Software Engineer – IAM Full Time NEW

About us: At Booking.com, data drives our decisions. Technology is at our core. And innovation is everywhere. But our company is more than datasets, lines of code or A/B tests. We’re the thrill of the first night in a new place. The excitement of the next morning. The friends you encounter. The journeys you take. The sights you see. And the memories you make. Through our products, partners and people, we make it easier for everyone to experience the world

About the team: Booking.com (USA), Inc, one of the support companies in the United States, is seeking a full time Software Engineer in Washington, DC for the IAM team within the Data and Machine Learning department. The IAM team builds and operates the identity and access management layer for Booking’s central data platform, enabling secure and compliant access to data. The team owns access provisioning, enforcement, and credential management. We focus on ensuring the right people and services have the right access at the right time, with strong guarantees around auditability, compliance, and reliability, while keeping access workflows efficient and scalable.

Role Description: This role focuses on building and operating the identity and access management (IAM) platform for Booking’s data ecosystem across Snowflake and AWS S3. You will design and maintain the systems that control how humans and services access data, ensuring strong guarantees around security, compliance, and auditability, while minimizing friction for users. You will own the full access lifecycle – from identity and role provisioning, to access request flows, to enforcement and audit – integrating across systems. This role sits at the intersection of data platforms, security, and compliance, and is critical to enabling scalable and governed data access across the company.

Key Job Responsibilities and Duties:

• Own the IAM Platform: Design, build, and operate the IAM layer that governs access to BDX data across Snowflake and AWS S3, using Immuta and internal services.
• End-to-End Access Lifecycle: Implement and maintain the full access lifecycle: identity onboarding, role provisioning, access requests, enforcement, and revocation.
• Policy Enforcement (Fine-Grained Controls): Enforce ABAC/PBAC policies, masking, row-level filters, and S3 Access Grants to ensure sensitive data is only accessed through approved paths.
• Compliance, Audit, and SOX Controls: Build and maintain auditability, access logging, and enforceable controls required for SOX and internal governance standards.
• Reliability, Observability, and Performance: Improve system reliability and reduce access provisioning latency through better observability, retries, and failure handling.

Important aspects of the job include:

• Operate in a highly integrated ecosystem (Snowflake, AWS, identity providers) and own the seams between systems.
• Take full ownership of access correctness – incorrect access is a security issue, not just a bug.
• Build for auditability by design, not as an afterthought.
• Continuously reduce friction in access workflows without weakening governance guarantees.

Role Qualifications and Requirements:

• Engineering Foundation: 3+ years building backend or platform systems in Java, Python, or similar.
• Distributed Systems & Reliability: Experience designing systems that are observable, fault-tolerant, and operate reliably at scale.
• Cloud Platform Experience: Hands-on experience with AWS (IAM, S3) and/or Snowflake or similar data platforms.
• Systems Integration: Experience integrating multiple systems (identity providers, data platforms, SaaS tools) into cohesive workflows.
• IAM & Security Fundamentals: Understanding of RBAC/ABAC, IAM roles and policies, authentication/authorization flows, and credential lifecycle management.
• Operational Ownership: Comfortable owning production systems, handling incidents, and improving system performance and reliability over time.
• Developer Experience Mindset: Ability to design platforms that are secure by default but easy to use and adopt.
