Senior Go Developer

20 years on the Romanian IT market and still growing.

Part of the HN Services Group, with offices in France, Spain, Portugal, and Luxembourg, HN Services Romania is about building real careers, not just filling roles.

What you’ll find here:

• Digital transformation projects with real impact

• A wide range of technical roles across modern and legacy technologies (yes, COBOL is still very much alive)

• Exposure to diverse industries and international envi ronments

• Continuous growth through our in-house software development training center (HN Training Institute)

💡We are currently looking for experienced professionals to deliver high-quality, stable, and resilient software solutions.

Responsibilities

• Design and build high-performance services: Design, develop, and maintain scalable APIs (gRPC and REST) powering core insurance services, taking ownership of complex services and their evolution.
• Own delivery at system level: Lead microservices and larger system components end-to-end — from requirements and architecture through implementation, deployment, and operational ownership in production.
• Contribute to technical direction: Provide input on technology choices, design patterns, and service boundaries; participate in architecture discussions led by Tech Leads and Architects.
• Mentor and elevate the team: Coach mid-level and junior engineers through design reviews, pairing, and constructive code reviews; raise the engineering bar across the team.
• Champion engineering excellence: Establish and enforce best practices in automated testing, observability (tracing, logging, metrics), CI/CD, and operational readiness.
• Lead in production: Act as a senior escalation point for complex incidents; drive root-cause analysis, reliability improvements, and cost/performance optimization.
• Ensure compliance and security: Embed security policies, coding standards, and regulatory requirements of the financial and insurance sector into design decisions from the start.

Qualifications

Must Have

• 8+ years of backend development experience, with 5+ years working with Golang in production
• Proven track record designing and evolving gRPC and REST-based APIs at scale, including ownership of complex service-level design decisions
• Expert-level understanding of distributed systems, microservices architectures, event-driven design, and cloud-native patterns
• Hands-on experience with containerization (Docker), orchestration (Kubernetes), and modern DevOps workflows, including production troubleshooting at scale
• Strong experience with PostgreSQL (data modeling, performance tuning) and message queues (e.g., Kafka, RabbitMQ)
• Demonstrated experience mentoring engineers and driving adoption of engineering best practices across a team
• Strong problem-solving skills and a passion for building clean, efficient, and maintainable systems
• Regular use of AI tools to improve productivity, automate or reduce repetitive work, support decision-making, and deliver higher-quality outcomes
• Ability to use AI tools responsibly by structuring effective prompts, critically validating outputs, understanding limitations, and taking ownership of the final result — and to guide others in doing the same
• Excellent English communication skills, including the ability to communicate design decisions to technical and non-technical stakeholders, and to thrive in a fast-paced, agile environment

Nice to Have

• Experience in the insurance, fintech, or broader financial services domain
• Deep familiarity with observability tooling (e.g., Prometheus, Grafana, OpenTelemetry, Jaeger)
• Experience with cloud platforms (e.g., AWS, GCP, Azure), ideally including cost optimization
• Knowledge of infrastructure as code (e.g., Terraform, Helm)
• Experience leading technical initiatives across multiple teams or contributing to platform-level decisions
• German language skills are a plus
