Senior Software Engineer (Python & Java)

About The Opportunity At Avenue Code, we are passionate about transforming businesses through technology. We are a leading end-to-end development consultancy for digital transformation across various markets, growing sustainably since day one. We believe that great results are born from strong relationships. Our team combines technical expertise, collaboration, and a welcoming approach to work that makes all the difference.

We're looking for a Senior Software Engineer to join a Troubleshooting team responsible for the stability and reliability of complex, cloud-based, production-grade systems. This is a hands-on backend role — you'll work close to real production issues, distributed systems, and architecture decisions, not just feature delivery. The role sits at the intersection of Python and Java/Spring Boot, so strong, recent, real-world experience across both is essential to succeed here.

Responsibilities

• Design, build, and maintain backend services and APIs using Python and Java/Spring Boot
• Investigate and resolve complex production issues across distributed systems, performing deep root cause analysis
• Build and evolve microservices architectures deployed in cloud environments
• Design, query, and optimize data models using PostgreSQL
• Participate in system design discussions and contribute to architectural decisions
• Collaborate closely with engineering peers to improve system observability, stability, and resilience
• Partner cross-functionally to define, implement, and troubleshoot integrations and platform features
• Take ownership of technical problems end-to-end, from investigation through resolution

Required Qualifications

• Strong, recent, hands-on experience building and maintaining real backend applications in Python
• Solid experience with Java and Spring Boot in production environments
• Practical experience working with PostgreSQL
• Proven experience designing and building microservices and RESTful APIs
• Experience working with cloud-based, production-grade systems
• Strong troubleshooting and root cause analysis skills in distributed, production environments
• Comfortable engaging in system design discussions and architectural trade-off conversations
• Ownership mindset and autonomy working through complex, ambiguous technical problems
• Advanced to Fluent English for daily collaboration with international teams.

Nice To Have Skills

• Experience with observability and monitoring tooling for production systems
• Familiarity with infrastructure-as-code or additional cloud services
• Exposure to building AI agents or agentic workflows
• Experience working in consultancy or multi-client environments
