The platform delivers: End-to-end carbon intelligence across Scope 1, 2, and 3 emissions; A scalable, actionable pathway for decarbonization in complex industrial environments; Near real-time insights that enable faster, smarter operational and strategic decisions.

Core Responsibilities:

• Lead the design, architecture, and implementation of scalable APIs, services, and accessibility-first user interfaces.
• Drive the modernization of legacy systems into modular, event-driven, API-first components.
• Deliver AI-native features and improvements across both front-end and back-end, using multiple programming languages where required.
• Provide technical direction and make sound engineering trade-offs around scalability, maintainability, performance, and product impact.
• Own reliability and operational excellence, including telemetry, SLOs, error budgets, on-call rotations, incident response, and continuous service improvement.
• Champion DevOps practices, including CI/CD, deployment automation, monitoring, and application-level operations.
• Collaborate with Platform Engineers as part of a lean DevOps shared service model, while taking responsibility for application-level DevOps within the team.
• Mentor engineers, promote engineering best practices, and help raise the technical bar across the team.
• Champion code quality, documentation, automated testing, performance, security, and maintainability.
• Take full ownership of the quality of deliverables, including test automation, continuous improvement, and production readiness.
• Partner closely with Product Management, Design, AI, Platform Engineering, and other engineering teams on product discovery, technical trade-offs, and delivery.
• Bring a product- and customer-led mindset to solving customer pain points with elegant, scalable engineering solutions.
• Identify technical risks, performance bottlenecks, and opportunities to improve the platform architecture and engineering ways of working.

Qualifications Essential:

• Strong experience in full stack software engineering, with proven capability across both front-end and back-end development.
• Solid experience with modern front-end technologies, particularly React or similar frameworks.
• Strong back-end engineering experience, ideally including GoLang or comparable general-purpose programming languages.
• Experience designing and building scalable APIs, services, and cloud-native applications.
• Strong understanding of DevOps practices, including CI/CD, deployment, monitoring, automation, and incident response.
• Experience delivering secure, observable, high-quality production software.
• Strong focus on code quality, automated testing, documentation, performance, and maintainability.
• Ability to lead technical design discussions and influence architectural decisions.
• Effective collaboration and communication skills, with the ability to work across Product, Design, Platform, and Engineering teams.
• Ownership mindset, with the ability to take accountability for outcomes from design through to production.

Desirable:
