• Collaborate with Product, Design, and business stakeholders to translate requirements into technical deliverables.
• Mentor junior engineers and contribute to team-level planning, architecture, and standards.
• Write clean, maintainable, testable code with strong documentation.
• Evaluate and integrate third-party APIs and vendor services, especially in commerce, payment, or identity domains.
• Proactively identify areas of technical debt or scalability risks and drive improvement plans.
• Partner with QA and DevOps to ensure high performance, secure, and reliable delivery of software.
• Stay current with technology trends and advocate for thoughtful adoption within the team.

Required Qualifications

• 5+ years of professional software engineering experience, with a demonstrated focus on full stack development.
• Proficiency in at least one backend framework (e.g., Python/Django or Node.js) and one frontend framework (e.g., React).
• Strong understanding of REST APIs, database design (SQL/NoSQL), and AWS cloud services.
• Experience with CI/CD pipelines, observability tools, and agile workflows.
• Proven track record of owning and delivering complex projects with cross-functional impact.

Preferred Qualifications

• Experience in e-commerce, marketplaces, or fintech environments.
• Knowledge of authentication, security best practices, and performance optimization.
• Familiarity with GraphQL, event-driven architectures, or microservices.
• Prior exposure to the collectibles or sports enthusiast space.

Code-Writing Contribution

As a Senior Engineer, you will be expected to actively contribute production-quality code across multiple layers of the stack. Your work should reflect maturity in architectural thinking, a commitment to maintainability and performance, and a growing ability to balance technical execution with business needs.
