Join Perlego as they are looking for a Senior Software Developer - Javascript / Typescript

About us

At Perlego, there's just over 100 of us working hard to make education accessible to all.

In this digital age, we believe that anyone should be able to learn anything at any time. Knowledge should be more accessible, not locked behind sky-high price tags.

Over the past 5 years our goal has been to support students across the UK & Europe to access quality books. The next stage of Perlego is two fold: 1) expand our support to students globally, and 2) build a product that goes beyond the book, a platform that helps students study smarter and more effectively.

What we’re looking for

A Senior Software Engineer with experience in Javascript, React, Node.js, AWS & TDD. You'll be joining our engineering team, working in a product squad with a data-driven mission to help our users have the best learning experience possible.

🔥What you’ll do🔥

You will co-lead a self-organising team in our product ecosystem providing technical leadership within the squad, solutioning and getting hands-on implementing the solutions to help your squad achieve its goal.

You will contribute to the design of distributed AWS cloud systems, Serverless Node.js application back-ends and React front-ends.

With your squad you'll bring these solutions to life, writing high-quality code utilising test-driven development (Jest /Cypress), continuous integration (AWS), code review (GitHub) and servant leadership practices.

You and your cross-functional squad will look after application features from inception to production working with customers and business stakeholders to bring them to life and support them in production.

You will take on scrum master responsibilities within the squad coordinating, planning, advising and facilitating with other squads & engineering management.

You will assist the team in implementing and monitoring engineering standards within the squad.

Why should you work at Perlego?

Apart from our mission, we foster a unique company culture championing collaboration, personal development, direct communication and mutual support. We’re proud of our 4.8 Glassdoor reviews and the fact that 97% of our team would recommend Perlego as a place to work.
