What the job involves
- The Senior Software Engineer will join the Nexxen DSP Software Development team as a senior technical contributor and trusted leader on mission-critical, high-throughput services
- Our DSP processes billions of real-time transactions a day with strict sub-100ms SLAs, so performance, scalability, and operational excellence will guide every project you take on
- You will independently translate ambiguous business problems into simple, robust technical designs, raise the engineering bar through code review and mentorship, and champion the application of the latest technologies, including AI, to solve hard AdTech problems
- This role will be based in our San Carlos local office. Our team follows a hybrid schedule, working in the office three days a week and remotely for the rest
- Serve as a senior engineer on a talented team building critical, high-performance, largescale services for Nexxen DSP programmatic integrations and platform products
- Independently transform vague business requirements into simple, well-reasoned
- Technical designs and drive them from concept through production
- Partner closely with the Product team, the Engineering Manager, and cross-functional teams
- Stakeholders to shape requirements, scope, and roadmap
- Take full ownership of complex initiatives, end-to-end design, implementation,
- Integration, rollout, and post-launch operation
- Write solid, testable, and performant code for services supporting high throughput and low latency (< 70ms response time)
- Set the technical bar through code reviews and pair programming, inspiring mid- and junior-level engineers to write simple, testable, and performant code by example
- Mentor and uplevel teammates; act as a force multiplier for the broader engineering organization
- Apply an SRE mindset to production deployments—observability, on-call readiness, incident response, capacity planning, and continuous reliability improvements
- Identify and resolve performance bottlenecks in large-scale distributed systems that process billions of transactions per day with strict SLAs
- Drive increased test, monitoring, and automation coverage across services, including automated acceptance testing
- Collaborate on technical design across teams and contribute to architectural decisions for the DSP platform
- Explore and prototype the application of emerging technologies, especially AI, to solve technical and AdTech problems
- Operate within Agile / DevOps practices in a fast-paced environment where you can quickly see the results of your work
- Lead and participate in planning, grooming, and architectural review sessions with the team and stakeholders
Our take
Video has been an invaluable marketing tool for businesses since the beginning of TV advertisement, but modern technology has dramatically changed how such content is consumed. On-demand omnichannel streaming services and CTV has provided unique opportunities for advertisers to develop their audience engagement strategies, but without the appropriate technology platform, this can be difficult to navigate.
Nexxen provides an end-to-end self-service CTV & video marketing platform, helping to provide businesses with the appropriate engagement tools to future-proof their video marketing. The platform includes AI-driven analytic tools based on audience data, marketplaces for the self-serving of media for campaigns, in addition to analytic tools to assess the success of campaigns in real-time.
Whilst several other start-ups provide either video engagement tools or self-serve video marketing marketplaces, Nexxen has taken the smart angle of combining both into a single platform, whilst specialising in futureproofing companies for the rise in CTV engagement demands. The company aims to save clients money, time, and operational complexity by unifying where they operate their video advertisement campaigns into a single platform.
