Senior Ruby on Rails Developer

Background

Over the past 18 years, Codeo has established itself as an integral technical partner for a number of high profile customers.

We've collaborated with customers on a number of amazing projects and have also been lucky enough to bootstrap successful product businesses along the way. We continue to actively support these products from an engineering and product design perspective.

In the last few years, we launched SendBoard - a Trello PowerUp that brings first class email support to Trello (see what Trello had to say about SendBoard on their blog).

Our customers value Codeo because we operate a highly competent and lean team. There is very little red tape. We don’t have layers of account managers and project managers between the customer and the people who actually add value (the folks that do the work). We’re lean in the context of size (we are a small team) but we also align our operations to the principles of lean manufacturing.

🚀 Codeo is on a mission to become more product focused.

We want to be invested in the products we help build. We want to leverage what we love and what we are brilliant at to make a positive impact on the way people live and work.

The Role

The job of delivering functional, beautiful, scalable, secure and user focused software is extremely challenging. There are so many angles and trade-offs to consider. For this reason, we are only considering experienced engineers for this role.

Location

This is a remote role. We have team members in 🇿🇦 South Africa, 🇳🇱 Netherlands and the 🇬🇧 UK. So, you’re free to operate from where you work best.

Perks

Choose your workstation - Work on what you’re most comfortable with, whether it be the top of the range PC or a high-end Apple MacBook Pro.
Flexible hours: Work-life balance is critical to us. To accommodate busy lifestyles, we don’t expect a rigid 9-5 commitment.
Remote Work: We’re geared to work from anywhere, so wherever is best for you, is best for us.
No ‘if this then that’ rewards: Everyone gets an annual 13th Cheque. We don’t do performance reviews.
Intentional Mastery: 10% of your work week is yours to invest in personal development.
Team Retreats and Events: We host regular team events to bring everyone together in a fun, exciting way.
Knowledge Sharing: We host weekly dev chat sessions to talk about new and interesting tools, frameworks etc.
Home Office Budget: We’ll provide a home office budget to kit out your home office with whatever equipment works for you (a standing desk for example).
