Java Architect
Ciklum is looking for a Java Architect to join our team full-time in Poland. We are a custom product engineering company that supports both multinational organizations and scaling startups to solve their most complex business challenges. With a global team of over 4,000 highly skilled developers, consultants, analysts and product owners, we engineer technology that redefines industries and shapes the way people live. About the role: As a Java Architect, become a part of a cross-functional development team engineering experiences of tomorrow. You will work inside the embedded pod, owning service-level delivery against the Salesforce-to-microservices migration and net-new platform features. One of the two backend seats focuses on domain modelling and core service delivery; the other focuses on async messaging and event flows. The split is not rigid — both seats need both skill sets. Responsibilities: Own the technical roadmap and sequencing of the Salesforce → microservices migration. Define bounded contexts, the order of extraction, and the parallel-run / cutover strategy Set engineering standards for the pod — ADRs, code review bar, branching model, definition of done. Bring them; don't ask Client to write them Run the pod's delivery rhythm: planning, demos, retros, weekly engineering written update to Client Personally code 40–60% of the time. This is a hands-on lead role, not an architect-on-the-sidelines role Front the technical relationship with Client — RFC reviews, architectural debates, escalation point for blockers Own quality at the pod level: SLOs are met, test coverage holds, deployments don't break trunk Be the productivity multiplier on AI tooling for the pod — set the patterns for Copilot/Claude Code use, prompt libraries, AI-assisted code review Requirements: 8+ years building Java backend systems, with at least 3 years on Spring Boot in production Demonstrable monolith-to-microservices migration experience as the technical lead — not as a contributor. You can talk through the seams you cut, the data you split, the failures you handled Strong AWS architectural experience — VPC design, IAM, RDS PostgreSQL, ECS/EKS, SQS/SNS or equivalent Hands-on with async messaging architectures (Kafka, RabbitMQ, AWS SNS/SQS, or equivalent) including idempotency, ordering, and backpressure Track record of leading pods of 4–8 engineers in a fully remote or hybrid setting Native-level English — written and spoken. You will write the team's ADRs and design docs Desirable: Direct experience with Salesforce data extraction and migration to a relational target Working experience with AI agent frameworks — LangGraph, LangChain, CrewAI, or comparable Logistics, supply chain, B2B marketplace, or WMS / TMS domain background Prior technical-lead role in a Series B–C scale-up that grew from 5 to 50+ engineers Open-source contributions or technical writing that demonstrate the engineering bar What`s in it for you? Strong community: Work alongside top professionals in a friendly, open-door environment Growth focus: Take on large-scale projects with a global impact and expand your expertise Tailored learning: Boost your skills with internal events (meetups, conferences, workshops), Udemy access, language courses, and company-paid certifications Endless opportunities: Explore diverse domains through internal mobility, finding the best fit to gain hands-on experience with cutting-edge technologies Flexibility: Enjoy flexibility – full remote working possibilities Care: We’ve got you covered with company-paid medical insurance, mental health support, and financial & legal consultations About us: At Ciklum, we are always exploring innovations, empowering each other to achieve more, and engineering solutions that matter.
