This is not a purely managerial role: you will be expected to be in the code, lead by example, and bring practical engineering judgment to every discussion.\nYou will operate at the intersection of individual contribution and technical leadership. You will partner closely with architects to shape system-level decisions while remaining the most knowledgeable voice in the room about what is actually happening in the codebase day to day.\nResponsibilities include:\nHands-On Development\nWrite, review, and own production-quality code as a day-to-day activity - this role maintains a meaningful individual-contributor output.\n\nDrive code quality through TDD, clean architecture principles, and rigorous code reviews.\n\nSet and enforce engineering standards across the team including CI/CD pipelines, branching strategies, and release practices.\n\nArchitectural Collaboration\nEngage actively with solution and enterprise architects to shape backend architecture, API design, event-driven patterns, and cloud-native deployment strategies.\n\nTranslate high-level architectural decisions into actionable technical designs the team can implement with confidence.\n\nProduce clear solution design documents, API specifications (OpenAPI/REST), and integration workflow diagrams.\n\nChampion microservices, event-driven, and clean/hexagonal architecture patterns where appropriate.\n\nBe familiar with SQL and noSQL Databases (Postgres and MongoDB) and have in-depth experience with high-volume transaction applications.\n\nTeam Leadership\nLead, mentor, and develop a small team of engineers - building capability, confidence, and a culture of technical excellence.\n\nRun Agile ceremonies: sprint planning, retrospectives, and backlog grooming; work closely with product and delivery stakeholders.\n\nAct as the primary technical escalation point within the team, unblocking engineers and resolving ambiguity quickly.\n\nManage deliverables and coordinate with cross-functional teams including QA, infrastructure, security, and operations.\n\nReliability & Observability\nBuild and maintain observability tooling - dashboards, alerting, and runbooks - to ensure production health and fast incident response.\n\nLead incident response, root cause analysis, and preventive improvements.\n\nChampion DevOps practices: infrastructure as code, automated deployments, and shift-left testing.\n\nQualifications\nExperience & skills\n10+ years of software engineering experience with demonstrable hands-on coding in recent roles.\n\nProven track record leading small engineering teams (2-8 people) end-to-end from design to production.\n\nStrong backend engineering background: Java / Spring Boot, with modern cloud-native patterns.\n\nPractical experience with event-driven architectures and messaging systems (Apache Kafka, SQS/SNS, RabbitMQ).\n\nCloud platform expertise: AWS (ECS/EKS, Postgres RDS, ElastiCache, network configuration).\n\nAPI design and security: REST, OpenAPI/Swagger, OAuth 2.0, JWT.\n\nContainerization and orchestration: Docker, Kubernetes.\n\nCI/CD pipelines: Jenkins, GitHub Actions.\n\nObservability tooling: Splunk, Grafana or equivalent.\n\nStrong communication skills; ability to produce design documents and engage non-technical stakeholders confidently.\n\nExperience in regulated or compliance-sensitive industries (iGaming, fintech, media, or similar) is advantageous.\n\nNice to have\nHands-on experience with WSO2 API Manager or similar API gateway / IAM platforms.\n\nFamiliarity with PAM (Player Account Management) or iGaming platform concepts.\n\nInfrastructure-as-code with Terraform and Helm.\n\nAWS Certified Solutions Architect, Azure certifications, or Confluent Kafka certification.\n\nAdditional Information\nWhy would you enjoy working with us at Light & Wonder?\nCompetitive benefits, an open and supportive environment as well as a modern and exciting workplace.\n\nThe opportunity to interact with global teams on a regular basis and the possibility to switch teams and projects as you and our business continues to develop and grow.\n\nExciting projects with opportunities for creating positive change to our game engineering ecosystem.\n\nAnd if that is not enough; you will get to enjoy astunning work location and flexible working whilst we provide you with the guidance and development skills you need to progress quickly and enhance your career.\nLocation Athens, Greece or Sofia, Bulgaria.
