## Description

We are seeking an experienced Senior Software Engineer to join our product engineering organization. In this role, you will design and deliver backend systems that support a substantial base of business customers, contribute to key architectural decisions, and provide technical mentorship within a team of six engineers.

This is a position of genuine technical ownership. The successful candidate will influence engineering standards across the organization and play a central role in the continued modernization of our platform.

Technical environment

Our platform is built on TypeScript and Node.js, with React on the frontend, PostgreSQL as the primary datastore, and infrastructure hosted on AWS. The architecture is intentionally conventional, chosen for reliability and maintainability. Candidates should be aware that portions of the codebase are several years old; a component of this role involves leading its incremental modernization in a structured, pragmatic manner.

Key responsibilities

 * Design, develop, and deliver features end to end, from technical proposal through to production deployment
 * Conduct thorough code and design reviews that uphold and raise engineering standards
 * Lead the resolution of complex technical issues, including performance optimization, data migrations, and production incidents
 * Provide structured mentorship to mid-level engineers as a core component of the role
 * Contribute substantively to architectural decisions, which are made collaboratively across the team
 * Advise on technical feasibility and scope, including recommending against initiatives where appropriate
