Senior Backend Engineer
What You Will Do
Lead the technical design, architecture, and implementation of complex, high-throughput components for the core ad exchange platform.
Write exceptionally optimized, highly concurrent code (Go or Java), taking ownership of system performance where every millisecond counts.
Act as a technical pillar for the Dublin team: mentor mid-level/junior engineers, elevate code quality through PR reviews, and set engineering standards.
Take end-to-end ownership of critical services-from initial system design and agentic-assisted coding workflows, through to CI/CD deployment and production monitoring.
Partner closely with the Engineering Manager and product stakeholders to translate high-level business requirements into scalable, robust technical architecture.
Drive operational excellence by proactively identifying bottlenecks, optimizing infrastructure footprint, and leading complex incident resolutions.
What You Will Bring
5+ years of hands-on software engineering experience, with a strong focus on distributed backend systems.
Deep expertise in system-level or strongly typed languages (Go or Java), with advanced knowledge of concurrency, memory management, and performance profiling.
Proven track record of architecting and scaling high-throughput, low-latency applications.
Extensive hands-on experience with Cloud Computing platforms (GCP, AWS) and container orchestration at scale (Kubernetes, Docker).
Solid understanding of CI/CD pipelines (GitHub Actions, ArgoCD), IaC (Terraform), and modern observability stacks (Grafana, ELK).
Practical experience using and advocating for agentic-assisted development tools (Claude Code, OpenAI Codex) to increase team velocity.
Bonus: Deep domain experience in Ad-Tech, FinTech, High-Frequency Trading, or other environments handling tens of thousands of requests per second.
