Join FulmenFlux as a Senior Backend Engineer and become an integral part of extended engineering teams for leading international software companies. You’ll work on cutting-edge products used by millions while enjoying the stability and growth opportunities of our team extension model.
As a Senior Backend Engineer, you’ll be at the forefront of designing and implementing scalable backend services that process millions of requests daily. Your expertise will guide critical system architecture decisions for complex microservices ecosystems, where your choices directly impact product performance and reliability. You’ll work hand-in-hand with client engineering teams, participating in daily standups and sprint planning sessions that keep you connected to the product vision and business goals.
Your role extends beyond writing code—you’ll be a technical leader who mentors mid-level developers and maintains exceptional code quality through thoughtful code reviews. You’ll drive technical decisions that matter: choosing the right API design patterns, optimizing database schemas for scale, and selecting infrastructure that supports rapid growth. When production systems need attention, you’ll participate in on-call rotations (with additional compensation), ensuring the services you build maintain their reliability promises.
The technical challenges you’ll tackle are real and impactful. You’ll build distributed systems handling 100K+ concurrent users, design event-driven architectures using modern message queues like Kafka or RabbitMQ, and optimize database performance for datasets containing billions of rows. Your work will enable zero-downtime deployments through sophisticated CI/CD pipelines and create resilient systems that meet 99.99% uptime SLAs. This isn’t maintaining legacy code—this is building the future of software at scale.
