Description

About the Role:

IAA is seeking a highly experienced Staff Engineer to join the IAA International team.

You will work within a collaborative, cross-functional engineering team, taking ownership of features and services across our microservices architecture, from design through deployment and operation. You will collaborate closely with Principal Engineers, Engineering managers, Architects, and cross-functional partners to design, build, and scale high-impact systems. We're looking for experienced engineers who are curious, pragmatic, and comfortable navigating a large, evolving codebase — and who embrace modern AI-assisted development practices to move faster and smarter.

Key Responsibilities:

  • Lead application modernization initiatives, including migration from legacy .NET Framework to modern .NET (.NET Core / latest LTS).
  • Drive architectural design for scalable, modular services and APIs supporting high-volume operational workflows.
  • Partner with Product and Architecture to decompose monolithic applications into well-defined domains and services.
  • Define and implement modern data‑access patterns using ORMs, repository patterns, and controlled schema migrations.
  • Improve system performance, resilience, and fault tolerance through sound design practices (timeouts, retries, idempotency, and graceful degradation).
  • Establish and enforce engineering standards for code quality, testing, and maintainability.
  • Embed observability into applications using structured logging, metrics, and distributed tracing (OpenTelemetry).
  • Design secure‑by‑default application patterns including authentication, authorization, secrets management, and secure coding practices.
  • Lead technical discovery and solution design for complex, cross‑team initiatives.
  • Mentor senior and mid‑level engineers through design reviews, code reviews, and hands‑on technical guidance.
  • Support and coordinate “level 3” incidents including after hours as necessary.
  • Collaborate closely with Infrastructure, Security, Data, and Operations teams to ensure solutions meet operational and compliance requirements.

Qualifications:

  • 8+ years of professional software engineering experience, with significant time spent modernizing large‑scale applications.
  • Demonstrated experience operating at a Staff or Principal Engineer level, influencing architecture and technical direction.
  • Deep expertise in C#, .NET, .NET Core, and modern application development practices.
  • Strong experience designing RESTful APIs and service‑oriented or domain‑driven architectures.
  • Hands‑on experience modernizing legacy systems and databases in production environments.
  • Strong understanding of relational databases and modern data‑access strategies.
  • Experience with cloud platforms (Azure preferred) and cloud‑native application patterns.
  • Excellent communication skills with the ability to clearly explain technical tradeoffs to engineering and business stakeholders.
  • Proven ability to lead through influence, mentor engineers, and raise overall engineering quality.

Bonus Experience:

  • Experience with high‑throughput, transaction‑heavy operational systems.
  • Exposure to event‑driven or asynchronous architectures.
  • Experience modernizing applications in regulated or compliance‑sensitive environments.
  • Familiarity with front‑end modernization (e.g., React) as part of full‑stack initiatives.
