• Implement benchmarks: Implement AI benchmarks within our evaluation infrastructure (primarily using the Inspect library) to expand the suite of capabilities we track. Develop our existing suite of benchmarks so we can quickly and painlessly evaluate new model releases. • Develop new benchmarks: Contribute to the development of brand new benchmarks. You will have the opportunity to pitch and prototype your own ideas in addition to helping out with existing projects. • Collaborate: Work closely with researchers, analysts, and other engineers at Epoch AI to ensure evaluation data and outputs are accurate, insightful, and effectively integrated into our research products and publications.

• Own and evolve critical catalog systems, including product onboarding, attribute management, data enrichment, validation workflows, and product readiness tooling. • Design and operate scalable services and data models that ensure product information is accurate, complete, consistent, and available to downstream systems. • Drive discovery with Product, Merchandising, Data Science, and Operations partners to identify high-impact problems, evaluate tradeoffs, and define clear technical roadmaps. • Independently lead initiatives from concept through production rollout, including technical design, implementation, launch, and measurement of outcomes. • Improve catalog data quality by building systems that detect, prevent, and resolve incomplete, inaccurate, or inconsistent product information. • Ensure catalog workflows support efficient merchandising operations and help teams prepare products for sale at scale. • Mentor engineers through code reviews, architecture discussions, technical feedback, and shared ownership of engineering standards. • Instrument, monitor, and tune systems for reliability, performance, scalability, and cost efficiency. • Work collaboratively with cross-functional partners to align technical solutions with business needs and operational workflows.

• Translate complex energy concepts, utility structures, and technical findings into clear, actionable terms for non-technical decision makers across all client and prospect interactions. • Lead client-facing meetings to discuss energy usage, billing mechanics, and delivery cost components, including capacity and transmission charges, power factor, peak demand performance, and demand response programs. • Conduct cost-benefit analyses for energy efficiency upgrades, on-site generation, power storage, and electrification initiatives including compliance pathways such as NYC Local Law 97. • Serve as owner's representative on engagements where 5 is part of the project team, managing vendor and contractor relationships on the client's behalf to protect their interests and keep projects on track. • Monitor and communicate new utility programs, incentives, and regulatory changes that impact energy costs, then work collaboratively with clients to develop strategies that minimize spend and optimize their site's energy consumption. • Host Lunch & Learns and knowledge sessions for client facilities teams covering energy fundamentals, emerging programs, and building best practices. • Join prospect and client meetings alongside 5's advisors to provide technical depth, answer complex questions, and help close opportunities where engineering expertise makes the difference. • Contribute to improving 5's internal data workflows and client deliverables so that complex analysis is consistently presented in formats that are intuitive, visual, and decision-ready.

• Partner with product managers to understand business requirements and implement technical solutions • Collaborate with UX/UI designers to implement intuitive and accessible user interfaces • Develop, test, and maintain efficient, reusable, and reliable code using modern frameworks and languages • Participate in peer code reviews and provide constructive feedback • Optimize system performance, scalability, and reliability for post-deployment • Work with SQL and cloud-based storage solutions (e.g., Azure Blob Storage, Data Lake) • Create and maintain unit tests and integration tests • Troubleshoot and resolve application issues • Identify and address technical debt as part of ongoing development • Contribute to architecture and design decisions under guidance from Principal engineers • Apply best practices for mobile, web, and backend systems • Design and consume RESTful APIs within microservices architecture • Create and maintain clear and accurate technical documentation • Stay informed about emerging technologies and industry best practices • Communicate progress, risks, and blockers to team members and stakeholders • Collaborate effectively with cross-functional teams • Use tools like Azure DevOps, Teams, and Lucid Chart for effective collaboration
