MURAL's Admin & Identity and Access Management (IAM) team is seeking a Senior Software Engineer to design and ship identity and access capabilities end-to-end. You will own authentication & authorization, Single Sign-On (SSO), Multi-Factor Authentication (MFA), user provisioning (SCIM), session management, and the core permission model that powers roles and access control across companies and workspaces. You will also own the enterprise administration experience—the configuration and controls that company and workspace admins use to manage their organizations and users.
As a Senior Engineer, you will design and ship these capabilities from identity primitives like the permission model and authentication flows to the admin surfaces enterprise customers use daily. You will own complex technical initiatives, influence platform and security best practices, and collaborate closely with Product, Design, and Infrastructure to deliver secure experiences that feel simple and intuitive.
Key responsibilities include:
- Build and evolve core identity and access systems powering authentication & authorization, SSO, user provisioning, session management, and permissions across Mural
- Build and evolve the enterprise administration experience, including company and workspace configuration, user and content administration, billing, and internal admin tooling
- Collaborate with cross-functional partners to design and ship secure, intuitive access and administration experiences
- Prototype, implement, and maintain Admin & IAM platform features, contributing as a technical expert and supporting teammates through collaboration and mentorship
- Own technical initiatives from design through implementation, rollout, and operational support
- Build flexible, observable, and maintainable solutions while being accountable for security, quality, performance, and reliability
- Use AI tools as part of your fundamental workflows to improve productivity, code quality, and system understanding
- Contribute to technical design discussions, provide thoughtful code reviews, mentor teammates, and continuously improve engineering work quality
- Contribute to continuously improving team processes and engineering best practices
You will report to an Engineering Manager and work with a small, focused team in a remote-first environment, with the option to work from the Buenos Aires office.
REQUIREMENTS:
- 4+ years building and shipping large-scale production software as part of an agile engineering team
- Experience learning new technologies, platforms, and stacks, and getting productive quickly in large, existing codebases
- An outcome-oriented and pragmatic interest in using AI-driven development practices to improve productivity, code quality, and system understanding
- Strong experience building backend systems and APIs using Node.js, TypeScript/JavaScript, MongoDB, or comparable technologies
- Hands-on experience building production user interfaces with React and modern frontend patterns
- Proven ability to plan and deliver technical projects iteratively, balancing speed, quality, and long-term maintainability
- Strong collaboration and communication skills, with the ability to work effectively across product, design, security, and engineering partners
- Experience working in a fast-moving or growth-stage environment, adapting to evolving requirements and priorities
- Domain experience with identity and access management concepts such as authentication flows, authorization models, roles and permissions, SSO, SCIM provisioning, or session management
- Experience building enterprise administration or B2B SaaS configuration surfaces, such as org management, billing, or admin dashboards
