Staff/Principal Platform Engineer






San Francisco, CA, US


Udemy's platform engineering team develops and supports software frameworks, services, tools, and processes that enable Udemy to support over 30 million students and 42,000 instructors in more than 190 countries globally.  Our platform team is responsible for a wide swath of the software and infrastructure we build on top of including 3rd party frameworks (like Django), services (and microservices), APIs, authentication, security, build, message queues, task runners, versioning, and performance.  We take on this work as well as the internal education and training associated with it.
We are looking for a senior software professional with proven experience in developing robust, scalable, and secure systems in an agile culture that ships dozens of changes every day. We need this person to have a healthy interest in the security responsibilities of our platform team. We would be thrilled if you have relevant security experience already, but we are happy for you to learn on the job as well.

Here’s what you’ll be doing:

      • Design, develop, test, document, release, and monitor features in libraries and services that support Udemy's web and mobile applications.
      • Plan, organize, and get work done in 2-week sprints.
      • Participate in code reviews.
      • Mentor team members in robust, scalable, and secure software development best practices and processes.
      • Lead by example and contribute to a team culture that values quality while fostering innovation.
      • Research and evaluate new technologies that may improve our processes or code bases.
      • At times, function as a technical lead for various projects/tasks. This may involve some project, resource, and deployment planning in addition to software engineering responsibilities.
With your interest in security, you will over time:
    • Improve features in and around authentication and authorization.
    • Contribute to automating security checks and tests that plug into developer workflows, build pipelines, and continuous integration (CI).
    • Help educate and train Udemy's engineering staff on best practices in software development.
    • Collaborate with other engineers, product managers, and designers, as well as Udemy's information security, operations, legal, and compliance teams to develop, document, and implement processes and tools to keep Udemy's applications and systems secure, while meeting business goals as well as regulatory requirements.

We’re excited about you because you have:

    • At least 7 years of professional software development experience.
    • Hands on experience designing, developing, reviewing, and deploying robust, scalable, and secure software systems and services.
    • Knowledge of common software, system, and internet security considerations including: OWASP top 10, authentication and authorization, as well as common vulnerabilities and threats.
    • Knowledge of object-oriented design and computer science fundamentals (data structures, algorithms).
    • Experience at least one or more scripting languages, like Javascript, Python, PHP, or Ruby as well as one of Java, Kotlin, C++ or C#.
    • Experience with Continuous integration and delivery (CI/CD) systems.
    • Knowledge of RDBMS (e.g. MySQL) and SQL.
    • Experience with Message and other queueing systems (e.g., RabbitMQ, Kafka)
    • Experience with ORMs (preferably Django, but Rails, Hibernate, JPA or others are OK).
    • Knowledge of web application technologies including HTTP, HTML, CSS, and JavaScript.
    • Experience with IP Networking (TCP/IP, HTTP), Public cloud (ideally AWS) and Linux/unix.
    • Knowledge of testing methods, including unit and integration tests.
    • The ability to learn, work with, and migrate, existing code bases.

Nice to haves:

    • Management of small teams.
    • Single-sign-on (SSO) systems and tools.
    • Web video standards and technologies.
    • Kubernetes, Docker, containers and container security.
    • Experience with attack trees.
    • Data encryption and cryptographic standards and technologies.
    • Data privacy and compliance frameworks, including GDPR.
    • Common industry standards and regulations like ISO27000, SOC2, and SOX.
    • Working with teams in remote locations (e.g., Ireland, Turkey).
    • Contributing to public open source project(s) and involvement in local technology communities.
