Job description

Easol is the leading all-in-one ‘experience commerce’ platform built to power experience businesses including festivals, wellness retreats, food and drink, sports and adventure trips. With Easol, experience businesses have complete control to drive more direct sales, retain more revenue, own their data and run their business on their terms.

Easol has deep roots in experiences. The platform was founded by former festival founders, Lisa and Ben Simpson in 2017, after the husband and wife team endured challenges and frustrations first‑hand while setting up and growing their own experience business including Rise, Europe’s biggest Snowsports and music festival, and Beyond Adventures, a series of adventure travel experiences in remote locations such as the Sahara desert and the Swedish archipelago.

About the role

Reporting into the Director of Engineering, the Senior Software Engineer will play a crucial role in developing our core services and the associated infrastructure, mentoring team members, and collaborating with product leadership to drive technical decisions.

• Collaborate with senior engineering management on technical strategy and roadmap planning
• Contribute to product decisions, working closely with product managers to shape feature development
• Identify and address performance bottlenecks and scalability challenges
• Participate in architectural discussions and help set engineering standards

How We Build Easol

• Our application is built on a Ruby on Rails monolith with Postgres and Redis, creating a solid, reliable foundation
• We believe in “boring Rails” – embracing Rails conventions and proven patterns that let us move quickly while maintaining stability and predictability
