If you're excited by the grit of building, rapid learning, and shaping the future of customer growth, you'll find your place here.

About the role

The Performance Engineering team delivers customer-facing capabilities that directly improve marketer outcomes across three areas: Fraud (detection rules, model integration, clear explanations, and case-review workflows), Insights (in-product analytics, actionable recommendations, and experimentation surfaces across the MMP), and Partner Integrations (SAN/partner APIs, parity updates, webhooks/postbacks, and durable data contracts). 

This role is under our Fraud and Insights group to build and evolve Branch's Fraud & Performance product: real-time fraud defenses, post-facto adjudication, and marketer-facing insights that improve ROAS. You'll ship features across rules + ML scoring, explainability & evidence, case review workflows, A/B & incrementality hooks, and partner-safe parity so customers can trust counts and optimize spend.

What you'll do

• Ship fraud controls & performance features: detection rules, score aggregation, thresholds, appeals/adjudication flows, auto-actions (block/discount/quarantine), and "evidence packs."
• Own explainability & transparency: reason codes, decision timelines (winner/loser touches), feature attributions, and support-ready traces.
• Integrate models safely: wire DS-provided models (batch/online) with versioning, shadow tests, drift monitors, and rollback paths.
• Design contracts & validation: Protobuf/Avro schemas, backward/forward compatibility, policy checks at edges (no PII leaks; consent/ATT aware).
• Insights & experimentation: surface fraud/performance insights in-product; add guardrails for A/B, geo holdouts, and iROAS reads (incrementality).
• Partner hygiene: keep SAN/DSP parity for fraud signals and performance metrics; adapt to ICR/API changes without breaking customers.
• Quality & observability: author integration/contract tests, golden-path e2e checks; emit structured metrics/logs, dashboards, and alerts Support can use.
• Collaborate cross-functionally: work closely with PM, DS/ML, Design, Support/Partner Ops to prioritize impact and ship predictably.
  
  

What you bring

• 5+ years building customer-facing backend or full-stack products; strong Java/Kotlin.
• Experience in fraud/quality systems or high-trust analytics (rules engines, scoring services, appeals/case tools, reason codes).
• Solid testing discipline: unit, property, contract, and integration tests; feature flags and staged rollouts.
• Data chops: SQL, metrics design, cohort analysis; comfort reading DS model outputs and validating business impact.
• Clear, pragmatic communication; crisp design docs

Nice to have

• MMP/adtech exposure (attribution, SKAN/Privacy Sandbox, SAN partners).
• Experimentation (A/B, CUPED, Diff-in-Diff) and incrementality metrics (CPIe, iROAS).
• Risk/fraud patterns: CTIT, click spamming, SDK spoofing, device/IP density; drift detection.
