1126 | Go Application Architect

Location: Poland; Romania; Lithuania; Latvia Intetics Inc. , a global technology company providing custom software application development, distributed professional teams, software product quality assessment, and “all-things-digital” solutions, is seeking a highly skilled and experienced Go Application Architect to join our dynamic team on a full-time basis. What You will do: - Translate ambiguous business requirements into a clear, well-structured technical architecture; - Design distributed and microservice-based systems that are scalable, fault-tolerant, and maintainable; - Make and justify architectural trade-offs (performance vs. complexity, consistency vs. availability, build vs. buy); - Design robust API contracts (REST/gRPC) with versioning and backward compatibility in mind; - Architect data storage strategies across relational and non-relational databases, including schema design and query optimization; - Design event-driven and asynchronous flows using message brokers (Kafka, RabbitMQ, NATS); - Anticipate scalability and reliability risks before they become production incidents, and design systems that account for load, failure modes, and observability from the start; - Produce clear architecture documentation (ADRs, technical specs, diagrams) that both engineers and business stakeholders can follow; - Guide and mentor development teams on best practices, code quality, and Go idioms without formally managing them; - Communicate technical decisions and trade-offs effectively to Product Owners, Solution Architects, and other non-technical stakeholders; - Evaluate new technologies, tools, and frameworks and assess their fit for the team's technical roadmap; - Balance hands-on coding with architectural oversight — staying technically credible while enabling other engineers to execute. Requirements - 7+ years of overall software development experience; - 4-5+ years of hands-on, production-level experience with Go, including deep understanding of goroutines, channels, context, memory model, and concurrency patterns; - Higher education in Computer Science (software development, etc.); - Extensive experience working with AI and the process of implementing/configuring it within a team; - Experience in fintech, banking, or other regulated/high-compliance domains; - Proven experience designing distributed, microservice-based, and/or high-load systems; - Strong expertise in API design (REST and/or gRPC), including versioning and backward compatibility; - Solid understanding of relational databases (PostgreSQL/MySQL) — schema design, query optimization, transactions; - Experience with message brokers (Kafka, RabbitMQ, NATS) and event-driven architecture; - Strong knowledge of containerization and orchestration (Docker, Kubernetes); - Experience with CI/CD pipelines and modern DevOps practices; - Golang (design of scalable, distributed backend systems); - Concurrency patterns in Go (goroutines, channels, sync primitives); - System design for high performance and maintainability; - CI/CD tools and pipelines (e.g. GitLab CI, GitHub Actions, Jenkins, etc.); - Understanding of system design principles: scalability, fault tolerance, security, observability (metrics, logging, tracing); - Strong communication skills — ability to explain architectural decisions to both technical teams and business stakeholders; - Experience conducting architecture reviews and writing design documentation (ADRs, technical specs); - Readiness to work from 9 till 18 CEST; - Readiness to practical task (live coding in Go) during the interview with the client. Would be a plus: - Experience with NoSQL databases (MongoDB, Cassandra, ClickHouse) or caching layers (Redis); - Exposure to cloud platforms (AWS, GCP, Azure) and cloud-native architecture patterns; - Experience with Domain-Driven Design (DDD) or Event-Driven Architecture; - Prior experience in a formal Architect, Staff Engineer, or Principal Engineer role; - Familiarity with additional languages (Java, Python, C++) for cross-team collaboration; - Experience integrating AI/LLM components into production systems; - Contributions to open-source Go projects or internal frameworks/libraries; - Experience with SRE practices (SLI/SLO, error budgets, incident response); - Relevant certifications (AWS/GCP/Azure architecture certifications).
