Senior Full Stack Engineer - Infrastructure

Come join the company building the security operating model for the age of AI. AI has changed how data is used - and security must change with it. Cyera’s mission is to empower businesses to accelerate AI adoption by defining a holistic approach to securing AI, from data to access to models. Cyera provides a unified control plane that understands the relationships between data, access, and behaviors across people, systems, and AI. Backed by leading investors and working with a large and growing list of Fortune 1000 companies, we’re ushering in a new era of data and AI security.

As a Senior Full-Stack Engineer on Platform Infrastructure, you’ll build the shared platform that helps Cyera’s teams develop and operate customer-facing applications. The role spans the full stack, with most of the work in backend systems, cloud infrastructure, and operations.

Responsibilities



• Build and evolve shared platform foundations across the data lake, APIs, authentication, and authorization.
• Improve the foundations of our APIs by addressing data model and database challenges and reducing boilerplate, so teams can focus on business logic.
• Design, build, and operate shared infrastructure for customer-facing applications, including cloud infrastructure, webhooks, API gateways, CDNs, and CI/CD.
• Improve availability, stability, and performance across our web applications and services through sound architecture, production monitoring, and observability.
• Identify, document, and communicate technical improvements; help define clear interfaces, ownership boundaries, and standards across product teams.
• Collaborate closely with engineering teams - including backend, QA, and infrastructure - and with product, design, CSE, and SA partners to understand and challenge needs and translate them into practical technical solutions.
• Lead and contribute to cross-team engineering initiatives as an individual contributor. Clarify ambiguous goals, break work into practical plans, surface risks early, and keep stakeholders informed.

• At least 7 years of experience as a full-stack engineer.
• Deep knowledge of JavaScript and strong expertise in React, Vue.js, or a similar frontend stack.
• Experience with backend development technologies such as Node.js, TypeScript, Java, Scala, Python, Ruby, .NET, and similar technologies, and a willingness to learn new technologies.
• Experience building and operating customer-facing applications and services on fast-scaling, complex systems, with a focus on high availability, stability, performance, and security, including production monitoring and observability (such as Sentry).
• Strong experience with cloud infrastructure, authentication and authorization, CI/CD, and distributed systems.
• Mindset and care for high-quality feature delivery & communication with stakeholders.
• Experience with webhooks infrastructure, CDNs, and API gateways.
• Ability to lead projects independently, establish technical standards, communicate effectively, and keep stakeholders updated.
• Driven by impact and eager to create customer value.

Experience building platforms for multiple products or teams, scaling customer-facing APIs, or building and operating data lakes is a plus.
