Senior Backend Engineer

📋 Description

• Take total technical ownership of key platform components, shaping direction and bringing clarity to ambiguous problems while ensuring solutions are well-designed, scalable, and maintainable.
• Consistently write production-ready, self-documenting code that requires minimal revision, and actively improve testing strategies, non-functional requirements (performance, security, scale), and test infrastructure.
• Tackle systemic bottlenecks and architectural risks across multi-service configurations before they hit production, utilising highly systematic debugging approaches.
• Mentor other engineers, lead technical discussions, and perform rigorous code reviews to leave our systems, practices, and people stronger than you found them. Your influence will go far beyond your own delivery to help make Octopus an incredible place to be an engineer.

🎯 Requirements

• 5+ years experience of robust backend development with deep expertise in systems design, database optimisation (PostgreSQL/MySQL), and cloud execution.
• Excited by the possibilities of integrating AI tools into your workflow to iterate quickly, combined with the discipline to rigorously check and ensure code quality.
• Clear communication skills, with a proven ability to translate complex technical constraints and architectural risks cleanly to non-technical stakeholders (compliance, operations, business development).
• A genuine curiosity about the green technology landscape. You won\u0027t be expected to dive into physical engineering or device-level software, so you don\u0027t need to be a hardware expert, we’re just looking for someone who shares our passion for getting clean energy into millions of homes.

🎁 Benefits

• Salary discussed on call with recruiters; flexible to match experience.
• Autonomy and ownership; open culture with co-owners.
• Recognized as a top employer with strong culture.
• Access to Octopus Employee Benefits portal.
• Opportunity to work on renewable energy tech at scale.
