Senior Software Engineer, B-Corp | Tech for Good (Temporary, Maternity Leave Cover)

Leanpath is hiring a Senior Software Engineer for a temporary five-month assignment covering a teammate’s maternity leave. The role develops and maintains server-side Java features for a platform that turns kitchen-device data into food-waste reports and insights, while supporting product delivery, code quality, and production operations.

Responsibilities:

• Build and maintain server-side features in Java, working from a backlog the team has already planned
• Contribute to design discussions for the services that process and report on our customers’ food waste data
• Use AI coding tools such as Claude Code to get up to speed in our codebase quickly, and to speed up development, testing and documentation
• Write and tune SQL against our PostgreSQL databases, and pick up the occasional front-end ticket in Angular or AI related ticket in Python if you have experience in those areas
• Document your work so it is easy to hand back to the team when the assignment ends
• Take part in code reviews, giving and receiving clear, kind, and direct feedback
• Write automated tests (we use Kotlin for test automation) and hold your own work to a high quality bar
• Work within the team’s existing engineering standards and tooling, and suggest improvements where you see them
• Work with the Product Manager and fellow engineers to clarify requirements before and during development
• Help break product specifications down into well-defined work items and estimates
• Take part in sprint planning, backlog grooming, and retrospectives
• Troubleshoot and fix bugs and performance issues in the existing platform
• Help support the production environment on Google Cloud, including monitoring and responding to incidents alongside the team

Requirements:

• 7+ years of professional software engineering experience, with server-side Java as your primary language
• Strong server-side Java skills and a solid grasp of application architecture and design patterns
• Hands-on experience using AI coding assistants (Claude Code or similar) in your daily work, with the judgement to review and test what they produce
• Experience building and maintaining RESTful web services
• Strong relational data modeling and SQL skills
• A track record of getting productive quickly in an existing codebase and delivering with limited ramp-up time
• Experience with test automation, Docker, and CI/CD on an Agile team
• Clear, direct communication with fellow engineers and the Product Manager, including flagging blockers early
• Authorization to work in the United States
• A strong, authentic passion for using technology to solve global environmental challenges
• Micronaut experience is a plus
• Google Cloud experience is a plus
• PostgreSQL experience is a plus
