• Cloud experience with at least one of the major providers (AWS, Azure, or GCP)

• Solid database knowledge (PostgreSQL, MySQL, or similar)

• Secure coding mindset and awareness of potential risks

• Curiosity, autonomy, and ability to deliver in ambiguous environments

Nice to Have

• Experience building or working with ETL pipelines / data analysis

• Background or interest in cybersecurity

• Previous exposure to startup / scale-up environments

How They Work

• Remote-first, with a brand-new Dublin office for hybrid working if preferred

• Collaborative and transparent culture (flat structure, high trust)

• Regular team meetups and socials every 6-8 weeks

• Backed by strong leadership with experienced founders and advisors

Hiring Process

• Intro call → Culture fit with leadership → Technical interview (take-home or live) → CEO interview → References
