[Hiring] Senior Engineer @Simbian Inc

Role Description

We are looking for a Senior Engineer (Platform) to build the enterprise platform that Simbian's AI agents run on. This role is about delivering platform infrastructure that enterprise customers can depend on - multi-tenant architecture, access control, release quality, and the engineering practices that make all of it sustainable at scale.

You will design and build core platform features, ship on a predictable cadence, and raise the engineering bar across the team. You'll work closely with product, security, and AI engineering teams to ensure the platform keeps pace with a rapidly evolving product.

What You'll Do

• Platform Engineering
  • Design and build multi-tenant platform capabilities that securely isolate and serve multiple enterprise customers at scale.
  • Implement and evolve RBAC and access-control systems across the platform.
  • Own platform features end-to-end - from architecture and implementation through deployment, monitoring, and iteration in production.
  • Build for reliability, observability, and maintainability from the start.
• Delivery & Release Quality
  • Ship on a regular release cadence; keep delivery predictable and visible to the team.
  • Maintain high code quality: participate actively in design reviews, hold the bar in code reviews, and write well-tested code.
  • Partner with the SDET on testability - ensure new features are built in ways that make automated testing straightforward.
  • Identify and reduce sources of unpredictability in the release process.
• Cloud & Infrastructure
  • Build and deploy services on AWS using Docker and Kubernetes.
  • Work with CI/CD pipelines to make deployments reliable and fast.
  • Design systems with strong observability, traceability, and monitoring so failures are easy to detect and debug.
• Cross-functional Collaboration
  • Work across a full-stack web codebase; contribute on both backend and frontend where needed.
  • Partner with product, AI engineering, and security teams to turn platform requirements into working systems.
  • Contribute to architectural decisions as the platform evolves and scales.

Qualifications

• 6–10 years of software engineering experience, with a strong track record in backend or full-stack platform development.
• Experience building multi-tenant or SaaS platforms and understanding the tradeoffs involved in getting isolation, performance, and access control rights.
• Accountable for delivery and consistent shipping.
• Ability to raise the engineering bar through useful code review feedback and early design issue identification.
• Comfortable operating with autonomy - scoping work, making tradeoffs, and driving execution without needing detailed specs.
• Enjoy working across a codebase and collaborating closely with teammates across disciplines.

Requirements

• 6–10 years of professional software engineering experience.
• Strong backend development experience, preferably with Python; full-stack experience a plus.
• Proven experience building multi-tenant or SaaS platforms at scale.
• Hands-on experience with RBAC or similar access-control systems.
• Solid grasp of CI/CD pipelines and cloud deployment on AWS with Docker and Kubernetes.
• Strong fundamentals in distributed systems, APIs, and backend architecture.
• Ownership mindset and ability to drive features from zero to production.
• Strong instincts around code quality, testability, and engineering practices.

Bonus / Great to Have

• Experience with security products - SIEM, SOAR, EDR, NDR, or similar enterprise security platforms.
• Experience working with LLM-powered or agentic systems.
• Frontend experience with React.
• Experience with agent observability, tracing, or production monitoring.
• Strong academic background in Computer Science or a related field; graduates from IITs or other top-tier engineering institutions preferred.

Benefits

• Build the enterprise platform that an AI-first cybersecurity product runs on - from the ground up.
• Work at the intersection of AI, cybersecurity, and distributed systems.
• Own meaningful platform problems end-to-end and see your work go directly into production.
• Work directly with founders, researchers, security experts, and engineering leaders.
• Be part of an early team where your technical decisions and ideas can have outsized impact.
• Ship fast, learn fast, and build systems that matter.
