Responsibilities

• Initiate and lead engineering projects from design through production, owning shipped work and maintaining it over time.
• Own and review project briefs and technical designs for complex features and systems, making technical decisions and fostering cross-team alignment.
• Coordinate across teams and ensure the team's work fits into and improves broader systems.
• Write clean, well-tested code with clear, extensible interfaces while avoiding undue technical debt.
• Identify friction and improve how the company designs, builds, tests, and operates software.
• Evaluate technologies and tradeoffs systematically, and extend the team's understanding of its technology stack to meet changing requirements.
• Mentor engineers through pairing, reviews, and thoughtful feedback.
• Collaborate with product, design, customer engineering, and other teams to identify technical blind spots, clarify ambiguity, and deliver iteratively.
