• Develop systems using Node.js (TypeScript, NestJS) and/or Go.
• Design APIs, service boundaries, and communication protocols between cloud and on-site components.
• Implement secure authentication, authorization, and policy enforcement.
• Build asynchronous and event-driven workflows across cloud and on-prem environments.
• Ensure systems are observable by design, with meaningful metrics, logs, and traces.
• Own components end-to-end: design, implementation, deployment, monitoring, and reliability.
• Participate in architecture decisions across SaaS and agent layers.
• Debug and resolve production issues in distributed and hybrid systems.

Requirements

• 8+ years of professional software development experience.
• Strong backend experience with Node.js (TypeScript, NestJS).
• Proven experience building production-grade backend systems.
• Strong understanding of distributed systems, including failure modes and tradeoffs.
• Experience with cloud-native architectures and Kubernetes.
• Experience with AWS or another major cloud provider.
• Experience with SQL databases (PostgreSQL or similar).
• Experience with event-driven systems (Kafka, RabbitMQ, or similar).
• Strong understanding of security fundamentals (authentication, TLS, encryption).
• Hands-on experience with observability in production systems, including metrics, logs, and traces.
• Ability to work independently in an early-stage environment.
• Excellent debugging skills and strong production ownership.

Nice to Have

• Experience with microservices architecture.
• Familiarity with Docker and container orchestration.
• Knowledge of Agile methodologies.

What We Offer

• People-first management with minimal bureaucracy.
• A friendly company culture, proven by employees who choose to return.
• Flexible working hours.
• 29 days of PTO (18 working days per year plus all national holidays).
• 10 paid sick days.
• Full financial and legal support for independent contractors.
• Free English classes with native speakers or Ukrainian teachers.
