Job Description

Job Summary:

As a Back End Developer at Phoenix, you will be responsible for designing, building, and maintaining robust server-side systems that power our internal platforms and customer-facing applications. Your responsibilities will include developing scalable APIs and services using Node.js, managing relational data with PostgreSQL and modern ORMs, contributing to CI/CD pipelines, and collaborating cross-functionally to deliver reliable, well-documented back-end infrastructure. The ideal candidate brings strong TypeScript fundamentals, solid experience with Node.js frameworks and database tooling, and a disciplined approach to version control and automated workflows. This role works closely with front-end engineers, product managers, and data teams and directly shapes the back-end architecture and API design at Phoenix.

Responsibilities:

•         Design, build, and maintain scalable RESTful and OpenAPI-documented APIs and back-end services for internal platforms and customer-facing applications.

•         Build and maintain automated CI/CD pipelines covering build, test, and deployment stages to ensure reliable, repeatable back-end releases.

•         Write clean, strongly-typed TypeScript across all back-end codebases, enforcing consistent patterns, code quality standards, and API contracts.

•         Collaborate with front-end engineers, product managers, and data teams to translate requirements into reliable, production-ready back-end features.

•         Manage feature development and bug fixes using Git branching workflows, participating actively in pull request reviews and code quality discussions.

•         Monitor and improve API performance, database query efficiency, and service reliability across back-end systems.

•         Partner with cross-functional teams to identify back-end bottlenecks and translate business requirements into scalable, well-architected solutions.

•         Write and maintain automated tests (unit and integration) to ensure service reliability and support confident refactoring.

•         Stay current with evolving back-end tooling, frameworks, and best practices, and advocate for improvements to service reliability and developer experience.

•         Document API design, service architecture, and deployment processes to support team onboarding and maintainability.

•         Contribute to back-end architecture decisions, including framework selection, data modeling approaches, and caching strategies.

•         Contribute to the evaluation and selection of third-party back-end libraries, cloud services, and infrastructure tooling.

•          Business partnership

•          Mentorship

Skills:

•         Strong proficiency in TypeScript with a deep understanding of type safety, generics, and modern ECMAScript patterns applied to server-side Node.js development.

•         Hands-on experience with one or more Node.js back-end frameworks including Fastify, NestJS, and/or Express; breadth across multiple framework styles is a plus.

•         Solid understanding of back-end fundamentals including RESTful design, semantics, authentication patterns (JWT/OAuth), and API documentation with OpenAPI/Swagger.

•         Familiarity with CI/CD tooling such as GitHub Actions, GitLab CI, or similar platforms for building and maintaining automated back-end pipelines.

•         Experience with automated testing frameworks for unit and integration testing of back-end services; a testing-first mindset is a strong plus.

•         Strong problem-solving and analytical thinking with the ability to translate ambiguous requirements into clean, efficient, and maintainable back-end implementations.

•         Excellent communication skills with the ability to discuss API design and architectural trade-offs clearly with both engineering peers and non-technical stakeholders.

•         Highly motivated, self-directed, and able to manage multiple priorities in a fast-paced, collaborative environment.

•         Experience with Redis and BullMQ for caching and job queue management is a plus; monorepo tooling and Docker/containerization experience also valued.

•         Curiosity and drive to explore new back-end patterns, database optimization techniques, and service reliability improvements.

Requirements:

•         Strong TypeScript proficiency with hands-on experience building and shipping production Node.js back-end applications.

•         Experience with one or more Node.js back-end frameworks: Fastify, NestJS, or Express; breadth across multiple frameworks is a plus.

•         Proven experience with PostgreSQL including schema design, query optimization, and managing migrations; experience with Prisma or Drizzle ORM required.

•         Hands-on experience designing and documenting RESTful APIs with OpenAPI/Swagger in a production environment.

•         Proven experience building and maintaining CI/CD pipelines and comfortable with Git branching and pull-request workflows in a collaborative codebase.

•         Familiarity with automated testing (unit and integration), monorepo tooling, and/or Docker/containerization is beneficial but not required.

Education:

•         BS in Computer Science, Software Engineering, or a related field, or equivalent practical experience.
