Applications closed

Plek is a widely used online collaboration and communication platform (SaaS) that’s looking to break new ground with cool new products that help improve productivity and engagement at our clients’ companies. Our backend team needs you to help build those new features in NestJS, as well as rebuilding parts of our older codebase (currently in NodeJS). We’re looking for someone who knows how to write clean code, isn’t afraid of a challenge, and yet understands refactoring always needs to be balanced with commercial pursuits.

Job Description

Hence, we seek a seasoned senior backend engineer adept in either NodeJS or NestJS (and then willing to learn the other one) to lead the development of pivotal functionalities for our SaaS product. Your role will guide a collaborative team towards robust, high-quality software solutions, elevating Plek's code standards, focused on maintainable, well-tested code in an agile and dynamic work environment.


- Lead development using NodeJS, NestJS, and other technologies for our SaaS product's key features.

- Advocate and implement code integrity, scalability, and maintainability best practices, particularly within NestJS.

- Mentor developers within the NestJS ecosystem and engage cross-departmentally to ensure seamless feature integration and deployment.

- Conduct in-depth code reviews, providing constructive feedback to enhance NodeJS- and NestJS-based code quality.

- Optimize application efficiency and resolve performance constraints leveraging NestJS capabilities.

- Stay updated on industry trends and technologies to refine NestJS-based development methodologies.


  • - Hold a degree in Computer Science, Software Engineering, or relevant field, or possess equivalent work experience.

    - Extensive TypeScript/JavaScript backend development expertise, particularly in NestJS.

    - Demonstrated leadership in backend software projects, emphasizing NestJS proficiency.

    - Strong grasp of software engineering principles, design patterns, and industry-leading practices, especially within NestJS.

    - Proficiency in NodeJS / JavaScript (ES6+), unit testing frameworks, Git, and modern development tools in NestJS context.

    - Track record in secure software product development..
