Senior Fullstack Engineer (Java Heavy)

Secure Every Identity, from AI to Human

Identity is the key to unlocking the potential of AI. Okta secures AI by building the trusted, neutral infrastructure that enables organizations to safely embrace this new era. This work requires a relentless drive to solve complex challenges with real-world stakes. We are looking for builders and owners who operate with speed and urgency and execute with excellence.

This is an opportunity to do career-defining work. We're all in on this mission. If you are too, let's talk.

Position Description

We are seeking an experienced Senior Software Engineer to join the Advanced Integration Builder team within Okta. This team builds and maintains the backend services, provisioning frameworks, authentication connectors, and next-generation Entitlement Management engines that let Okta customers secure, integrate, and govern access to thousands of third-party enterprise applications — from modern cloud platforms (Microsoft Office 365, Workday, Salesforce, AWS, ServiceNow) and AI agentic systems to legacy on-prem systems. As a Senior Engineer, you will own the technical design and implementation of integration components end-to-end: REST/SOAP API clients, OAuth2/SAML authentication flows, user and group provisioning/sync jobs, and the retry and rate-limiting logic required to operate reliably against dozens of idiosyncratic third-party vendor APIs at scale. This is a backend-intensive role — the large majority of your time will be spent in Java/Spring Boot services — but you'll also need decent frontend experience in React and JSP to build and extend the screens that surface integration configuration to customers

Job Duties and Responsibilities

Feature Execution

Drive technical design and implementation of integration features — new app connectors, provisioning/sync capabilities, authentication flows — primarily in backend Java services, extending into React/JSP configuration screens.

• Build and maintain REST/SOAP API clients, OAuth2/SAML authentication handlers , and vendor-specific exception/error-mapping layers for third-party SaaS and enterprise applications.
• Implement and extend user/group provisioning adapters built on shared contracts and scheduled sync/import jobs that keep identity data consistent between Okta and external systems.

Resilience at Scale

Apply retry/backoff, rate-limiting, and pagination strategies to handle vendor API quirks, throttling, and intermittent failures gracefully across the dozens of concurrently supported integrations.

Security & Compliance

Ensure credential/secret handling, token exchange, and audit logging for provisioning operations meet Okta's security and compliance standards.

Product & Cross-Functional Alignment

Partner with PMs, support, and technical leads to prioritize new app integrations, resolve customer-reported connectivity issues, and participate in technical interviews/recruiting.

Operational Excellence

Participate in on-call rotations, troubleshoot production issues in integration pipelines, drive root-cause analyses, and improve observability/alerting for sync and provisioning jobs.

Code Quality & Technical Standards

Participate in code reviews, write thorough unit and functional tests, and maintain clear technical documentation.

Required Knowledge, Skills, and Abilities

Experience

5+ years of hands-on experience building and operating reliable, production-grade backend services.

Backend Expertise

Strong proficiency in Java and Spring Boot; comfortable owning services end-to-end from design through production support.

Distributed Systems

Experience with asynchronous job processing, scheduled/batch sync jobs, and event-driven patterns.

Data Management

Proficiency with relational databases (MySQL) and caching layers (Redis or similar).

Resilient Systems Design

Practical experience with retry/backoff strategies, rate-limiting, and handling pagination/throttling quirks from third-party APIs.

API Design

Experience designing and consuming RESTful APIs, including clients for third-party vendor systems with varying levels of API quality and documentation.

Problem Solving & Ownership

Ability to break down ambiguous integration requirements and independently drive a feature from design to production.

Decent Frontend Experience

While the role is backend-dominant, you should be comfortable building and modifying UI in React and JSP — well enough to independently deliver the frontend without relying on a dedicated frontend engineer.

Nice to Haves

• Experience with identity/IAM standards (SCIM, SAML, OAuth, OIDC) or directory services (AD, LDAP).

-Integration & Auth Protocols

Working knowledge of REST/SOAP API integration patterns and authentication standards such as OAuth2, SAML, or WS-Federation.

• Exposure to legacy protocol support (SOAP-based provisioning services) alongside modern REST/OAuth integrations.
• Familiarity with multi-tenant SaaS architectures or specialized compliance environments (e.g., FedRAMP/GCC-High).
• Experience with message brokers/queueing systems (Kafka) for asynchronous processing.
• Exposure to HTTP mocking/test-server frameworks (e.g., WireMock or equivalent internal mock-server tooling) for API-level testing.

Education

B.E./M.S. in Computer Science, Software Engineering, or related field, or equivalent practical experience.
