People Technology Application Engineer

Responsibilities

• Build custom app extensions and tailored UI/UX workflows utilizing Workday Extend, Python frameworks, and modern low-code/no-code platforms.
• Follow our "simplify first, then automate" philosophy to eliminate point-to-point manual processes and technical debt. Research, prototype, and deploy automated workflows and custom AI agents (e.g., using Google Vertex AI / Gemini Enterprise). You are curious about emerging technologies (like generative AI and automated agents) and know when they genuinely add business value.
• Embed strict access controls, data security, and compliance (GDPR) into all software architectures, ensuring responsible boundaries for handling employee data. You treat security, privacy, and system governance as fundamental engineering requirements.
• Establish clear software engineering practices, API specifications, and maintainable technical documentation so solutions can be easily supported and scaled. You move comfortably between technical architecture details and broad operational context.
• Collaborate closely with Core People Tech specialists, Data Engineers, Security, and HR functional leads to translate complex business needs into clean technical solutions. You start with the problem rather than forcing a specific technology, balancing speed with long-term code maintainability.
• Repetitive manual tasks and system friction are systematically eliminated through clean Python automation and custom app extensions.

Requirements

• 5+ years of software development, application engineering, or integration engineering experience in an international environment.
• Strong hands-on proficiency in Python (FastAPI/Flask), React, and web technology fundamentals (REST APIs, JSON, Webhooks, OAuth, SQL (Postgre)).
• In-depth knowledge of application security, fine-grained access management, and privacy-by-design principles.
• Excellent communication skills, strong problem-solving ability, and a drive to challenge requirements constructively to deliver scalable architectures.

Engineer application & integration solutions

Design, develop, and maintain custom applications, programmatic API integrations, webhooks, and middleware connecting Workday HCM with Greenhouse, Qualtrics, Docebo, Slack, and internal platforms.

Integration & Middleware Tech

Demonstrated experience with integration platforms (iPaaS), event-driven architectures, or middleware tools.

HRIS & Ecosystem Knowledge

Hands-on experience or familiarity with enterprise SaaS platforms (Workday APIs, Workday Extend, Studio, or similar cloud ecosystems).

What success will look like

• Workday and our broader SaaS ecosystem are connected through reliable, maintainable API integrations rather than brittle point-to-point fixes.
• Reusable application foundations, middleware, and documentation exist, allowing new People Tech features to be built faster.
• Security and privacy boundaries are seamlessly embedded into every deployed application and integration.
