Job Description

At Branch, we're transforming how brands and users interact across digital platforms. Our mobile marketing and deep linking solutions are trusted to deliver seamless experiences that increase ROI, decrease wasted spend, and eliminate siloed attribution. Our Branch team consists of smart, humble, and collaborative people who value ownership over all. Everything we do is centered around creating a great product, team, and company that lives and breathes our motto: Build Together, Grow Together, Win Together.
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.
