Web application developer Jobs in Seattle, WA

The AWS Field Experience (AFX) team builds go-to-market tooling that gives the AWS sales and marketing organization superpowers, helping them focus on customers instead of manual processes. As a Salesforce Developer, System Development Engineer II on AFX, you will design and deliver the Salesforce-based systems that power contracting, approval workflows, and deal management for the AWS field. You will build on the Salesforce platform (Apex, Lightning Web Components (LWC), Flows, and platform APIs) and integrate it with distributed services and LLM-powered automation that operate at AWS scale.

Salesforce is at the center of how AWS moves deals from opportunity to signed, executed contract, and large language models are redefining how we support that work. This is your chance to help shape that transformation. You will work across the full software development lifecycle, writing high-quality Apex and LWC code, contributing to system and data-model design, and collaborating with partners across the AWS partner business, deal desk, legal, finance, and solutions architecture teams.

Key job responsibilities
- Design and build Salesforce applications and APIs (Apex, Lightning Web Components (LWC), Flows, and platform integrations) that power contracting, approval workflows, and deal management for one of the largest field sales organizations in the world, covering the full lifecycle from design through deployment and operations.
- Develop and optimize approval-flow and workflow-orchestration logic on the Salesforce platform, including multi-stage routing, delegation, escalation, and gate enforcement, that keeps contracting fast, compliant, and fully auditable.
- Build and maintain integrations between Salesforce and external systems, synchronizing deal and account data across systems at scale and improving data quality and coverage.
- Implement LLM-powered workflows and automation that reduce manual effort for the sales field and generate actionable insights from complex contracting and account data.
- Participate actively in code reviews, providing constructive feedback that raises engineering standards, and mentor other engineers through documentation, training, and pairing sessions.
- Identify root causes of operational issues and drive permanent fixes, while collaborating with stakeholders across deal desk, legal, finance, the AWS partner business, and solutions architects to ensure your solutions meet real customer needs.


A day in the life
You start by reviewing pull requests from teammates (Apex classes and LWC components), offering detailed feedback that helps everyone grow. Mid-morning, you dig into a feature in the approval-flow logic, writing Apex and pairing with a colleague to work through a tricky integration between Salesforce and a downstream AWS services. After lunch, you join a design discussion with solutions architects about how an LLM-powered workflow can reduce manual steps for the field team. Later, you investigate an operational alert on a contracting flow, trace it to its root cause, and ship a lasting fix. You move between focused coding and cross-team collaboration with partners in deal desk, legal, and the partner business.
