About the role

  • Implement new features and functionality within Localize’s core product.
  • Build frontend features within our React/Redux single-page application.
  • Develop and maintain REST APIs with Node/Express/MongoDB that power the frontend application.
  • Own end-to-end delivery for product initiatives: discovery, technical design, implementation, testing, rollout, and iteration.
  • Translate ambiguous problem statements into clear execution plans, including trade-offs, sequencing, and measurable outcomes.
  • Be actively involved in product and architecture decisions.
  • Modernize and evolve an existing codebase: identify and prioritize tech debt, improve patterns and architecture, and deliver incremental upgrades without disrupting customer value.
  • Maintain a high engineering bar: readable code, solid tests, meaningful code reviews, and pragmatic documentation.
  • Collaborate with other remote engineers (including pairing where beneficial) and engage meaningfully in peer code reviews.
  • Diagnose and resolve production bugs throughout the development cycle, including incident response and measurable reliability improvements.
  • Collaborate closely with Product, Design, and Customer-facing teams to ship the right thing and learn quickly.
  • Improve platform fundamentals (architecture, observability, security, CI/CD, and developer experience).
  • Lead by example: drive alignment, coach others, and take accountability for outcomes.

Requirements

  • 6+ years of professional experience building, deploying, and maintaining production web applications.
  • Experience building complex single-page applications.
  • Strong frontend skills: modern TypeScript/JavaScript, React, state management patterns, accessibility, and performance.
  • Strong backend skills: Node.js + TypeScript, API design (REST and/or GraphQL), service architecture, and data modeling.
  • Experience writing, maintaining, and integrating REST APIs written in Node/Express.
  • Experience working with MongoDB and an understanding of common patterns and data structures, including schema design, indexing, and query performance.
  • Experience leading large development initiatives requiring collaboration and coordination with fellow engineers.
  • Proven ability to lead autonomously: scoping ambiguous work, writing short design docs, making decisions, and driving execution.
  • Enthusiastic about learning, working within, and architecting high-impact products.
  • Strong verbal and written communication skills, including clear stakeholder alignment and high-quality technical documentation.
Benefits
  • Competitive pay
  • Full benefits package
  • Emphasis on work + life balance
