Staff Engineer (Java)

What you'll do

• Develop scalable, low-latency solutions to support ad-serving operations with millisecond response times
• Architect and optimize multithreaded, non-blocking systems using frameworks such as Vert.x
• Collaborate with product teams to understand requirements, design technical solutions, and deliver high-quality features
• Ensure new features are robust, scalable, and aligned with system architecture principles
• Lead modernization of legacy Java/Tomcat systems by implementing best practices and upgrading frameworks
• Improve developer experience by integrating tools such as SonarQube, CI/CD pipelines, and testing frameworks
• Drive adoption of containerized and orchestrated deployments using Docker, ECS, and Kubernetes (EKS)
• Design and implement monitoring and observability systems using AWS-native and third-party tools
• Establish real-time alerting, logging, and distributed tracing systems to ensure platform health and reliability
• Leverage AWS infrastructure (ECS, EKS, S3, RDS) to build and optimize services
• Architect and implement scalable storage and caching solutions using Aerospike, Memcached, Redis
• Mentor and guide engineers, providing technical leadership and fostering engineering excellence
• Collaborate with cross-functional teams to prioritize features, address technical debt, and improve system reliability
• Address domain-specific challenges such as Real-Time Bidding (RTB), ad delivery, reporting, and data pipeline optimization

Requirements

• Strong expertise in multithreaded programming and non-blocking frameworks like Vert.x
• Proficiency in Java (modern frameworks such as Spring Boot are a plus)
• Experience designing and optimizing distributed systems for high throughput, low latency, and high availability
• Hands-on experience with caching (Memcached, Redis, etc) and databases (Aerospike, MySQL, Postgres, etc)
• Proven experience in designing and delivering new features aligned with product requirements and timelines
• Ability to translate business requirements into scalable and reliable technical solutions
• Experience with monitoring tools such as Datadog, Grafana, Prometheus, and AWS CloudWatch
• Strong knowledge of logging and distributed tracing tools (e.g. OpenTelemetry)
• Familiarity with developer productivity tools such as SonarQube, CI/CD pipelines, automated testing frameworks, and infrastructure-as-code solutions
• Proven ability to lead technical projects and mentor engineering teams
• Strong collaboration skills with product, engineering managers, and stakeholders
• 6+ years of software engineering experience focusing on distributed systems, feature development, and system modernization
• Hands-on experience with ECS, Kubernetes (EKS), Infrastructure as Code (Terraform), and advanced observability tools
• Knowledge of Real-Time Bidding (RTB), SSPs, DSPs, and ad delivery systems is a strong plus
• Familiarity with ad tech challenges such as latency optimization and reporting pipelines
• Strong knowledge of AWS infrastructure (ECS, EKS, Lambda, CloudWatch, S3)
• Understanding of container orchestration using Kubernetes, EKS, ECS
