Backend Developer

Our customer is the leading omnichannel platform powering the digital transformation of the global contract catering industry. Their technology processes over $300 million in annual transactions across 3,500+ restaurants in 20 countries - and they keep scaling fast to cement the position as the category leader. They are trusted by the world’s most iconic brands, with the platform used daily in corporate canteens, universities and schools, airline lounges, stadiums, and hospitals.

We’re looking for a Backend Engineer to help build and maintain the core services that power the omnichannel ordering platform. You’ll work closely with frontend, product, and operations teams to deliver reliable, scalable APIs and backend systems that support fast, seamless user experiences. This is a hands-on engineering role focused on Grails and Python services running in AWS. You’ll be responsible not just for building features but for owning them in production - debugging performance issues, handling webhooks, optimizing queries, and ensuring uptime.

You’ll play a pivotal role in helping the team build scalable systems, drive technical excellence, and align engineering output with product outcomes. As the team continues to scale, the scope of this role will expand - creating clear opportunities to build and lead your own team. You’ll also have the chance to grow into senior leadership positions across the Development team with a progression path tailored to your strengths and ambitions.

Responsibilities:

From Code to Capability:

• Design, build, and maintain scalable backend services using Grails and Python, powering real-time ordering and payments
• Translate complex business logic into clean, testable code across APIs, background jobs, and data workflows
• Collaborate with Product, Frontend, and Ops teams to turn requirements into resilient backend solutions
• Optimize SQL queries and database structure for performance and scalability in MySQL
  
  

Build for Stability & Scale:

• Monitor system performance, logs, and uptime to proactively detect and resolve bottlenecks or errors
• Contribute to backend observability—improving alerting, tracing, and diagnostics for production systems
• Own key infrastructure components in AWS (EC2, RDS, S3, etc.) to support high-availability backend services
• Support continuous delivery by improving CI pipelines and deployment tooling
  
  

Support What You Build:

• Act as first-line technical responder for backend issues—triaging incidents, deploying hotfixes, and mitigating risk
• Partner with non-technical teams to explain backend behavior, limitations, and integration impacts
• Document system flows, edge cases, and debugging steps to strengthen platform knowledge and resilience
  
  

Requirements:

• 5+ years of experience building and maintaining backend systems in production, ideally with Grails, Spring Boot, or Python
• Writing clean, testable, and maintainable code — and caring about performance, scalability, and reliability
• Confidence working across the stack when needed, but happiest in the backend, designing APIs, optimizing databases, and scaling services
• Collaborating fluidly with Product, Frontend, QA, and Ops — you think in systems, not silos
• Ability to take ownership of the full lifecycle — from idea and architecture to deployment, monitoring, and support
• Communicating clearly, debugging calmly, and enjoying helping others understand how the backend fits into the bigger picture
• Fluency in English
• Interest in joining a high-performance culture, where you won’t be intimidated by the intelligence and work ethic of your peers - and are striving to make an incredible impact
• Experience working at pace and thrive under conditions of ambiguity, uncertainty and urgency
• Interest in helping shape the direction of the company and helping scale the leading omnichannel platform in the catering industry
• As a bonus - experience working with cloud infrastructure (AWS), CI/CD pipelines, and production observability tools
  
  

We offer:

• Competitive salary depending on your experience
• Professional development opportunities
• Study and practice of English: courses and communication with colleagues and clients from different countries
• Yoga classes
• Compensation package (paid vacation, sick leaves)
• Flexible working hours (from 9-11 to 18-20)
• Comfortable office in Warsaw or a possibility to work remotely
