Sponsors, but it's cap-subject — you still face the weighted lottery (~45% per draw at Level III). Good if you win; have a cap-exempt backup on your list.
Lottery odds assume a STEM candidate.

the lottery is wage-weighted — each level is one more entry
$16,398 more — $141,398 — moves this role to Level III and 3 lottery entries. That figure is inside the range the employer already advertised.
Based on the DOL prevailing wage for this occupation and worksite, a base salary of $141,398 would place this position at wage Level III. That figure is within the posted range, and I'd like to target it. This role classifies under "Software Developers" for prevailing-wage purposes.

Responsibilities
- You'll embed with internal teams, find the highest-leverage automation opportunities, and own them end-to-end: discovery, simplification, build, deployment, and adoption.
- Design and build multi-step agentic workflows in Python and TypeScript - planning loops, tool dispatch, error recovery, and explicit human-in-the-loop checkpoints for high-stakes decisions
- Develop production LLM applications on Anthropic and OpenAI SDKs, including prompt engineering, structured outputs, tool/function calling, prompt caching, and batch processing
- Own eval discipline end-to-end: define offline eval sets, run A/B experiments on model changes, build regression suites, and articulate "good enough" exit criteria using LangSmith, Braintrust, or equivalent
- Drive cost and latency optimization - token budgets, model tier selection (Haiku / Sonnet / Opus and GPT equivalents), and caching strategies that hold up at scale
- Build MCP servers and function-calling connectors that give agents reliable, schema-governed access to internal tools, APIs, and data sources - Jira, CRM, Slack, internal services, and more
- Implement and maintain production integrations using REST, GraphQL, webhooks, and event-driven patterns (queues, Pub/Sub) with proper idempotency, retry logic, and backfill support
- Own cloud infrastructure for AI workloads on GCP using Terraform, GKE/Cloud Run, and secrets management - with logging, metrics, and alerting from day one
- Build data pipelines that feed AI systems: strong SQL, Athena/BigQuery-class warehouses, ETL/ELT, schema design, and data-quality monitoring
- Partner with internal teams across Engineering, Operations, Customer Support, Data, and Finance to identify where agentic automation can have the highest leverage - then build it
Requirements
- Production LLM application experience with Anthropic or OpenAI SDKs - agents, structured outputs, tool use, RAG, evals, batch processing - shipped, not demoed
- Forward-deployed instinct: engineering, developer relations, or solutions engineering experience
- Strong evaluation discipline with the ability to define and defend exit criteria using LangSmith, Braintrust, or equivalent tools
- Strong understanding of token budgets, model tier trade-offs, and AI cost/latency optimization strategies
- Experience integrating REST APIs, GraphQL, webhooks, OAuth/SAML authentication (especially Okta), and event-driven architectures
- Cloud-native engineering experience with GCP or AWS, including Terraform, containers, secrets management, logging, metrics, and alerting
- Strong SQL and data engineering experience with modern warehouses, ETL/ELT pipelines, schema design, and data-quality monitoring
- Ability to work cross-functionally and translate ambiguous business problems into production-ready AI systems
- Experience with LangChain, LlamaIndex, or similar orchestration frameworks
- Familiarity with observability tooling such as OpenTelemetry, Prometheus, and Grafana
Nice to have
- 5+ years of production software engineering experience, primarily in Python or TypeScript.
