senior founding engineer

Our client is a modern Church Management Software (ChMS) on a mission to equip churches with the tools they need to thrive. After a year of rapid growth, they’re at a critical juncture where a strong engineering team can be the difference between good and outstanding results. They’re looking for a Senior Founding Engineer with a doer attitude, love of state-of-the-art engineering practices, and the pragmatism required to deliberately break them when the need arises.

Our client is backed by a venture builder with a track record of producing some of Greece’s most successful scaleups (including industry-leading products). Working at a venture-backed company thus combines the upside, autonomy, and fast pace of startups with the security, resources, and guidance of a scale-up.

What You’ll Do

• Lead development across the full stack using Node.js, Vue.js, React and AWS
  

• Address customer pains with technical solutions that are proportionate to the value alleviating them will generate
  

• Break these solutions into deliverable increments that fit the budget that Product sets
  

• Balance delivering non-scalable solutions to unproven problems with building robust, scalable, and performant solutions after they are validated
  

• Make architectural decisions and improve how software is built
  

• Improve performance, stability, and scalability
  

• Mentor junior engineers and support team growth
  

• Review code and raise the quality bar

• Contribute to documentation and internal processes

Mindset

• You believe that anything that doesn’t generate value is waste
  

• You prefer being given problems to solve and the freedom to address them however you see fit within given constraints
  

• You dislike exhaustive specifications that leave no room for creativity
  

• You care deeply about your craft (clean git history, clear naming, minimal bloat) but are willing to break your own rules when it is deliberate and justified
  

• You are comfortable shipping non-functional code for experiments such as fake door tests
  

• You prefer real customer feedback over perfect implementations that no one uses
  

• You have an extreme ownership mentality: nothing is “someone else’s problem”
  

• You are customer-obsessed

• You are in it for the long term and want to own a piece of the upside
