Senior Application Engineer, Workplace Technology

Why Mozilla?

Mozilla Corporation is the non-profit-backed technology company that has shaped the internet for the better over the last 25 years. We make pioneering brands like Firefox, the privacy-minded web browser. Now, with more than 225 million people around the world using our products each month, we’re shaping the next 25 years of technology and helping to reclaim an internet built for people, not companies. Our work focuses on diverse areas including AI, social media, security and more. And we’re doing this while never losing our focus on our core mission – to make the internet better for people. 

The Mozilla Corporation is wholly owned by the non-profit 501(c) Mozilla Foundation. This means we aren’t beholden to any shareholders — only to our mission. Along with thousands of volunteer contributors and collaborators all over the world, Mozillians design, build and distribute open-source software that enables people to enjoy the internet on their terms. 

About this team and role:

The role is part of the IT Function within the broader Mozilla Infrastructure team. The IT team supports ERP Services, Workplace services, Service-Desk and On-Prem DC Services across the organization aligned with the mission to build a safe & secure internet. As a Software (Application) Engineer in the newly formed Workplace technology team, you’ll help design, build, and maintain the systems and automations that power Mozilla’s workplace technologies — from collaboration and AI productivity tools to identity and access workflows. You’ll manage day-to-day administration, develop scripts and integrations, and contribute to projects that improve reliability, security, and user experience. This role is hands-on and growth-oriented, offering opportunities to deepen your technical expertise while shaping how Mozillians work and collaborate.

Note : You don’t need to meet every listed qualification to be considered — we value diverse experiences and learning potential.

What you’ll do: 

• Design, build, and maintain scripts, APIs, and workflow automations that power key workplace systems — collaboration tools (Google Workspace, Slack, Zoom, Atlassian) and identity platforms (Okta).
• Develop lightweight services or integrations that connect collaboration, GenAI-tools (OpenAI, Claude, Gemini) and internal systems, enabling agentic flows (e.g., virtual assistants, workflow agents) that reduce manual work and improve user experience.
• Implement monitoring, logging and observability for automation and AI workflows; troubleshoot issues and uncover opportunities for reliability, scalability, and cost-efficiency.
• Contribute to the evolution of secure onboarding, off-boarding, and mover workflows across access, permissions and SaaS tools — with automation and safe agentic handoffs where appropriate.
• Collaborate with IT, Security, and People teams to ensure identity, data, and compliance standards (SSO, DLP, classification) are deeply embedded through automation and script-driven guardrails.
• Participate in pilot projects for new AI and productivity capabilities: integrate LLMs & agents, track usage/adoption metrics, build flows that assist users (e.g., knowledge-agent, document summarizer).
• Contribute to the code-review process, documentation of shared libraries for workflows/agents, and build a library of integration templates for reuse across the team.
• Partner with senior engineers to modernize workplace systems through scalable architecture, API-first design, and intelligent agentic workflows.

What you'll bring:

• 4–6 years of experience in software engineering, systems integration or workplace technology development, with a focus on automation or scripting.
• Proficiency in one or more programming/scripting languages (Java, Go, Python, JavaScript/Apps Script, Bash, PowerShell) and comfortable with RESTful APIs, webhooks, and integration frameworks.
• Familiarity with SaaS platforms (Google Workspace, Slack, Zoom, Atlassian) and interest in agentic/AI workflows (LLMs, agents, prompt pipelines).
• Understanding of IAM/SSO (Okta, SAML/OIDC/SCIM) or a willingness to grow in this area; experience automating provisioning/access is a plus.
• Experience or curiosity about CI/CD, workflow orchestration, and building self-service delivery models that leverage agents or automation.
• Strong troubleshooting, documentation and cross-functional communication skills; comfortable collaborating with non-technical partners and translating automation into tangible operational gains.
• A growth mindset: you embrace learning new AI technologies, care about user experience, and seek to improve systems through intelligent workflows.
• Interest in building agentic flows (for example: bots that triage tickets, summarize documents, assist user tasks) and integrating them responsibly into workplace systems.
• Commitment to our values:
• Welcoming differences
• Being relationship-minded
• Practicing responsible participation
• Having grit

What you’ll get:

• Generous performance-based bonus plans to all eligible employees - we share in our success as one team
• Rich medical, dental, and vision coverage
• Generous retirement contributions with 100% immediate vesting (regardless of whether you contribute)
• Quarterly all-company wellness days where everyone takes a pause together
• Country specific holidays plus a day off for your birthday
• One-time home office stipend
• Annual professional development budget
• Quarterly well-being stipend
• Considerable paid parental leave
• Employee referral bonus program
• Other benefits (life/AD&D, disability, EAP, etc. - varies by country)
