About the Role

This role is ideal for a backend-focused engineer who enjoys working on complex systems and is excited to help evolve a core platform during an important architectural transition.

• Build APIs, services, and data models that enable new product features and business capabilities
• Optimize system performance and ensure reliability as the platform continues to grow
• Build with observability and analytics in mind to support insights for internal teams
• Balance rapid iteration with long-term maintainability and strong developer experience
• Contribute to database design, infrastructure, and deployment workflows as needed
• Mentor and support other engineers, fostering a culture of high-quality engineering and collaboration

Ideal Candidate

• 5+ years of professional software engineering experience with a strong backend focus
• Backend development experience using Java, TypeScript (Node.js), or Python (experience with Java is a strong plus)
• Experience designing and maintaining scalable, production-grade systems
• Comfortable working in evolving codebases and helping guide architectural transitions
• Familiarity with cloud platforms (AWS or similar), APIs, and modern backend frameworks
• Strong problem-solving skills and the ability to work across technical and non-technical teams
• Experience with consumer, social, or marketplace products is a plus
• Experience working in start-up environments is a plus

Why Join

• Work on a high-growth, consumer-facing platform with real-world impact
• Influence core backend architecture during a key technical transition
• Collaborate with a tight-knit, experienced engineering team
• Competitive compensation and equity
• Comprehensive benefits, generous PTO, and a strong in-office culture
