Senior Software Engineer

• Improve CI/CD, infrastructure-as-code, and DevOps practices
• Mentor teammates and collaborate with experienced specialists across several technical disciplines

Who We're Looking For
You're an engineer who:

• Takes genuine ownership and exercises sound judgment
• Holds well-reasoned technical opinions and can defend them

• Deep C# / .NET expertise
• Strong PostgreSQL skills
• Hands-on AWS experience
• Solid understanding of microservices, API design, and distributed systems trade-offs
• Experience integrating third-party APIs and external services in regulated environments
• Comfort with CI/CD, containerization, and modern DevOps practices
• Good judgment on when to build, when to buy, and when to simplify

Nice to Have

• Experience in FinTech, blockchain, or crypto
• Familiarity with KYC / KYT / AML workflows or providers
• Docker / Kubernetes (EKS, AKS)
• Infrastructure-as-Code (Terraform, Bicep)
• Event-driven architectures (Kafka, RabbitMQ, Service Bus)
• Observability tooling (OpenTelemetry, Datadog, Grafana)
• A strong interest in developer experience and security

What's on Offer

• Competitive salary and performance bonus
• Retirement and medical benefits
• Additional perks and allowances
• Hybrid working
• A collaborative, growing team of experienced engineers
• The chance to work on cutting-edge technology in a fast-paced environment
• A culture of innovation and continuous learning
