Senior Backend Engineer

Unixi is rethinking Identity and Access Management (IAM) for the modern enterprise. Our Universal SSO approach enables organizations to control access across SaaS applications without the heavy integration burden and cost model of legacy IAM platforms. Combined with SaaS discovery, governance, and growing lifecycle capabilities, Unixi gives security and IT teams a new way to manage identity across the real SaaS world.

With the introduction of Lifecycle Management (LCM), Unixi is evolving into a broader IAM platform, one that not only helps organizations control access, but also automate identity operations, govern SaaS usage, and manage user lifecycle workflows across their environment.

We’re a fast-growing, well-funded cybersecurity startup backed by leading investors and industry veterans, and we’re looking for a Senior Backend Engineer, Identity Platform to help us build the core systems behind the platform.

As a Senior Backend Engineer at Unixi, you’ll work on deep backend and product challenges at the heart of modern identity. You will design and build the services, APIs, and internal systems that power authentication, policy enforcement, lifecycle workflows, SaaS integrations, and the operational backbone of our platform. This is a high-impact role for an engineer who wants to build real product, own production systems, and help shape the technical foundations of a new kind of IAM company.

This is not a narrow implementation role. We are looking for someone with strong backend fundamentals, sound engineering judgment, and the ability to move from architecture and design all the way to production.

Responsibilities

• Design, build, and maintain scalable backend services, APIs, and internal systems that power Unixi’s identity platform.
• Own features end to end – from technical design and implementation to testing, deployment, and production support.
• Build core platform capabilities across authentication, policy enforcement, SaaS discovery, lifecycle workflows, and enterprise integrations.
• Work on complex backend challenges involving scale, reliability, performance, data modeling, and multi-system orchestration.
• Design robust integrations with external platforms such as SaaS applications, identity providers, and enterprise systems.
• Collaborate closely with product, frontend, and platform engineers to translate product requirements into strong backend architecture.
• Improve system observability, maintainability, testing practices, and operational excellence across the backend stack.
• Contribute to technical direction and help shape the architecture of a growing cybersecurity platform.
  
  

• 5+ years of backend software engineering experience.
• Strong hands-on experience with Python and excellent backend engineering fundamentals.
• Experience designing and building production-grade backend systems and APIs.
• Strong understanding of distributed systems, asynchronous processing, and backend reliability concerns.
• Experience working with relational databases; PostgreSQL experience is a strong advantage.
• Experience integrating with external APIs and building reliable service-to-service workflows.
• Experience working in cloud production environments such as GCP, AWS, or Azure.
• Familiarity with containerized deployment environments; Kubernetes experience is a plus.
• Strong debugging and problem-solving skills, with a clear production ownership mindset.
• Strong communication skills, high ownership, and the ability to thrive in a startup environment.
  
  

• Experience with authentication, authorization, SSO, SAML, SCIM, lifecycle management, or related identity technologies.
• Experience with Google Cloud and cloud-native backend systems.
• Interest in solving hard enterprise security problems with elegant product and engineering solutions.
  
  

• Experience working on products that include a browser extension layer, or backend systems tightly coupled to browser behavior, authentication flows, and web session management – big advantage.
• Experience in IAM, cybersecurity, SaaS management, enterprise networking or enterprise infrastructure domains – big advantage.
• Experience building security-sensitive or reliability-critical backend systems.
• Startup experience, especially in early-stage or scaling product companies.
