Mid Level Software Developer Jobs in Issaquah, WA

Job Summary:
QXO, Inc. is the largest publicly traded distributor of roofing and building materials in North America, aiming to become a tech-enabled leader in the industry. The Staff Software Engineer, Salesforce will bridge the gap between CRM excellence and modern cloud architecture, architecting end-to-end solutions that integrate Salesforce with Google Cloud Platform.
Responsibilities:
• Lead by example as a primary individual contributor, developing complex features that simultaneously harden our core Salesforce frameworks.
• Design and maintain high-performance, bi-directional integrations between Salesforce (and adjacent SaaS tooling) and GCP, utilizing Pub/Sub, Cloud Functions, or Dataflow to bypass traditional platform governor limits.
• Architect a seamless bridge between the front-end (LWC), the back-end (Apex), and the cloud (GCP). You will be the primary advocate for Service Sovereignty, designing patterns that ensure Salesforce, and GCP interact as a cohesive unit. Your goal is to build a high-performance, 'platform-agnostic' user experience that hides the complexity of cross-cloud API calls and event-driven data flows from the end user.
• Establish 'Shift Left' standards for the Salesforce team, including robust CI/CD pipelines, agentic development, automated testing, and containerized deployment patterns.
• Act as a force multiplier by upskilling mid-level Salesforce developers in full-stack best practices and guiding generalist engineers on Salesforce-specific architectural constraints.
• Evaluate when to leverage native Salesforce functionality versus when to offload heavy processing to GCP microservices to optimize for cost, performance, and scalability.
• Partner with InfoSec to ensure data integrity and encryption standards are maintained as sensitive information moves between Sales, Marketing and adjacent systems.
Qualifications:
Required:
• 8+ years of software engineering experience, with at least 4+ years specifically architecting and developing on the Salesforce platform at scale.
• Mastery of Apex and LWC: Deep expertise in writing modular, asynchronous, and bulk-safe Apex, along with advanced Lightning Web Component development (State Management, Lightning Message Service).
• Distributed Systems & Integration: Hands-on experience designing Event-Driven Architectures using tools like Salesforce Platform Events, Change Data Capture (CDC), and message brokers (e.g., Pub/Sub, Kafka, or RabbitMQ).
• Full-Stack Proficiency: Hands-on experience building applications in at least one backend language outside of Salesforce (e.g., Node.js, Go, Python, or Java).
• API Design: Expert-level understanding of RESTful API design, OAuth 2.0, and managing service boundaries between a CRM and external cloud services.
• Modern DevOps/DX: Experience with Salesforce DX (SFDX), version-control-based development (Git), and building automated CI/CD pipelines (GitHub Actions, GitLab CI, or similar).
• Technical Leadership: Experience acting as a Staff or Lead Engineer, mentoring mid-level developers and driving architectural decisions across multiple teams or workstreams.
Preferred:
• Framework Builder: A history of creating and open-sourcing (or internally evangelizing) reusable frameworks (e.g., Custom Trigger Frameworks, Unit Testing Mocking utilities, or LWC Base Component libraries).
• Certified Architect: Holds Salesforce Certified Technical Architect (CTA) or System/Application Architect credentials, or Google Professional Cloud Architect certification.
• GCP Cloud Native: Deep experience with Google Cloud Platform, specifically Cloud Functions, Cloud Run, Pub/Sub, BigQuery, and Workload Identity Federation.
• Data Engineering at Scale: Experience managing massive datasets that span Salesforce and external data lakes, including knowledge of Salesforce Connect, Big Objects, or OData.
• Security-First Mindset: Familiarity with Salesforce Shield, Event Monitoring, and implementing zero-trust security patterns across a multi-cloud stack.
• System Observability: Experience setting up distributed tracing and centralized logging (e.g., streaming Salesforce logs to GCP Cloud Logging or Splunk).
