Distributed Systems Architect

Quick Facts

• Role: Distributed Systems Architect

• Work mode: On-site or hybrid (3 days/week in office, 2 days remotely)

• Recruitment process: 1 phone interview + 2 meetings

Description

You will co-create the architecture of large-scale distributed IT systems, focusing on scalability, high availability, and security. The role includes defining architectural standards, translating functional and non-functional requirements into architecture decisions and technology choices, and maintaining architecture documentation (e.g., C4 diagrams, ADR, interface specifications). You will also plan modernization and decomposition of existing modules, reduce technical debt, and mentor project teams.

Responsibilities

• Design distributed, scalable, highly available system architecture and evolve existing solutions

• Define and enforce architectural standards, rules, and patterns across project teams

• Analyze functional and non-functional requirements and convert them into architecture decisions and technology selection

• Create and maintain architectural documentation (C4, ADR, interface specifications)

• Plan and supervise modernization and decomposition of existing system modules

• Lead architecture and code reviews; identify technical risks and manage technical debt

• Design for resilience, security, observability, and continuity, considering regulatory requirements (NIS2/KSC, GDPR/RODO)

• Collaborate with development, DevOps/platform, security teams, and the customer

• Participate in estimates and preparation of architecture-related proposals

• Provide mentoring and expert support to project teams

Requirements

• Minimum 6 years of software development experience in IT; at least 3 years as an architect or technical lead for distributed, highly available systems

• Strong system architecture knowledge: architectural styles and patterns (microservices, modular monolith, event-driven architecture/EDA, SOA)

• Domain-Driven Design and domain decomposition into services

• Knowledge of distributed systems fundamentals and data consistency design

• Experience with synchronous and asynchronous communication: REST, gRPC, API-first, message brokers and streaming platforms (Apache Kafka, RabbitMQ or equivalent)

• Experience designing fault-tolerant systems

• Practical knowledge of containerization and orchestration

• Observability expertise: OpenTelemetry, distributed tracing, metrics and logs

• Ability to design security at the architecture level

• Knowledge of Infrastructure as Code, CI/CD, and GitOps

• Knowledge of relational and non-relational databases

• Ability to analyze non-functional requirements

• Strong architecture documentation skills using C4, ADR, and UML

• Excellent knowledge of at least one backend language/ecosystem: Java or C#/.NET
