Stellenbeschreibung


At TripleTen , we’re creating innovative learning products that empower people to master IT professions like software engineering, data science, business intelligence, and QA — no matter their prior experience. Our AI-driven and thoughtfully designed platform helps students build real skills and access meaningful career opportunities. We're passionate about making education accessible, engaging, and empowering for everyone.

We are looking for a Senior Backend Engineer to lead the evolution of our multitenant infrastructure and access management services. This isn't just about writing tickets; you will be a core architect of the systems that ensure our platform remains secure, scalable, and robust.


The Tech Stack

  • Core: Python 3.x (FastAPI)
  • Data & Messaging: Postgres, Kafka
  • Infrastructure: AWS, Kubernetes, Helm
  • CI/CD: GitLab CI
  • Patterns: DDD, Onion Architecture




Brand:
TripleTen

What you will do:


  • Architect & Build: Design and maintain high-performance server-side applications with a focus on multitenancy and IAM.
  • Product Partnership: Share end-to-end ownership of the product lifecycle with your Product Manager — from initial discovery and requirement sharpening to deployment.
  • Technical Excellence: Implement DDD and Clean Architecture principles to keep our codebase maintainable and easy to extend.


What we can offer you:


  • Fully remote, full-time role with flexible hours to balance work and personal life.
  • Paid parental leave and paid sick leave to ensure your well-being.
  • A supportive and inclusive team where empathy, respect, and open communication are valued.
  • Opportunities for learning, mentorship, and professional growth.
  • Competitive compensation with transparent working conditions.
  • A suite of thoughtfully chosen collaboration tools: Miro, Notion, Google Workspace.


*At this time, we are unable to offer H-1B, L-1A/B sponsorship opportunities.


**This job description is not designed to contain a comprehensive listing of activities, duties, or responsibilities that are required. Nothing in this job description restricts management's right to assign or reassign duties and responsibilities at any time.

**TripleTen is an equal employment opportunity/affirmative action employer and considers qualified applicants for employment without regard to race, color, religion, sex, national origin, age, religion, disability, marital status, sexual orientation, gender identity/expression, protected military/veteran status, or any other legally protected factor.



  • Multitenancy Expert: You understand the nuances of data isolation, tenant-specific configurations, and the complexities of shared infrastructure.
  • Deep Roots in Statically Typed Languages: You have an extensive background in C#, Java, Kotlin or similar languages. You understand the structural discipline, strict typing, and design patterns that these ecosystems demand.
  • Ready to Master Python: Our primary stack is Python 3.x/FastAPI. You don't need to be a Python expert on day one, but you are eager to translate your architectural expertise into the Python world and are a fast enough learner to hit the ground running.
  • Architecturally Disciplined: You don’t just "write code"; you apply DDD and Clean Architecture because you’ve seen what happens to "spaghetti" projects at scale.
  • Testing Advocate: You believe that code isn't finished until it’s tested (Unit, Integration, and ideally TDD).
  • Collaborative: You value Agile principles and enjoy investing in team processes, mentoring, and collective growth.
  • Fluent in English: Able to articulate complex technical trade-offs to both engineers and stakeholders.
