About Charlie

We’re Charlie, and we’re on a mission to equip thousands of startups and ambitious small businesses to deliberately craft their culture every day.

Charlie builds progressive HR solutions for startups and ambitious small businesses to successfully manage their teams and intentionally craft their culture.

We’re looking for a Software Developer to join our growing product development team – and help us to fulfil our product vision implementing great software.

What is a "Software Developer III"?

We have a career progression framework that includes Individual Contributor and People Manager tracks. An IC1 is a junior developer, an IC4 is a senior developer, and IC levels 2 and 3 cover that middle area that is often only labelled "Software Developer".

As a Software Developer III you should be able to:

Make good technical decisions to deliver sound solutions

Communicate and partner effectively across functions

Understand the importance of success metrics for projects

Demonstrate knowledge of industry trends

In this role you will:

Build and improve Charlie, a Rails app using the latest versions of Rails and Ruby

Use our design system to ship functional and beautiful features that look and feel like Charlie

Be part of a cross-functional team with other developers, designers, product managers

Work with developers of all experience levels to ensure you’re both learning and sharing your knowledge

Feed into product and business decisions and make your mark on Charlie

A typical week will include:

Shipping updates as soon as they're ready, often multiple times a day

Working with other developers and reviewing code to maintain a high code quality and share knowledge across the team

Collaborating with your cross-functional teammates, such as Product Designers and Product Managers

Team and company-wide meetings where we discuss strategy, provide updates and share feedback


You must have:

Professional experience with Ruby and Rails, or a similar language/framework combo

Knowledge of relational databases

Experience writing automated tests

A strong understanding of how the web and web applications work

A track record as an individual contributor

An enthusiasm for collaboration and helping others

Excellent communication skills and a positive attitude

Let us know if you have: (all of these are desirable, but none are required)

Experience working on similar SaaS products

Worked with a design system

Familiarity with security (eg. ISO27001)

Worked on applications hosted on Heroku

Our tech:

Ruby: Rails, Sidekiq, RSpec, Devise

Frontend: our design system is built with Ruby, JavaScript and Sass

Infrastructure: Heroku, PostgreSQL, Redis, Heroku CI, Stripe API

We will still consider applications even if you don't meet every single one of the above requirements, so don't be put off if you don't match them absolutely perfectly!

This is a permanent full-time role. We cannot offer visa sponsorship and you must be able to work in the UK.
