Principal Engineer (Platform Integration)

Principal Engineer (Platform Integration) Role SummaryThe Principal Software Engineer is the senior technical authority for the Platform Services layer, owning the reliability, resilience, and modernization of a mission-critical services portfolio recently migrated to Azure. This is a pure individual contributor role focused on deep technical leadership, architectural decision-making, and hands-on engineering across a broad set of shared platform services. You are the primary voice for platform stability, observability, and cloud-native evolution, partnering closely with the Engineering Manager and Scalable Architecture Team to guide modernization strategy.

Core Focus Areas •

Platform Reliability & Observability:

Strengthen production stability through improved observability, SLOs/SLIs, alerting, and resilient service patterns across multiple ecosystems. •

Architecture & Technical Ownership:

Own architectural direction and engineering standards for the services portfolio; identify high-impact improvements and sequence modernization efforts. •

Legacy Modernization:

Reduce technical debt and production risk while migrating legacy .NET services toward a cloud-native future, balancing short-term stability with long-term investment. •

Hands-On Engineering:

Write, review, and debug production code across services, databases, and cloud infrastructure. •

AI-First Engineering:

Set the standard for agentic development by deeply integrating AI tooling into daily work and driving measurable improvements in quality and velocity. •

Technical Leadership & Mentorship:

Raise the technical bar across the team through standards, best practices, and mentorship-without direct people management responsibilities.

Ideal Candidate ProfileA senior or principal-level engineer with 8+ years of enterprise SaaS experience, deep expertise in C#/.NET, Azure, Oracle, and service reliability engineering. Strong background in observability, resilience patterns, event-driven architectures, and legacy modernization, paired with an AI-first development mindset and the ability to influence platform direction through technical leadership rather than management authority•Official Job DescriptionJob DescriptionAs a Principal Software Engineer on the Platform Services team, you will serve as the senior technical authority for the services layer of the platform•a portfolio of services spanning data processing, file transfer, financial data feeds, communications, compliance, and shared infrastructure. Reporting to the Engineering Manager, you will own the reliability, observability, and modernization of these services across multiple production ecosystems.

This is a pure IC role. Your job is to write great code, make sound architectural decisions, and drive the technical evolution of a mission-critical platform that was recently migrated to Azure and is now entering a cloud-native modernization phase. You will be the go-to technical voice for platform reliability, resilience, and shared engineering standards on the Platform Services Team, partnering closely with the Scalable Architecture Team as they define the future-state design patterns this portfolio will adopt.

The services you own span a wide range of modernization stages•some recently refactored, others carrying significant technical debt. Your immediate mandate is improving the reliability and resilience of these services in their current state•reducing fragility, improving observability, and ensuring production stability across multiple ecosystems. The longer-term opportunity is to partner with the Scalable Architecture Team to determine the right cloud-native path forward and sequence the modernization of legacy services into that future state.

You will bring an AI-first mindset•genuinely integrating agentic development tooling into your daily workflow and setting the standard for your team.

ResponsibilitiesPlatform Reliability & ObservabilityOwn and evolve the platform's observability posture•structured logging, distributed tracing, health check endpoints, and correlation tracking•ensuring consistent adoption and coverage across all services.

Drive SLO/SLI definition and dashboard creation; expand alerting coverage from log-based alerts to include APM metrics, latency, and throughput.

Identify and eliminate reliability anti-patterns across the portfolio•replacing fragile legacy patterns with resilient, cloud-native alternatives.

Implement proper resilience patterns•circuit breakers, retry policies, graceful degradation, dead-letter handling, and idempotent message processing.

Replace legacy messaging anti-patterns (database polling, file-system coupling) with event-driven messaging infrastructure•this is the highest-impact reliability improvement available to the platform today.

Technical Ownership & ArchitectureServe as the senior technical authority for the Platform Services portfolio•owning architecture, reliability, and engineering quality across a broad set of production services.

Assess the current state of the service portfolio, identify the highest-impact reliability and modernization opportunities, and build a sequenced roadmap in partnership with the Scalable Architecture Team and Engineering Manager.

Evaluate and recommend the right cloud-native Azure services and patterns for the platform's future state•this is an open architectural question you will help answer, not a predetermined path.

Own shared library and cross-cutting infrastructure used across the service portfolio; ensure consistent adoption of engineering standards across all services.

Ensure production stability across multiple independent deployment ecosystems throughout the modernization process.
