Job Description

The Senior Software Developer is responsible to design, test, validate and support custom applications and databases focusing on complex business Requirements: and developing reports and dashboards.

Role Overview

We are seeking a high-caliber Senior Salesforce Developer to lead the technical implementation of our next-generation integration strategy. You will be responsible for transitioning our legacy CRM processes into a modern, near-real-time ecosystem that bridges Salesforce with our custom .NET/SQL Order Management System (OMS) using a high-scale Kafka backbone.

You will focus on data virtualization for Sites and Assets, ensuring our sales team has a mobile-ready, authoritative view of field operations directly within Salesforce.

Key Responsibilities:

• Architectural Implementation: Build and maintain the gRPC Pub/Sub handshake between Salesforce and our AWS-hosted Kafka Enrichers.

• Event-Driven Development: Develop and optimize Platform Events and Change Data Capture (CDC) triggers to stream construction project data to Confluent Kafka.

• Data Integrity & Resilience: Implement advanced error-handling patterns, including ReplayId tracking via DynamoDB and Idempotency checks via Redis, to ensure zero data loss during system downtime.

• High-Volume Integration: Build a resilient Kafka-to-Salesforce consumer using Bulk API v2 to update thousands of "Site" and "Asset" records while strictly adhering to Salesforce governor limits.

• UI/UX Customization: Design and develop Lightning Web Components (LWC) optimized for mobile form factors to display complex site asset hierarchies.

• Security & Identity: Manage and troubleshoot Azure AD SSO configurations and OAuth 2.0 JWT Bearer flows for secure service-to-service communication.

Technical Requirements:

• Salesforce Expertise: Minimum 5+ years of experience with Apex (Bulkification), LWC, and Flow.

• Integration Specialist: Proven experience with Pub/Sub API (gRPC), REST/Bulk APIs, and Apache Avro encoding.

• Architecture Knowledge: Familiarity with AWS services (ECS, DynamoDB, ElastiCache/Redis) and Confluent Kafka.

• Resilience Patterns: Deep understanding of Replay IDs, Dead Letter Queues (DLQ), and Circuit Breaker patterns in integration.

• Identity Management: Practical experience setting up SAML SSO with Azure AD (Entra ID) and Federation ID mapping.

Preferred Qualifications:

• Experience in the waste management or construction industry.

• Salesforce Platform Developer II or Integration Architecture Designer certification.

• Familiarity with .NET/SQL database structures for data mapping.
