Intetics; Poland; On-site; PLN 180,000 - 300,000; Full time

Job summary

Intetics Inc. is seeking a Go Application Architect to translate requirements into scalable architecture for distributed microservices, with a focus on performance, reliability, and maintainability.

You will design API contracts (REST/gRPC), choose data storage, integrate Kafka/RabbitMQ/NATS, and guide teams while balancing build vs. buy decisions.

This role requires 7+ years of software experience, strong Go skills, and proficiency with Docker, Kubernetes, and CI/CD in fintech-like domains.

Qualifications

• 7+ years of software development experience.
• 4-5+ years hands-on Go with goroutines, channels, context, memory model, concurrency.
• Education in Computer Science or related field.
• Experience in fintech/banking or regulated domains.
• Strong API design (REST/gRPC) with versioning and backward compatibility.
• Experience with distributed/microservice architectures and high-load systems.
• CI/CD practices and modern DevOps approaches.

Responsibilities

• Translate ambiguous requirements into a clear technical architecture.
• Design distributed, scalable, fault-tolerant microservice systems.
• Create robust API contracts with versioning and backward compatibility.
• Architect data storage strategies across relational DBs and NoSQL where needed.
• Design event-driven flows using Kafka, RabbitMQ, or NATS.
• Anticipate scalability and reliability risks and plan accordingly.
• Produce architecture docs (ADRs, specs, diagrams) for engineers and stakeholders.
• Mentor teams on best practices, Go idioms, and code quality.

Job description

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)
