## Job description

We’re currently looking for a Senior Backend Engineer with strong PHP expertise and solid Node.js experience to join the Enterprise API & Platform API Team.

This is a hands-on engineering role focused on modernizing and scaling a large PHP-based backend. You’ll have the opportunity to work on the evolution of a monolithic architecture into more modular, service-oriented components while improving code quality, testing, performance, and reliability.
You’ll work in a remote-first, globally distributed team, collaborating closely with Product, Platform, and Engineering teams. Your technical decisions and architectural thinking will have a direct impact on how the platform evolves and scales.

Employment Type: UoP
Location: Warsaw | Remote

### WHAT YOU’LL DO:

- Develop a deep understanding of an existing PHP monolithic codebase and progressively extract functionality into modular, service-oriented components.

- Design, build, and maintain scalable, testable, and reusable backend services using PHP and Node.js.

- Design and maintain robust RESTful and GraphQL APIs.

- Lead and contribute to refactoring initiatives focused on performance, readability, maintainability, and scalability.

- Build, deploy, and operate backend services on AWS, including Lambda and API Gateway.

- Write and maintain unit and integration tests to ensure reliability across releases.

- Use AI coding tools effectively while critically reviewing, validating, and improving AI-generated code.

- Identify technical risks, performance bottlenecks, and opportunities for improvement across the platform.

- Clearly communicate technical decisions and trade-offs through documentation and short video walkthroughs.

- Collaborate effectively within a remote, async-first, cross-timezone environment.

### WHAT WE’RE LOOKING FOR:

- 5+ years of professional backend engineering experience.

- Expert-level PHP experience, including work on enterprise-grade production systems.

- Strong hands-on experience with Node.js.

- Experience refactoring or decomposing monolithic architectures into modular services.

- Strong knowledge of backend architecture and API design, including REST and GraphQL.

- Hands-on experience with AWS, particularly Lambda and serverless architectures.

- Experience writing testable code and maintaining automated test suites.

- Experience with AI-assisted development tools such as GitHub Copilot, ChatGPT, Claude Code, or Cursor, with the ability to critically review and refine generated code.

- Strong written and spoken English.

- A proactive, self-directed approach and the ability to work independently, communicate clearly, and unblock yourself in a remote environment.

### WHAT YOU’LL GET

- Great people — a talented, collaborative, and friendly international team.

- Learning & development — access to training and learning resources to support your growth.

- 26 days of vacation plus floating and company holidays.

- Wellness & work-life balance — wellness benefits and paid parental leave.

- Comprehensive insurance package covering medical, life, and business travel.

- PPK — participation in Poland’s Employee Capital Plan.

- Equity — stock options as part of the company’s equity-sharing program.

- Work-from-home stipend to help you create a comfortable home office.

IF THIS SOUNDS LIKE YOUR NEXT CHALLENGE, FEEL FREE TO APPLY!

**Live in Easysoft’s hiring system.** Read from the company's own applicant tracking system, not reposted from a job board — so it's a real, open requisition rather than an ad that outlived the role.

We remove it as soon as it disappears at source.
