Senior Software Engineer - Network Enablement; Applied ML

Position: Senior Software Engineer - Network Enablement (Applied ML)
# Senior Software Engineer - Network Enablement (Applied ML)
Engineering San Francisco Full-time

We believe that the way people interact with their finances will drastically improve in the next few years. We’re dedicated to empowering this transformation by building the tools and experiences that thousands of developers use to create their own products. Plaid powers the tools millions of people rely on to live a healthier financial life. We work with thousands of companies like Venmo, SoFi, several of the Fortune 500, and many of the largest banks to make it easy for people to connect their financial accounts to the apps and services they want to use.

Plaid’s network covers 12,000 financial institutions across the US, Canada, UK and Europe. Founded in 2013, the company is headquartered in San Francisco with offices in New York, Washington D.C., London and Amsterdam.

The Network Enablement team’s mission is to amplify Plaid’s network effects by fostering trust and sharing intelligence with data partners.

We build Trust & Fraud Insights (real-time Protect model scoring, two-way APIs/webhooks, and investigation tooling), Bank Intelligence (ML driven retention and account-primacy metrics and scalable batch pipelines), and the ml/data foundations (graph and sequence-embedding models plus unified feature pipelines and feature-store patterns).We own productionization and reliability for data partner facing ML — low-latency scoring, offlineonline parity, observability and drift detection, PII-safe handling and auditability — and collaborated closely with MLE, DS, Data Platform, Fraud, Foundational Modeling, Product, and Privacy to scale network intelligence.

On this team you will build and operate the ML infrastructure and product services that enable trust and intelligence across Plaid’s network. You’ll own feature engineering, offline training and batch scoring, online feature serving, and real-time inference so model outputs directly power partner-facing fraud & trust products and bank intelligence features. You will integrate inference into product logic (APIs, feature flags, backend flows), build reproducible pipelines and model CI/CD, and ensure observability, reproducibility, and compliance as you scale our network capabilities.

You’ll partner with Product, ML/Data Platform, Fraud, Foundational Modeling, MLE, DS, and Privacy to ship auditable, reliable ML solutions that move product KPIs## Responsibilities
* Embed model inference into Network Enablement product flows and decision logic (APIs, feature flags, backend flows).
* Define and instrument product + ML success metrics (fraud reduction, retention lift, false positives, downstream impact).
* Design and run experiments and rollout plans (backtesting, shadow scoring, A/B tests, feature-flagged releases) to validate product hypotheses.
* Build and operate offline training pipelines and production batch scoring for bank intelligence products.
* Ship and maintain online feature serving and low-latency model inference endpoints for real-time partner/bank scoring.
* Implement model CI/CD, model/version registry, and safe rollout/rollback strategies.
* Monitor model/data health: drift/regression detection, model-quality dashboards, alerts, and SLOs targeted to partner product needs.
* Ensure offline and online parity, data lineage, and automated validation / data contracts to reduce regressions.
* Optimize inference performance and cost for real-time scoring (batching, caching, runtime selection).Ensure fairness, explainability and PII-aware handling for partner-facing ML features; maintain auditability for compliance.
* Partner with platform and cross-functional teams to scale the ML/data foundation (graph features, sequence embeddings, unified pipelines).
* Mentor engineers and document team standards for ML productization and operations.## Qualifications
* ** Must-haves:
*** Strong software engineering skills including systems design, APIs, and building reliable backend services (Go or Python preferred).
* Production experience with batch and streaming data pipelines and orchestration tools such as Airflow or Spark.
* Experience building or operating…
