Junior Backend Engineer

About the role

We are recruiting for a large, privately owned European technology company operating multiple high-traffic consumer platforms across several markets. Their products are used daily by millions of users, and engineering and data are central to the company’s strategy.

As a Mid-level Backend Engineer, you’ll build and operate robust, scalable backend systems at the heart of how data is structured, processed, and used at scale. You’ll take meaningful ownership of services that must remain fast, secure, and highly available - even as traffic patterns shift, data volumes grow, and requirements evolve across multiple markets and platforms.

What makes this role a compelling challenge is the combination of scale and complexity. Availability and performance are daily expectations, and pragmatic engineering choices - API design, data modeling, reliability patterns, and operational readiness - directly impact a very large user base. You’ll be part of a team that values ownership, clear standards, and measurable improvements to reliability and engineering quality.

We work in a hybrid model (four days per week in the office, one day remote) and offer competitive compensation and benefits.

In this role you will:

• Build, evolve, and operate backend services that power a large-scale consumer platform, with a strong focus on high availability, low latency, and predictable performance under heavy load.
• Design and implement well-structured APIs and service boundaries, balancing speed of delivery with long-term maintainability.
• Own components end-to-end: from design and implementation through deployment, monitoring, and incident follow-up, with a mindset of continuous improvement.
• Use AWS as a core part of your toolkit, making thoughtful decisions around scalability, resiliency, security, and cost.
• Improve reliability and observability through testing, instrumentation, alerting, and runbooks, and by reducing recurring operational issues.
• Collaborate closely with engineers and partners to clarify requirements, make trade-offs explicit, and deliver changes safely in a complex environment.
• Help strengthen the engineering function by contributing to shared patterns, documentation, and everyday practices—and by supporting junior engineers through reviews and knowledge sharing.

The skills you bring:

• Strong backend engineering experience in C#, building and operating production-grade services.
• Hands-on experience with AWS in real-world environments (designing, deploying, and running cloud-based systems).
• Experience building secure, scalable APIs and service-oriented architectures (microservices experience is a plus, but not required).
• Solid understanding of data stores and data modeling (e.g., PostgreSQL and/or MySQL); experience with streaming/event-driven systems (e.g., Kafka) is a plus.
• Comfort with containers and modern delivery practices (Docker, Kubernetes, CI/CD) and an appreciation for automation and repeatability.
• A software engineering mindset grounded in good practices: testing, code review, observability, and operational excellence.
• Confidence working with ambiguity, taking ownership, and making pragmatic decisions with incomplete information.
• Clear, collaborative communication and a respectful approach to working with different perspectives and backgrounds.

We welcome applicants from a wide range of backgrounds and experiences. If you’re excited by the challenge and can see yourself growing into the role, we encourage you to apply even if you don’t match every requirement perfectly.
