Senior Machine Learning Data Scientist

Product Manager

• You run intake from across the company, prioritize against business value and technical readiness, and keep the queue of business-system connectors moving.
• You lead exec-prioritized cross-functional projects from intake through ship.
• You triage requests, manage office hours, and run the AI Builds and champion support channels.
• You hold the map of who owns what across DevX, DevOps, Product Engineering, and the network of Champions in the business.
• You run the planning, check-in, and reflect cadences.

• Design and ship secure MCP (Model Context Protocol) connectors to Extend's internal systems and the third-party SaaS we run on: finance, CRM, data warehouse, expense management, product analytics, support, ATS, and the long tail beyond.
• Build and curate the shared library of agent skills that every team at Extend composes from. Ship skills, codify patterns, and raise the floor for what a safe, high-quality skill looks like.
• Extend our agent infrastructure. Build the tooling that lets non-engineers create reusable agent skills securely and reliably. Encode the review and publishing model for shared tooling, shared runtimes, and the feedback loop on agent behavior in production. Fill the open phases of the lifecycle that governs how skills are designed, reviewed, and shipped, so non-engineers can build and ship intelligent automation end to end.
• Build toward a connector-building agent: a meta-agent that discovers APIs, scaffolds MCP servers, and provisions access automatically. The end state is a platform that is itself an agent.
• Work with our platform teams to establish the credential scoping, OpenTelemetry instrumentation, and least-privilege patterns that every connector and skill ships with, so security is built in from day one.
• Own the employee experience for the agentic platform. Help onboard employees to the tools with self-serve guides, build skills people can learn from, and run the feedback loop between what's shipped and what adopters actually need. Your job isn't done when the connector ships. It's done when the team using it is self-sufficient.
• Design credential scoping and vending for agent connectors: how API keys are provisioned, rotated, and scoped per user, per skill, per connector. OAuth/OIDC where it fits, least-privilege everywhere.
• Build the risk-tier and review model for shared agent skills: what's safe at personal, team, and org level; sandboxing strategy; malicious dependency scanning for skills that pull in untrusted packages.
• Instrument the agent platform end-to-end with OpenTelemetry: every MCP call, every skill execution, every credential use is visible in Coralogix.

Senior AI Software Engineer, Internal Enablement

Data Engineer

• You own our data warehouse and the reporting layer on top of it, setting patterns for how data is modeled, evolved, and exposed.
• You write SQL and dbt models, refactor transformations, and build the tables and views downstream teams rely on.
• You proactively engage with teams across the company to understand how data is created and used, identify gaps, and guide solutions.
• You partner with our DevX and architecture teams on the boundary between product engineering services and Snowflake.
• You build models, tests, and processes that anticipate malformed data and upstream changes, making our pipelines boring to operate.
• You instrument what you own, define meaningful SLOs and data quality checks, and participate in our rotating on-call schedule.
• You own and extend our Python jobs running on Glue, Lambda, and Step Functions.
• You pair with more junior engineers on real work, raise the bar on PR and architecture reviews, and define the patterns and standards the team writes against.

Manager, Machine Learning

Operations

• Real-Time Claim Review: Review claims in real time for potential cases of fraud/abuse, leveraging your information gathering and communication skills to ensure you have sufficient evidence to make a decision, and providing valuable feedback for Extend’s risk models.
• Risk Score Judgments: Review customer behavior and incidents using internal and external data and independently make decisions on customer risk. During the ramp-up period, you will only make judgments on risk scores; however, afterwards, you will also have the power to recommend denials and approvals for claims.
• Fraud Investigations and Subject Matter Expertise: Bring your own experience to perform fraud investigations and deliver insights on emerging trends for fraud/abuse.
• Follow Procedure: Take ownership of each investigation and diligently follow all regulatory and departmental practices and procedures, making independent decisions based on facts and evidence, and reporting any non-standard escalations to your manager. Attend regular meetings and training for Fraud Operations best practices.
• Cross-functional Work: Collaborate with Claims, Product, and Engineering, completing ad hoc tasks to evaluate and improve in-house models to detect fraud.
• Be Proactive and Adaptable: Drive team success and achieve both independent and collaborative goals, proactively completing additional tasks for the role as needed.
