Expert Java Engineer
Ciklum
Role Description Ciklum is looking for an Expert Java Engineer to join our team full-time in Poland. As an Expert Java Engineer, become a part of a cross-functional development team engineering experiences of tomorrow. - Lead the Ciklum pod that our Client is bringing on to scale post-Series B engineering. - Deliver against two parallel workstreams: - Net-new feature engineering on the Java 21 / Spring Boot 3 platform. - Salesforce-to-microservices data and capability migration. - Act as the single throat-to-choke for the pod technically, and the principal technical interface to Client's VP Engineering and senior staff engineers. 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. - 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. Qualifications - 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. - 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. Benefits - 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. Company Description At Ciklum, we are always exploring innovations, empowering each other to achieve more, and engineering solutions that matter.
