engines and data integrations that support portfolio-level analysis and investment decision-making
Design and validate mathematical optimization models (MILP/LP) using Pyomo and commercial or open-source solvers (HiGHS, Gurobi) for generator dispatch and fleet-level maintenance scheduling, including heuristic approaches, OPH projection, and constraint-based planning
Build and extend simulation infrastructure (rolling dispatch, Monte Carlo scenario analysis) to validate optimization outputs, refine algorithmic approaches, and auto-tune model parameters against operational requirements
IoT and messaging pipelines: design and maintain scalable data ingestion, transformation, and event-driven pipelines (MQTT, AWS IoT, SQS, Sparkplug B)
System design: collaborate with product management and design to deliver robust software products that excite users and achieve business goals
Reliability & observability: implement logging, monitoring, and alerting for high availability microgrid software deployments
Collaboration: work with stakeholders across engineering, operations, and product to turn workflows into production-ready automation
Continuous improvement: assess and adopt new technologies to enhance performance, scalability, and maintainability
