Sr. Software Engineer

About the role

We are seeking a highly capable Senior Software Engineer to deliver high-quality, scalable software solutions across complex systems. This role requires a deep understanding of modern cloud-native technologies, ownership over technical delivery, and a collaborative mindset to influence both peers and product direction. You’ll work closely with engineers, product managers, and designers to build impactful features that serve our customers reliably at scale.

Responsibilities

• Lead and contribute to multiple concurrent engineering efforts across the full stack while integrating and/or orchestrating with AI tooling — from front-end interfaces to the backend services and APIs that power them
• Work both independently and collaboratively to drive technical solutions and deliver high-quality outcomes
• Design and build full-stack applications — responsive front-end experiences (React or similar) backed by well-architected services — with performance, scalability, and reliability considered at every layer
• Take ownership of features from planning through delivery: proactively estimate scope, lead implementation with minimal guidance, and provide thoughtful, high-quality code reviews that elevate the team's output
• Design performant, scalable, and reliable software, considering both functional and non-functional requirements across front-end, backend, and data layers
• Understand data flow, established patterns, and functional needs end-to-end to inform development
• Create a plan for your work by gathering information from your squad and the broader R&D organization
• Develop software that meets our internal standards of quality
• Make daily code contributions in small, manageable chunks, with continuous integration in mind
• Fix major issues, defects, and vulnerabilities in existing codebases, front-end or back-end
• Create and update unit and integration tests to ensure proper coverage of your contributions and maintain the coverage standard
• Proactively raise the bar for engineering quality by defining and evolving coding standards, workflow processes, performance benchmarks, and observability practices
• Leverage observability best practices to define monitors and alerts that ensure real-time insight into the operational health of production systems
• Diagnose and fix performance and optimization problems in legacy code, across the stack
• Partner with engineers and R&D stakeholders across teams to ensure effective collaboration and deliver results that move the business forward
• Teach and provide guidance to others in your area of expertise
• Participate in resolving, and sometimes lead the resolution of, after-hours production incidents
• Demonstrate your project work and product contributions

Qualifications

• 4+ years of professional software development experience across the stack
• Full-stack proficiency: hands-on experience building front-end applications with React or similar modern JavaScript frameworks, paired with experience designing and building the backend services behind them
• Solid foundation in cloud-native software architecture and development, including service design, data modeling, and persistence layers
• Fluency building and consuming REST, RPC, and GraphQL APIs
• Familiarity with technology stacks and architectures similar to Greenlight Guru's
• Exposure to or interest in AI-powered features in a SaaS product — experience with large language models (LLMs), generative AI APIs, or intelligent automation is a plus
• Skilled in writing unit and integration test suites
• Comfortable working within continuous integration pipelines and automation workflows
• Excellent written and verbal communication skills, with a strong emphasis on active listening
• Highly collaborative with exceptional interpersonal skills
• Data-driven mindset with a track record of using metrics to guide technical decisions and evolve systems over time
• Sharp problem-solving and troubleshooting instincts
• Genuine curiosity about how your code performs and creates impact in the real world

Benefits

• Supportive teammates and co-workers who care deeply about our mission
• Flexible Paid Time Off policy and working hours
• Remote-first culture
• Home Office stipend upon hire
• Multiple Health insurance options (vision, medical, dental)
• 401k (with company match)
• Equity Program Eligibility (based on role and/or tenure)
• Three months of paid maternity leave
• Disability insurance
