About The Position

We're looking for a Senior Software Engineer who thrives in a hands-on role. You'll be writing a lot of production code across our TypeScript-based stack while also contributing through thoughtful design, code reviews, and mentoring. This is not an ivory tower role - we need someone who enjoys solving problems at the keyboard, shipping features, and making pragmatic technical decisions. You'll bring the judgment and maturity to guide others, but you'll do so while actively building alongside them.

Requirements

Deep expertise in either backend or frontend engineering, with solid working knowledge of the other side
Proven track record of delivering complex features end-to-end in production systems
Deep experience with TypeScript or other modern application development languages such as Java, C#, or Python.
Familiarity with system architecture, API design, and scalable engineering patterns
Proficiency with databases (schema design, query optimization, performance tuning)
Ability to operate effectively in ambiguity, prioritize well, and balance speed with maintainability
Strong communication skills and empathy for both teammates and end users
Interest in leveraging AI to enhance user experiences, and openness to using AI tools to boost your own productivity

Responsibilities

Write high-quality, production-ready code across the stack, with focus areas that match your strengths (backend, frontend, or both)
Design and build scalable services, APIs, and user-facing features within our TypeScript monorepo
Integrate with external systems such as HRIS and ticketing platforms
Model data, design schemas, and optimize queries to keep our systems fast and reliable
Build for production with a focus on observability, monitoring, and testability from day one
Participate in design discussions, code reviews, and technical decision-making
Mentor teammates by sharing context, giving feedback, and helping them grow their craft
Collaborate closely with product, design, and engineering peers to deliver solutions that drive real business value
