About the Role

We are seeking a Senior MarTech Integration Engineer to own our event stream from Segment through all downstream destinations, including Braze, Amplitude, Snowflake, AppsFlyer, and ad platforms. You will be the technical owner of event data governance, transformation, routing, and consumption, ensuring schemas, identity, audiences, and delivery reliability. This role involves partnering with engineering teams to define event contracts and review instrumentation, driving toward a single, governed source of truth to support high-velocity growth experimentation.

Responsibilities

Own the event pipeline from Segment through all downstream MarTech destinations — Braze, Amplitude, Snowflake, AppsFlyer, and ad platforms.
Own destination configuration, transformations, audience sync, and delivery reliability.
Contribute to the evolution toward Segment as the single source of truth, including facade/proxy service patterns that decouple product code from destination-specific logic.
Define event contracts and schema standards, review instrumentation changes, and validate that payloads emitted by web, mobile, and backend systems are correct and complete before they enter the pipeline.
Own the identity model within Segment and downstream destinations — ensuring users are consistently and correctly resolved across event sources.
Implement and maintain Braze integrations, including audience sync, catalog/data feeds, and event-triggered messaging.
Validate Braze triggers, rendering, and data flows.
Partner with lifecycle marketing to translate campaign requirements into reliable implementations.
Own AppsFlyer configuration and mobile attribution.
Own UTM and web attribution integrity.
Own the downstream routing that lets us measure which channels drive acquisition.
Establish event schema standards, naming conventions, and QA gates.
Audit and manage destination configuration, event volume, and platform spend across the stack.

Requirements

5+ years of software engineering experience, with a focus on integrating third-party platforms and SDKs within complex ecosystems.
Strong SQL — able to independently validate data end to end, from raw event streams to warehouse tables.
Deep, hands-on experience with at least 2–3 of: Segment (or another CDP such as mParticle), Braze (or Iterable/Klaviyo/SFMC), Amplitude, Snowflake, AppsFlyer (or another MMP).
Direct experience with competitor tools in each category counts.
Working knowledge of web and/or mobile client technologies (React/NextJS, Swift, or Kotlin) — enough to review instrumentation, understand SDK behavior within application lifecycles, and partner credibly with product engineers.
Expertise in event-driven architecture, data instrumentation, and payload validation.
Proven track record troubleshooting distributed systems and ensuring data integrity across multiple platforms.
Exceptional communication skills — able to translate marketing and growth requirements into technical specifications, influence engineering teams you don't manage, and push back with data when requirements conflict with sound architecture.
