  • Mentor and develop junior engineers through design, collaboration, and communication

  • Drive process improvements and architectural changes to cultivate a first-class developer experience on the team

  • Create first-class testing automation to ensure high-quality deliverables

  • Leverage AI coding tools (e.g. Copilot, Cursor, Claude) as a force multiplier in your day-to-day development — and actively share learnings and best practices with the team

  • Work with leadership within and external to the team to understand technical requirements, drive user experiences, and influence business decisions based on technical feasibility

  • Independently manage and complete complex projects, and be accountable for their outcomes

  • Work with internal and external clients during the entire  lifecycle

  • Be empowered to make decisions and ensure on-time, high-quality deliverables

  • Strong proficiency in Python, and experience with frameworks such as Flask, LiteStart, FastAPI

  • Experience building and operating Service-Oriented Architectures

  • Experience working with front-end technologies like HTML, CSS, JavaScript, React, and modern frameworks

  • Experience working on front-end components at scale

  • Hands-on experience using AI-assisted development tools to accelerate coding, debugging, test generation, or code review, with a practical sense of where they're most and least reliable

  • Knowledge of caching technologies, database systems, and proficiency in SQL 

  • Experience working with behavioral and product data to validate hypotheses, design and interpret experiments, and connect engineering decisions to measurable customer and business outcomes

  • Experience integrating with third-party platforms and services

You are:

  • A Strategic Technical Leader: Adept at balancing short-term priorities with long-term technical vision and objectives

  • Customer-Centric: Committed to enhancing the customer experience through thoughtful and innovative solutions

  • Empathetic and Inclusive: Foster a collaborative, respectful, and accountable team culture where diverse perspectives thrive

  • Solution-focused: Approach challenges with a forward-thinking mindset, ensuring momentum is maintained

  • AI-Augmented: Comfortable integrating AI tools into your development workflow and thoughtful about their tradeoffs — you know when to trust the output, when to push back, and how to get the most out of them without sacrificing quality

  • Data-Informed: You instrument your own work, define measurable success criteria, and use behavioral data and experimentation results to validate decisions and surface improvements

  • Results-driven: Proven ability to deliver impactful, high-quality features that align with business and technical goals

Bonus Points:

  • Experience with AWS, Docker, or other cloud systems

  • Experience with front-end optimization

  • Experience decomposing monolithic systems
