Senior AdTech Engineer (Remote, Full-Time) [TH038]

Responsibilities

- Build and scale the back-end components and infrastructure behind a programmatic advertising platform, developing low-latency, high-throughput services that process ad requests in milliseconds.

- Build proprietary AI agents for buying and distributing media, working closely with the team’s data scientist on content tagging and enrichment of ad requests.

- Integrate with third-party AdTech platforms and APIs, including OpenRTB, DSPs and SSPs.

- Act as a senior engineer within the team, overseeing work, running code and peer reviews, and guiding other engineers.

- Own a critical area independently while collaborating closely with the data scientist and guiding the wider engineering team.

- Apply architectural judgement and attention to detail in a real-time bidding environment where milliseconds and correctness matter.

- Help shape how agentic processes fit into the platform.

- Work flexibly within solid engineering disciplines, including GitOps deployments and a code-review culture.

- Take a problem-solving approach to building proprietary technology rather than simply following a specification.

- Prioritise careful improvement of a live, performance-critical platform without breaking existing functionality.

- Own the design and delivery of services or components end to end.

- Guide engineers through code reviews, mentoring and setting technical standards; line management is not required.

##

Requirements

- 5+ years of advanced Node.js back-end engineering experience.

- 3+ years of advanced experience building low-latency, high-throughput systems requiring millisecond response times and handling high request volumes. Relevant experience may include fintech, trading, payments, banking platforms, or real-time gaming or betting back-ends.

- 1+ year of proficient, hands-on experience building agentic AI for production, including LLM agents and working with a data scientist on models. You must have built AI agents , rather than simply used AI tools.

- 5+ years of advanced experience building APIs and third-party integrations.

- 2+ years of experience conducting code reviews and peer reviews and guiding engineers, or equivalent experience as a senior individual contributor who formally mentors engineers and owns review standards.

- 3+ years of advanced TypeScript experience. Strong modern JavaScript experience can be considered as a substitute.

- 2+ years of working experience with React.

- 2+ years of working experience with Google Cloud Platform (GCP). AWS or Azure experience can be considered as a substitute.

- 2+ years of working experience with Kubernetes and Argo CD for GitOps deployments. Kubernetes with Flux or Helm can be considered as a substitute.

- Senior Engineer/Architect-level capability with technical leadership experience and the ability to work alongside the CTO.

Nice to Have

- 2+ years of programmatic advertising experience, including OpenRTB, real-time bidding, DSPs and/or SSPs. Strong senior engineers with relevant low-latency systems experience may still be considered, as the domain terminology can be learned.

- Experience leading a project and owning the design and delivery of a service or component end to end.

- Basic Golang experience. Rust, Java, C++ or another performance-focused language can be considered as an alternative.

- 1+ year of working experience with Jenkins for CI/CD. GitHub Actions, GitLab CI or CircleCI can be considered as alternatives.

- 1+ year of working experience with Grafana for monitoring. Prometheus, Datadog or New Relic can be considered as alternatives.
