Senior Java Engineer, Retail

About AUTO1 Group: AUTO1 Group is Europe’s leading digital automotive platform, revolutionizing how consumers and dealers buy and sell cars online. As a high-growth tech pioneer, AUTO1 operates across multiple markets, powering flagship retail platforms like Autohero. Driven by a multicultural tech workforce of over 100 nationalities, our remote-first engineering squads utilize the latest cloud-native technologies to build cutting-edge applications, transactional systems, and financial tools that process millions of requests and streamline digital commerce across the continent.

Position Overview

We are seeking a highly autonomous, code-fluent, and architecture-minded Senior Java Engineer, Retail (f/m/x) to join our distributed Retail Engineering organization under a flexible remote-first framework, with core office hubs in Berlin, Germany and Kyiv, Ukraine. In this hands-on engineering seat, you will claim absolute full-lifecycle ownership, microservice design, and backend stability accountability for applications powering the consumer financing division of our Autohero retail website. Shifting completely away from routine non-technical data entry transcription, basic website theme layout styling, or simple office filing, you will run an active multi-threaded server architecture, database modeling, and distributed cloud routing laboratory—partnering closely with a distributed squad of skilled engineers and technical managers. This position requires a systems programming authority who writes enterprise application logic fluidly natively using Backend and Java ecosystem mechanisms, evaluates memory footprints and object-relational mappings cleanly within PostgreSQL, stands up continuous deployment pipelines using Jenkins Job DSL and Docker configurations, and guides proof-of-concept (PoC) or refactoring initiatives confidently to deliver robust, scalable digital banking and payment experiences.

Key Responsibilities

• Core Microservice Backend Governance: Design, implement, and maintain highly performant, distributed retail applications and core transactional microservices natively utilizing Backend architectural patterns.
• Full Lifecycle Software Delivery: Share comprehensive technical ownership across the full software lifecycle—encompassing deep discovery, architectural modeling, quality assurance instrumentation, deployment, monitoring, and live service maintenance.
• Cloud-Native Stack Optimization: Actively contribute to and scale our production cloud environments, writing robust code natively centered around Spring 5, Java 11+, AWS ECS, and AWS Lambdas .
• Refactoring & Architecture Leadership: Spearhead critical technical debt reductions, structural codebase refactoring, and proof-of-concept validation models to promote decoupled design patterns.
• Infrastructure and CI/CD Codification: Enforce stable software delivery pipelines, managing microservice containerization, build rules, and provisioning scripts via Docker, Jenkins Job DSL, and Terraform .
• Operational Monitoring & Tracing: Integrate advanced tracing, log aggregation, and real-time monitoring tools to ensure operational excellence and rapid bottleneck triage under high-traffic user volumes.
• Full-Stack Alignment: Balance system design complexities with efficient business logic flow across a specialized engineering split, dedicating roughly 80% to core backend logic and 20% to frontend views.

Required Skills & Qualifications

• Proven professional history operating as a Senior Java Developer, Back-End Software Engineer, JVM Architect, or closely related technical systems engineering capacity.
• Expert JVM and Cloud Fluency: Extensive, hands-on production history building scalable applications inside Java 11+ and the Spring Framework ecosystem.
• Demonstrated history designing and operating microservice infrastructures inside cloud-native settings, specifically including AWS networking, compute, or serverless services .
• Profound mastery of fundamental software design patterns and object-oriented principles (such as dependency injection/IoC, builder patterns, chain of responsibility, and strategy definitions).
• Production proficiency implementing continuous delivery flows, container configuration files, and relational database systems using Docker, Jenkins, and PostgreSQL .
• Location Context: Position operates under flexible remote guidelines open to qualified software developers collaborating with our international technical cells based in Berlin, Germany .

Preferred Strategic Indicators (Nice to Have)

• Prior experience developing high-volume digital consumer financing applications, payment gateways, or e-commerce transaction portals.
• Familiarity with frontend programming technologies, with hands-on exposure to TypeScript and React serving as an asset to facilitate full-stack alignment.
• Experience utilizing declarative infrastructure automation toolsets like Terraform to manage multi-tier cloud environments.

What We Offer

• Top-Tier European Digital Tech Perks: A highly competitive, experience-calibrated annual base salary structure, supplemented by valuable stock paths, modern technology equipment, and global rewards.
• Remote-first workspace autonomy with flexible working hours, offering an excellent work-life balance culture optimized for asynchronous execution.
• Highly Diverse International Culture: Direct integration within a multicultural tech powerhouse gathering more than 100 nationalities across international borders.
• Access to elite corporate tech gatherings, internal coding challenges, corporate hackathons, and vibrant company celebration events.
• Comprehensive health care assurance parameters, localized relocation or office hub pathways, and continuous professional development programs.
