About Swisstech

Role Description

Swisstech is hiring a Senior Backend Engineer , a top-tier builder ready to design and implement core platform systems from scratch. This is not a junior or mid-level role. We’re looking for someone who already thinks like a system architect , but still writes clean, maintainable code with care and speed.

You will own entire systems, collaborate closely with a senior engineering team, and help define the architecture, technical standards, and backend foundation for a next-gen financial platform.

You will be responsible for building secure-by-default , scalable, multi-tenant aware , and observable backend services capable of powering mission-critical, global fintech operations.

If you're looking for a high-impact role where your technical decisions will shape the future of our stack, culture, and product, this is it.

Minimum Qualifications

• 5+ years of hands-on backend experience building real-world systems
• A bachelor's degree in computer science or a related field.
• Deep proficiency in .NET Core (C#) — this is our primary backend language
• Solid understanding of relational databases, especially PostgreSQL (or SQL Server)
• Experience with Redis for caching, deduplication, and lightweight queues
• Comfortable designing and implementing event-driven systems with Kafka , RabbitMQ, or similar message brokers
• Understanding of multi-tenant architecture: data isolation, config overrides, modular logic
• Experience working with Docker for development and deployment (Kubernetes experience is a plus)
• Familiarity with CI/CD tools like Azure Pipelines or GitLab CI
• Experience instrumenting production systems with logging (ELK or Loki) , metrics (Prometheus/Grafana) , and distributed tracing
• Strong system design instincts: you can design secure, fault-tolerant, and scalable services from scratch
• You write clean, testable, observable code that works in production — not just POCs
• You're able to own complex systems independently in fast-moving or ambiguous environments

Highly preferable

• Exposure to Go or Rust
• Experience in fintech , crypto , Lending , payments , or compliance-heavy platforms
• Familiarity with HashiCorp Vault or secure key management tools
• Built or scaled event-based , microservice , or multi-tenant SaaS platforms
• Experience with KYC/AML , audit trail, or PII-sensitive systems
• Background working in early-stage product teams (A→Z)
