You’ll help set technical direction beyond any single feature team – raising the bar for architecture, reliability, and operability across CRM data paths and product delivery – while staying close to the systems that serve ~130M active members and turn engagement into measurable outcomes for studios.

RESPONSIBILITIES:

• Guide technical alignment with Leads, Product, and teams such as CRM Ops and Connect to align technical bets with XLerate outcomes
• Mentor Engineers and technical leads across the CRM domain; unblock the hardest technical problems through design reviews and hands-on guidance
• Lead diagnosis and resolution of the highest-severity, cross-team Customer Incidents in the CRM space – coordinating CRM Ops, Connect, and partner squads, driving the technical fix, and leaving the system more operable than you found it
• Shape and set practical standards for how AI is used across XLerate delivery and product surfaces: raise the bar for safe, evidence-based use of AI in engineering (and, where relevant, member/studio-facing CRM workflows), without treating it as a side project.
• Identify, prioritize and land platform improvements that reduce systemic risk and accelerate delivery across the CRM domain
• Strengthen engineering execution through CI/CD, production readiness, observability, continuous improvement and through ways of working
• Set technical direction for large-scale platform migrations and integrations (including Gymsales → Glofox and cross-platform ABC integrations), including migration tooling, data cutover, and dual-run / coexistence strategies
• Shape webhook and third-party integration architecture that partner products and external systems rely on

QUALIFICATIONS:

• Bachelor’s degree in Computer Science or relevant field exp. preferred
• 8+ years of software engineering experience, with proven staff/principal-level technical impact required
• Deep systems design experience for distributed, data-intensive products that affect multiple teams and services
• Strong judgment on architecture trade-offs, production readiness, and long-term maintainability
• Solid understanding of the practical application of agile development methods in an Agile/Lean/Continuous Delivery environment
• Knowledge of modern Quality and Testing principles
• Strong written and verbal communication; comfortable influencing technical direction across teams, document architectural decisions and align senior engineering and product stakeholders
• Comfortable learning new technologies and systems
• Hands-on experience designing and delivering large data/platform migrations (tooling, cutover, rollback, and operability under dual-run)
• Experience establishing engineering standards across multiple squads

AND IT’S GREAT TO HAVE:

• Experience with Golang and/or Java services at scale
• Deep experience with large MySQL / relational data platforms
• Experience with no-SQL DBs (e.g. MongoDB)
• Prior CRM, marketing-tech, or audience/segmentation domain experience
• Experience with query federation / distributed querying systems
• Track record leading complex, multi-team incident or production-fix work (not only in-squad bugs)
• Practical experience applying AI in software delivery or CRM/marketing-tech products, with judgment on quality, privacy, and operability

378,000.00 – 450,000.00 PLN and and 68,000.00 – 75,000.00 EUR- annually.
