Adtech Engineer Jobs in Chicago, IL (NOW HIRING)

For two decades, CORE ID has powered Epsilon’s own digital business at commercial scale through every major industry shift — the deprecation of third‑party cookies, the rise of connected TV, the ongoing fragmentation of the identity landscape. That durability is proof that this is not a research project or a vendor claim. It is the identity spine Epsilon has trusted for its own revenue.

The Connected Access Team changes that by opening Epsilon’s identity spine to clients in new ways for the first time — delivering CORE ID directly into the environments where their data already lives: CDPs, clean rooms, and cloud data platforms.

• Shape and execute the Connected Access roadmap for your capability area — from CORE ID partner environment integrations to Delta Sharing and Federated Query patterns to the Connected Identity Service — with clear ownership from discovery through delivery.
• Lead enterprise client engagements — run discovery, translate client data requirements and privacy restrictions into precise product specs, and build the trust with key accounts that turns a Phase 1 pilot into a scaled, multi‑year relationship.
• Define requirements at the intersection of business and technical complexity — identity mapping outputs, composable data sharing flows, clean room integration patterns, and the jurisdictional nuances (California Drop support, data residency) that determine whether a client can actually use the product.
• Collaborate with Business Development and Alliance teams — progress partnership agreements involving Databricks, Adobe, Amazon, Salesforce, and Cordial. Translate commercial outcomes into product integration timelines and the other way around.
• Own the metrics story for your capability area — track and communicate progress against Connected Access’s success targets to leadership and cross‑functional stakeholders.
• Navigate a multi‑team dependency landscape — Connected Access does not build the core identity infrastructure; it surfaces, composes, and deploys it. You’ll maintain delivery momentum across data platform, engineering, legal, and partner teams without owning every upstream build.
• Contribute to go‑to‑market readiness — help define the client onboarding model, inform the revenue structure (identity activation fees, platform access fees, partner distribution revenue), and establish what a successful Phase 1 launch actually looks like in practice.

• Solid grounding in name‑based and digital identity resolution, CDPs, data clean rooms, or cloud data platforms — enough to earn credibility with enterprise clients and technical partners on day one.
• Familiarity with composable data sharing patterns — Delta Sharing, Federated Query, zero‑copy architectures, or similar. You won’t build the infrastructure, but you need to understand it well enough to prioritize, negotiate, and make tradeoffs.
• Experience in B2B or enterprise SaaS, balancing customer‑focused requirements, partner‑influenced roadmaps, and internal strategic priorities.
• Comfort in the adtech or martech landscape — understanding where identity sits in the broader ecosystem and what it actually unlocks for a marketer trying to activate across channels.

• Technically comfortable: able to engage credibly with engineering on integration patterns, hold your own in partner conversations with Databricks or Adobe technical teams, and follow a data residency discussion without losing the thread.
• Strong client instincts — able to surface the real requirement beneath what a client is asking for, and translate it into product decisions that hold up under engineering and legal scrutiny.
• Experience managing enterprise relationships where the product is complex, the stakes are real, and trust is built slowly and lost quickly.

• Comfortable operating in ambiguity — Connected Access is a new product in a space that is still defining itself. You’ll make calls with incomplete information and be willing to revisit them as the picture clarifies.
• Sharp written and verbal communication: able to synthesize a complex capability area for a leadership audience, walk a client’s legal team through a privacy‑safe data output pattern, and give engineering a clear target — sometimes in the same day.
• Rigorous prioritization instincts when cross‑team dependencies are real, partner agreement timelines are uncertain, and delivery windows are tight.

• Proven ability to lead through influence — Connected Access depends on teams it doesn’t control. Building alignment across product, engineering, BD, legal, and partner organizations without positional authority is the job.
• Coachable, direct, and invested in getting it right — willing to push back clearly when something isn’t working, and equally willing to update your view when new evidence changes the picture.
• Track record in cross‑functional environments where product is the connective tissue between commercial commitments and engineering delivery.

• Direct experience with identity resolution platforms or data clean room technology (e.g., Habu, LiveRamp Safe Haven, Amazon Clean Rooms, Databricks Clean Rooms, and Snowflake Clean Rooms).
• Hands‑on familiarity with cloud data platform ecosystems — Databricks, Snowflake, AWS, or similar — particularly around data sharing, marketplace integrations, or federated access patterns.
• Background at an adtech, martech, or data infrastructure company where identity was core to the product, not adjacent to it.
• Experience building or scaling a net‑new product within an established enterprise organization.
• 7+ years of product management experience, with at least 2 years owning an enterprise or B2B product roadmap.

• Time to Recharge: Flexible time off (FTO), 15 paid holidays
• Time to Recover: Paid sick time
• Family Well‑Being: Parental/new child leave, childcare & elder care assistance, adoption assistance
• Extra Perks: Comprehensive health coverage, 401(k), tuition assistance, commuter benefits, professional development, employee recognition, charitable donation matching, health coaching and counseling
