Top Tech Jobs & Startup Jobs in Seattle, WA

Build, optimize, and scale production Generative AI applications. Design multi-agent systems and LangGraph workflows, implement advanced RAG with LlamaIndex and vector DBs, fine-tune and deploy LLMs, and create high-performance FastAPI async backends. Improve latency, cost, and reliability, containerize services with Docker, and manage monitoring, API security, and CI/CD for ML deployments.

Design and implement data federation and lakehouse architectures, build scalable ETL/ELT pipelines with Python and Spark, optimize performance across federated queries, manage Delta/Iceberg/Hudi tables, and enforce governance, security, and access controls for analytics and AI teams.

Design, develop, and maintain scalable full-stack applications for intermediary clearing and custody platforms. Collaborate with product, architecture, and engineering teams to modernize applications, implement cloud migrations, build APIs, automate workflows, and improve CI/CD, observability, security, and deployment practices in an Agile environment.

Design, implement, and manage large-scale GCP infrastructure using IaC (Terraform), containerization (Kubernetes/Docker), monitoring, security, and DR. Mentor junior engineers, optimize performance and costs, and document practices.

Perform hands-on data governance: identify root causes using information management tools and data sources, collaborate with data owners and architects, define governance rules and values, embed governance tests into ETL, engage vendors and stakeholders, and establish/report on data governance metrics and continuous improvements.

Design and build Java-based, messaging and microservice applications. Lead API design, cloud/container solutions (Docker, Kubernetes, AWS/Azure), CI/CD, and relational database development (DB2/Oracle). Provide technical leadership, mentoring, code reviews, and resolve cross-technology roadblocks. Work on blockchain and digital asset solutions (Ethereum, Solana) and smart contracts (Solidity, Rust, Move) within financial services.

Lead cross-functional programs from planning through delivery, manage budgets and stakeholders, ensure quality and customer satisfaction, maintain program status reporting, and follow SDLC and project management best practices.

Lead requirements discovery and translate business needs into detailed user stories, functional specs, and acceptance criteria for e-commerce, loyalty, identity, and API-driven integration programs. Partner with product, engineering, QA, and architects to define API contracts, event-driven workflows, non-functional requirements, Gherkin test scenarios, and ensure traceability through delivery and release readiness.

Lead development of a unified payments platform covering pay-ins, payouts, merchant acquiring, settlement, routing, and reconciliation. Produce PRDs/BRDs, user stories, process maps, and API specs. Partner with engineering, QA, UI/UX, and data teams for agile delivery, release readiness, and operationalization. Define multi-rail routing, payment orchestration, and integrate billing, risk, and compliance.

Design and build RAG-focused data pipelines for LLMs: ETL/ELT for structured and unstructured data, vector database architecture, embedding and chunking strategies, data cleaning/PII removal, metadata engineering, low-latency streaming, and evaluation/versioning to support autonomous agents.
