Senior Backend Engineer

About the Role: Bïrch (formerly Revealbot) is a mighty toolbox for all the things creative and growth marketing teams do—content creation, collaboration, and ad campaigns. We are seeking a Senior Backend Engineer to join our remote-first team. In this role, you won't just maintain existing systems; you'll help build new products, shape architecture, and contribute to key technical decisions across our dual-language backend (Ruby on Rails and Go).

What You'll Do

• Act as the sole backend engineer in a small product squad, owning large features and full products from idea to release.
• Write production-ready code in Ruby and Go for new features and improve existing systems.
• Handle and triage production issues across different systems, taking full ownership.
• Develop and maintain integrations with ad platforms like Meta, Google, TikTok, and Snapchat APIs.
• Define and improve engineering standards, from coding and testing to monitoring and CI/CD pipelines.

What You Bring

• Deep expertise in Ruby and Ruby on Rails, along with confidence in working with Go (roughly 50/50 split).
• Expert-level knowledge of PostgreSQL, understanding databases at scale (indexing, query optimisation, partitioning).
• A DevOps mindset, comfortable taking responsibility for how code runs in production (EC2, Docker, Terraform, Ansible).
• Pragmatic relationship with AI tools and strong skills in performance optimization and testing.
• Bonus: Experience with AWS Stack and working experience in the AdTech/MarTech industries.

Benefits

• 38 days of paid time off annually and a $2000 annual holiday travel bonus.
• Full health insurance (Alan or SafetyWing) and fully paid parental leave (3 to 6 months).
• $2000 annual L&D budget and a $2000 annual bonus for team meetups.
• Laptop budget for powerful gear and a co-working space budget.
• Fully remote work flexibility across eligible European countries (Spain, Portugal, Germany, Netherlands, Serbia) or hybrid in Barcelona.
