Job description

We're looking for a Software Engineer and Tech Lead who combines strong hands-on development with the judgment to guide technical decisions. You'll own both the code and the direction.

In this role, you'll spend significant time writing production code—building robust, performant front-end systems with React and Next.js on AWS. You'll help set the standard for code review, ensuring the team maintains high standards while growing together. Beyond the code, you'll articulate a clear technical vision for our front-end architecture, helping the team understand the trade-offs behind our decisions and building confidence in the direction we're moving.

Purpose/Impact: (Duties & Essential Functions)

• Technical Leadership: Lead by example through high-quality code and clear technical judgment. Guide the team through architectural decisions, conduct collaborative code reviews, and mentor engineers on complex front-end problems.
• Requirements and Planning: Participate actively in planning meetings to understand product goals and user needs. Shape and verify technical requirements, identifying risks and trade-offs early, and pushing back when necessary.
• Full Lifecycle Ownership: Own features from conception through production—working with product and design to understand requirements, building and testing solutions, and supporting deployment and monitoring.
• System Reliability: Ensure the stability and performance of front-end systems through proactive monitoring, debugging, and addressing production issues. Drive improvements in build times, bundle size, and runtime performance.
• Cross-Stack Collaboration: Work across the full stack when needed, collaborating with backend and infrastructure teams to ensure cohesive solutions. Understand how front-end decisions impact overall system architecture.
• Documentation: Maintain clear technical documentation on architectural patterns, decision-making processes, and system behavior to help the team move faster and make informed decisions.

REQUIRED STRENGTHS AND BACKGROUND

• Experience: 5+ years of professional front-end development experience with demonstrated technical leadership.
• Additionally, broad technical knowledge across the full stack (backend, infrastructure, databases) and proven ability to execute effectively across diverse technologies and domains.
• Education: Bachelor's degree in Computer Science, Software Engineering, or related field (or equivalent professional experience).
• Specialized Skills: Hands-on experience with Next.js and AWS.
• Proven ability to lead code reviews, mentor engineers, and articulate technical trade-offs to both technical and non-technical stakeholders. Experience optimizing front-end systems for performance and scale.
