About The Position

The LOS Developer III is a senior technical contributor and/or lead who owns complex LOS architecture, major integrations, platform modernization, and reliability. This role drives technical strategy, mentors engineers, establishes best practices, and partners with leadership to align the LOS roadmap to business outcomes, compliance, and risk posture.

Requirements

• Strong understanding of security architecture (IAM, secrets, encryption, secure API design) and operational excellence.
• Architecture: API gateway patterns, messaging/queues, eventing, schema/version strategy
• Reliability: SLIs/SLOs, monitoring strategy, runbooks, capacity planning
• Security: OAuth/OIDC, certificates, secrets vaults, data encryption, access controls
• DevOps: mature CI/CD, automated tests, environment strategy, infrastructure collaboration
• Data: lineage/mapping, reconciliation, quality rules, governance controls
• Technical leadership and influence across teams
• Strong written communication (design docs, ADRs, postmortems)
• Risk management mindset (operational, security, compliance)
• 7+ years of experience in relevant engineering experience, including significant systems integration ownership.
• Demonstrated leadership in solution architecture and delivery for mission-critical financial systems.
• Expert-level SQL and strong proficiency in at least one primary language/stack; proven ability to design reliable integration services.

Nice To Haves

• Deep expertise in a major LOS platform and its customization/integration ecosystem.
• Experience with enterprise integration patterns (event-driven, queues, ESB/iPaaS, API gateways).
• Familiarity with mortgage-specific data standards (MISMO), reporting requirements, and audit/compliance controls.
• Experience leading migrations (on-prem → cloud, legacy services → modern APIs, monolith → modular).

Responsibilities

• Architect, design, and lead delivery for large-scale LOS initiatives (new LOS modules, major workflow redesigns, enterprise integrations, platform migrations).
• Define and enforce engineering standards: integration architecture, data quality rules, versioning, secure coding, logging/monitoring, and release governance.
• Own high-impact integrations (e.g., pricing/product, doc generation/eClose, AUS, identity, servicing boarding) and ensure resilience (retries, idempotency, back-pressure, failover).
• Lead technical discovery with business, compliance, and operations; produce solution architectures, estimates, and risk assessments.
• Establish and improve DevOps and SRE practices for LOS: CI/CD, automated testing, monitoring/alerting, incident response, and postmortems.
• Ensure compliance considerations are embedded (audit trails, data retention, access controls, least privilege, change management).
• Mentor and coach Developers I/II; lead reviews of designs and implementations; identify skill gaps and training plans.
• Partner with vendors and internal enterprise teams to manage interfaces, SLAs, and roadmap dependencies.
