• Architect Embedded Agent Cycles: Transition Mainspring from "AI-assisted" tasks to a model where autonomous and semi-autonomous AI agents are natively integrated into the engineering lifecycle—from code generation and hardware simulation to automated testing and documentation • Workflow Optimization: Identify and re-engineer high-impact engineering bottlenecks, deploying AI agents that act as functional members of the development team • ROI & Performance Measurement: Establish a data-driven framework to measure the impact of AI on engineering velocity, error reduction, and resource optimization. You will be responsible for defining and reporting on clear ROI metrics for all AI initiatives • Standardized Guardrails: Design and implement automated guardrails within the CI/CD pipeline to ensure AI-generated output meets Mainspring’s rigorous safety, security, and quality standards • Responsible Agent Execution: Establish governance frameworks for agentic behavior, including "human-in-the-loop" checkpoints, audit logs, and access controls to prevent drift or unauthorized actions in production environments • Model Evaluation: Build rigorous benchmarking systems to evaluate model reliability and cost-effectiveness, ensuring a lean and high-performing AI stack • Agentic Infrastructure: Design the end-to-end infrastructure required to support multi-agent systems, including orchestration layers, long-term memory (Vector DBs), and tool-use capabilities (RAG) • Build vs. Buy Strategy: Act as the technical authority on whether to leverage third-party AI platforms or develop proprietary agentic tools tailored to our specific hardware-software engineering needs

• Own and drive complex product development programs: Lead a portfolio of programs ranging from focused tactical initiatives to multi-year, company-wide efforts, ensuring delivery against technical, schedule, and business objectives • Program-level decision ownership: Frame tradeoffs, resolve cross-functional conflicts, and drive alignment when priorities compete • Executive and stakeholder communication: Communicate clearly and effectively with senior leadership and external partners to drive decisions, provide program visibility, and escalate risks proactively • Cross-functional leadership: Partner closely with engineering, reliability, test, operations, supply chain, and manufacturing teams to align priorities and streamline execution • Manufacturing readiness and scale: Drive programs through NPI, manufacturing handoff, and production ramp, ensuring design, supply chain, and operational readiness • Tools, process, and systems optimization: Leverage tools such as Jira and enterprise data systems to improve program transparency, execution discipline, and cross-team collaboration • Risk management: Identify technical, operational, and schedule risks early; lead mitigation planning and execution across teams

• Develop system architecture, preliminary designs, and cost estimates from concept through execution handoff • Articulate and support sound technical approaches, ensuring appropriate design integration and tradeoff evaluation • Produce complete, accurate, and timely proposal packages across multiple concurrent projects • Build well-supported cost estimates, proactively communicate risks, and incorporate market inputs into pricing assumptions • Support customer meetings, site walks, and solution presentations as the technical subject matter expert • Communicate technical concepts in clear, structured, and solution-oriented formats across customer and internal stakeholders • Collaborate with Engineering, Product, Controls, Commissioning, and Project Management to support technical feasibility and execution alignment • Contribute to peer design reviews to share technical perspective and strengthen overall solution quality

• Serve as the primary advocate for project success and Mainspring Energy’s lead field representative, coordinating cross-functionally with engineering, logistics, manufacturing, commissioning, and customer stakeholders to ensure successful delivery throughout the full project lifecycle • Lead concurrent turnkey power generation projects, as well as oversee multiple third party developed equipment sale projects, from development through commissioning and closeout • Manage permitting and utility interconnection processes across multiple municipalities and Authorities Having Jurisdiction (AHJs) • Coordinate cross-functional teams (engineering, procurement, construction, QA/QC, commissioning) and external partners to execute safely, eliminate scope gaps, on schedule, and within budget • Own critical path schedule management, proactively mitigating technical, procurement, and construction risks • Oversee contract administration, bid packaging, subcontractor management, and change order negotiation • Drive cost control initiatives to meet and improve project margin targets • Ensure compliance with safety, quality, environmental impacts and risk mitigations, and regulatory standards • Maintain accurate reporting, documentation, turnover packages, and warranty administration • Conduct site visits and job walks, with up to 15% travel required

• Lead the architectural design of site-level control systems, ensuring high-speed, reliable coordination between multiple LGens and balance-of-plant equipment • Design and implement robust communication interfaces using OPC-UA, Modbus, and other industrial protocols to ensure interoperability • Own the vision for our SCADA systems and HMI design, focusing on intuitive operator interfaces and deep diagnostic visibility • Develop strategies for integrating Mainspring technology into Distributed Energy Resource Management Systems (DERMS) and complex microgrid environments • Act as the subject matter expert for the engineering team on commercial power standards, site safety logic, and grid compliance • Work closely with Product and Hardware teams to translate utility requirements and interconnection standards into software specifications
