In this role, you will closely collaborate with the Product Owner to transform business requirements into implementation-level specifications that developers and QA can promptly execute. Your responsibilities include owning stories end-to-end, contributing code or reference implementations, and ensuring effective delivery without extensive oversight.Main ResponsibilitiesOwn architecture for product increments across client; convert business goals into concrete, executable stories with acceptance criteria and technical designs.Produce implementation-level specs, including:Description & Acceptance CriteriaAnalysisArchitecture Description (technical)Application scope & dependenciesTest coverage / Testing planRisks & mitigationsAuthor detailed contracts (REST endpoints, JSON Schemas, roles/permissions, predicates, enums) and keep them versioned and documented.Shepherd delivery: work with developers and QA to clarify, unblock, and review; ensure implementation matches the specification and passes tests.Contribute hands-on where needed (reference implementations, PoCs, skeletons, code reviews, migration scripts).Collaborate tightly with the Product Owner on business requirements and with senior architects who have in-depth system knowledge.Maintain traceable documentation (Confluence).Key Requirements8+ years in backend engineering with Java & Spring Boot; 3+ years in solution architecture for transactional, API-driven systems.Deep familiarity with Angular is essential (patterns, best practices, and components) to handle complex frontend/backend interactions.Strong experience with RESTful API design, JSON/JSON Schema, OpenAPI, and versioning strategies.Identity & access control: Proficient in Keycloak (or similar), RBAC, OAuth2/OIDC; comfortable defining roles, scopes, and authorization checks.Data & config: expertise in structured configuration management across environments; familiarity with feature flags and tenant/realm concepts.Documentation: excellent English communication skills; capable of translating business language into developer-ready details.Ownership & pace: operates independently, proactively addresses issues, escalates when necessary, and delivers.Nice to HaveExperience in multi-tenant or multi-realm setups; understanding regionalization/local market differences.Familiarity with case management domains, action availability predicates, and role-based action enablement.Experience with CI/CD tools (e.g., GitHub Actions/Azure DevOps/Jenkins), containerization, and observability (logs/metrics/tracing).Exposure to domain-driven design, ADR writing, and incremental refactoring in mature codebases.
