About the job

Lead Data Engineer - Onboarding and Identity

Commerce Media

Reporting to the Chief Product Officer

■ About the role

Navigator is building one of the fastest-growing commerce media networks in the market, a managed service and self-service business spanning US, EMEA, and APAC with an ambition to scale toward $300M in revenue. Data and identity infrastructure sit at the core of that growth: every advertiser and retail partner we bring onto the network depends on clean, well-structured audience data flowing seamlessly from ingestion through to activation, whether we’re running the campaign ourselves or enabling a client to activate independently.

We’re looking for a Senior Identity & Data Onboarding Engineer to own that pipeline end-to-end, from the moment a data partner’s hashed audience lands with us, through clean room structuring, to identity resolution and DSP-ready activation. This is a hands-on, build-and-own role for someone who wants to shape the data backbone of a network operating at serious scale.

■ What you’ll do

• Partner directly with data providers to define ingestion requirements for hashed email and other identifier feeds into our clean room environment
• Design and maintain the schemas, storage structures, and ordering logic that keep partner audiences clean, queryable, and correctly structured inside the clean room
• Work hands-on with identity partners (e.g. LiveRamp) to build and maintain the identity spine, resolving hashed identifiers into activation-ready IDs
• Structure and deliver audiences for activation across both our managed service campaigns and self-service client setups, including standing up PMPs and pushing deal IDs directly to a client’s own DSP seat
• Ensure resolved audiences are correctly packaged for our DSP stack (DV360, StackAdapt, Index Exchange, and others), regardless of who’s running the trade
• Troubleshoot match-rate, data quality, and latency issues across the ingestion-to-activation chain, working closely with both data partners and internal stakeholders
• Build repeatable, documented onboarding processes so new data partners and clients can be brought in quickly and reliably as the network scales
• Stay ahead of the evolving identity landscape (RampID, UID2.0, PAIR, and similar) and recommend where Navigator’s approach should evolve

■ What you’ll bring

• 5 to 8 years in data engineering, identity resolution, or data onboarding roles within adtech, martech, or commerce media
• Hands-on experience with data clean room environments (LiveRamp Clean Room, or equivalent), including schema design, data connections, and query/analysis rules
• Working knowledge of identity resolution concepts and infrastructure: hashed identifiers, deterministic/probabilistic matching, identity graphs, and pseudonymous ID spines
• Practical experience setting up PMP deals and deal ID delivery for DSP activation
• Direct experience working with identity vendors such as LiveRamp; familiarity with Experian, ID5, or similar identity/data providers is a plus
• Comfort working across DSP ecosystems (DV360, StackAdapt, Index Exchange, or similar) and understanding how activation requirements shape upstream data structure
• Strong SQL and pipeline/ETL skills, with comfort in cloud data environments (BigQuery, Snowflake, or similar)
• A partner-facing mindset. This role sits between external data providers, clients, and internal teams, so clear communication matters as much as technical depth

■ Why Navigator

You’ll be building core infrastructure for a network with genuine scale ambitions, working across global markets, with direct exposure to the identity and data partners shaping where the industry goes next.
