What will your typical day look like?

No two days look exactly the same, but a typical day blends hands-on development with team support and technical leadership. You’ll spend time writing code on more complex parts of the system, reviewing pull requests, and helping unblock engineers. You’ll also connect regularly with product, design, and architecture to align on priorities and make key technical decisions.

Throughout the day, you’ll jump into problem-solving sessions, help guide approaches, and support team members through feedback and mentorship. You’ll balance staying close to the code with thinking ahead, making trade-offs, identifying risks, and ensuring the team is set up to deliver both now and over the long term.

Key Responsibilities:

• Technical Leadership - The Tech Lead provides technical direction in partnership with the Solution Architect, guiding decisions on architecture, tooling, and overall platform design. This includes maintaining strong engineering standards and promoting best practices suited to large-scale, collaborative systems.
• Team Collaboration -The Tech Lead fosters a collaborative and productive team environment, supporting knowledge sharing, mentorship, and strong team dynamics. They act as a key connector across engineering, product, design, and architecture to ensure alignment and progress.
• Problem Solving - Tech Leads guide the team through complex challenges, supporting thoughtful decision-making and a strong problem-solving mindset. They remain hands-on, spending roughly 40–60% of their time coding and contributing to key parts of the platform.
• Code Quality - Maintaining high code quality is a core responsibility. The Tech Lead drives consistent code review practices, provides clear feedback, and ensures alignment with development standards.
• Continuous Learning - The Tech Lead promotes continuous learning and encourages the adoption of modern tools and practices, including AI-assisted development, to support efficient iteration and innovation.
• Risk Management - They proactively identify and address technical risks related to scalability, reliability, and system design, ensuring issues are surfaced early and handled through sound engineering practices.
• Decision Making - The role requires strong technical judgment to make clear, timely decisions, balancing short-term delivery needs with long-term sustainability.
• Delivery Support - Tech Leads partner with Scrum Masters and product leaders to support planning and execution, helping break down work, prioritize effectively, and deliver consistent progress.
• People Development - The Tech Lead supports the growth of engineers on the team through mentorship, feedback, and ongoing development, helping individuals build their skills and take on new challenges.
