Job description

Senior Backend Engineer – LA28 Olympic & Paralympic Games

This role focuses on designing and operating distributed systems that must perform reliably under extreme, bursty traffic conditions, such as global on-sale events with massive concurrency and adversarial bot activity. You will work on high-impact systems where performance, fairness, and reliability directly affect millions of users in real time.

Candidate level: Senior Engineer I or II based on experience and interview performance.

What You’ll Do

• Own the design, build, and operation of backend systems powering global ticketing, including LA28.
• Design distributed systems that handle unpredictable, high‑concurrency traffic (10x‑100x spikes during on‑sale events).
• Drive architectural decisions across services, balancing trade‑offs between scalability, latency, cost, and reliability.
• Build and evolve API‑driven services used by internal systems and external partners at scale.
• Analyze and optimize system performance using load testing, production telemetry, and observability tooling.
• Design for correctness under concurrency, including challenges like fairness, queuing, and race conditions.
• Develop and implement strategies to mitigate fraud, abuse, and bot traffic in high‑demands environments.
• Lead design and code reviews, influencing engineering standards and long‑term system architecture.
• Collaborate with product and business stakeholders to define solutions in ambiguous problem spaces.
• Leverage AI‑assisted development tools to accelerate iteration and improve code quality.

What You Bring

• Strong experience with C# and .NET / .NET Core, or a Java background with willingness to work primarily in C#.
• Proven experience building and operating distributed systems at scale in production environments.
• Deep understanding of concurrency, fault tolerance, and system design trade‑offs.
• Experience designing and scaling API‑driven services in cloud environments (AWS preferred).
• Strong experience with performance tuning, bottleneck analysis, and system reliability.
• Solid foundation in service‑oriented or microservices architectures.
• Experience with relational databases and data modeling at scale (SQL Server, PostgreSQL, MySQL, etc.).
• Familiarity with infrastructure‑as‑code and modern cloud‑native patterns.
• 4+ years of professional software development experience.
• Bachelor’s degree in Computer Science or equivalent experience.
• Experience mentoring engineers and influencing technical direction.
• Strong communication skills and a high sense of ownership.

Nice to Have

• Experience with event‑driven architectures or streaming systems (e.g., Kafka).
• Experience with NoSQL systems (e.g., DynamoDB, Elasticsearch) in high‑scale environments.
• Familiarity with containerization and infrastructure tooling (Docker, Terraform).
• Experience in ticketing, e‑commerce, or other high‑volume transactional domains.
• Familiarity with TDD/BDD and engineering best practices.

Pay Scale

$130,000 - $150,000

Benefits

Medical, dental and vision insurance, paid holidays, vacation and sick time, company‑paid basic life insurance, voluntary life insurance, parental leave, 401(k) plan (match 3%), flexible spending and health savings account options, and wellness offerings. Full‑time employees are eligible for these benefits on the first day of employment.

• Employer does not offer work visa sponsorship for this position.
