About the Position

Golang Developer

Ivano-Frankivsk, Ukraine | Wroclaw, Poland

We are seeking part-time (up to 100% availability) contractors to join projects requiring Senior/Middle Pro Go Developers. These projects center on building and maintaining high-performance microservices and distributed systems.

About the Project

Our projects focus on developing and maintaining high-performance microservices and distributed systems. We utilize a variety of technologies to ensure our systems are robust, scalable, and efficient.

Typical Tech Stack:

• Back-end: Go (Golang), gRPC, REST, Protobuf, PostgreSQL, Redis, Kafka/NATS/RabbitMQ, AWS SQS/SNS, ENT (ORM).
• Frameworks: Standard Library (net/http), Gin, or Fiber (for high-throughput APIs).
• Cloud & Tools: AWS/GCP/Azure, Docker, Kubernetes, GitHub + CI.
• AI Tools: Experience with AI integration tools and services.

Responsibilities

• Design and develop highly concurrent, scalable microservices using Go and TypeScript (for full-stack alignment).
• Optimize existing bottlenecks in the backend by implementing efficient Go concurrency patterns.
• Maintain high code quality through rigorous unit testing (using go test and testify) and code reviews.
• Maintain the existing code, refactor it, and build new features. New ideas are welcome, and there is an opportunity to improve the project with new approaches and architectural solutions.
• Backend development for a ticket sales platform, including integrations with third-party APIs, data mapping between different systems, payment processing with Stripe, and implementing and maintaining backend services.

Requirements

• Go Core Mastery: 5+ years with Go. Deep knowledge of Goroutines, channels, and memory management (GC tuning, avoiding leaks).
• Distributed Systems: Experience with Service Discovery, Circuit Breakers, and the Saga Pattern for distributed consistency.
• Data & DB Expertise: Strong SQL (PostgreSQL/MySQL) and NoSQL (MongoDB/Redis). Expert in GORM or raw SQL for high-performance queries; experience with ENT is a plus.
• Cloud-Native Skills: Strong hands-on AWS expertise - ability to set up and configure AWS infrastructure end-to-end (Lambda, EventBridge, SQS/SNS, IAM, etc.), plus Docker and Kubernetes orchestration.
• Third-Party Integrations & Data Mapping: Experience integrating external APIs and mapping/transforming data between different systems.
• English (B2+) & soft skills: Strong communication skills and ability to work effectively in a team.

Nice to Have

• Full-stack Awareness: Experience with TypeScript/React to better collaborate with front-end teams.
• AI/ML Integration: Building high-throughput Go wrappers for AI inference or agentic AI systems.
• Background in ticketing, live events, or other event-driven B2B SaaS platforms.
• Advanced Patterns: Experience with CQRS (Command Query Responsibility Segregation) or Hexagonal Architecture.
• Payment Processing: Experience with Stripe or similar payment gateways.
