Staff Software Engineer

WHO WE ARE . The Role We'rehiring multiple Staff Engineers to join a small, high-performance group supporting the engineering organizations behindSailthru,LiveIntent, andWhatCounts— the three platforms that make up Zeta Actions, a business unit within Zeta Global. This is a deeply technical IC role.You'llspend most of your time in the code, the architecture, and the hard problems these teams run into as they build andoperateplatforms that serve brands and publishers at massive scale. Staff Engineers engage with teams in a fewdifferent ways— as a technical partner on complex projects, as a hands-on contributor to high-priority initiatives, or as an on-demand expert for teams that hit an architectural wall. The common thread is thatyou'resomeone teams want in the room when things get hard. Why This Role Real scale, real complexity — billions of messages, live traffic, meaningfulperformanceand reliability constraints. Generative AI is part of how we work —we'veadopted AI-assisted development across the engineering organization and expect our staff engineers to be fluent in these tools, not just aware of them. Active investment in AI engineering —you'llhelp shape how we build AI capabilities into the platform itself, not just use them in your own workflow. Real autonomy — youwon'tbehandeda backlog.You'llbe expected to find the important problems, make the case for solving them, and drive them to resolution. The best staff engineers here create their own leverage. Curiosity is a first-class traitonthis team. We value engineers who read widely, ask uncomfortable questions, andaren'tsatisfied with how things work until they understand why. What You'll Do Technical Leadership Identifysystemic engineering challenges across our platforms and drive their resolution — shaping the technical backlog and near-term architecture. Propose andvalidatetechnical approaches for problems involving scale, performance, security, or cross-team dependencies. Lead architectural decisions for complex, ambiguous, or high-risk initiatives. Incorporate modern industry patterns — including AI/ML tooling — into our technical strategy where it genuinely moves the needle. Hands-On Execution Write code, review PRs, debug production issues, and optimize system performance — this is not a whiteboard-only role. Dive deep into our AWS infrastructure, Kubernetes workloads, and JVM-based services to find and fixwhat'sactually wrong. Participate in our on-call rotation as a second-level escalation point for complex engineering incidents. Step in during large incidents to help teams triage, coordinate, and resolve — and follow through with post-incident reviews that drive lasting fixes. Champion operational excellence across our engineering teams: observability, reliability, deployment practices, and the operational habits that keep systems healthy at scale. Cross-Team Influence Partner with engineering teams as a technical point of contact on complex projects — ensuring good architectural decisions get documented anddon'thave to be re-litigated. Work directly with Engineering Managers to align technical work with team and product priorities. Mentor engineers across our teams, raising the technical floor through reviews, pairing, and direct feedback. Stay close to the customer. Understand howSailthru'splatform affects the people using it, bring that context into technical decisions, and push back when engineering choices create friction for customers. Partner closely with the product team — contribute to shaping what gets built, not just how. The best technical decisions happen when engineering and product are thinking together from the start. What You'll Bring Deep, battle-testedexpertisein AWS and cloud-native architecture — you know how to build reliable, scalable systems at real traffic volumes. Strong JVM fundamentals, primarily Java and Kotlin, with the range to work across languages as the problem demands. Hands-on Kubernetes experience — deploying,operating, and troubleshooting workloads in production. Experience designing andoperatingdistributed systems — fault tolerance,consistencytradeoffs, service coordination, and failure modes at scale. Comfort working with large databases at scale — query optimization, schema design, operational concerns, and the tradeoffs between data storage approaches. Practical experience with AI/ML engineering — whether integrating LLM capabilities, building pipelines, or evaluating where AIactually helpsvs. adds complexity. A track recordof delivering large, complex initiatives in ambiguous environments — scoping, driving alignment, and shipping. Strong debugging instincts and a bias toward root-cause analysis over symptomatic fixes. The judgmenttoknow when to push for the right solution and when pragmatism wins. Fluency with AI-driven development tools — Claude Code, GitHub Copilot, Codex, or similar — is a firm requirement. We use these tools daily and expect staff engineers to be effective with them and to model best practices around prompt discipline, output validation, and security. Comfortoperatingwithout a playbook —you'vesolved novel problems before and know how to navigate uncertainty. Comfort working in and around legacy codebases — you can read unfamiliar code, understand systems that predate you, and make meaningful improvements without needing a rewrite. The ability to quickly map an existing architecture —identifybottlenecks, constraints, and opportunities — and turn that understanding into concrete, actionable proposals that increase team velocity. You think big.You'renot constrained by how things are done today — you can envision meaningfully better outcomes and work backwards from them to find a path. Bias for action.You'drather move with imperfect information and course-correct than wait for certainty that never comes. You know the difference between a reversible decision and one thatwarrantsmore care. Experience with PHP or Python is a plus. Familiarity with high-volume messaging infrastructure or email/marketing tech is welcome but notrequired. Knowledge of the Databricks platform and data engineering practices (pipelines,lakehouses, batch and streaming processing) is a bonus. Working Here This role sits within Zeta Actions — the Zeta Global business unit encompassingSailthru,LiveIntent, andWhatCounts.We'reremote-first with engineers across the US. The scale of what these platforms do — high-volume delivery, real-time identity resolution, personalization at billions of touchpoints — means the problems are genuinely hard. Ifthat'swhat energizes you,we'dlike to hear from you.
