Who we are

The Tor Project, Inc. (TPI) is a 501(c)(3) nonprofit organization advancing human rights and freedoms by creating and deploying free and open source anonymity and privacy technologies. TPI's team is committed to and passionate about our mission. We currently have a team of over 65, along with thousands of volunteers who contribute to our work. TPI is funded by government research and development grants, as well as individual, foundation, and corporate donations.

Overview of the role

We are seeking a Senior Android Engineer to serve as the lead for a newly formed mobile team. This role provides technical leadership across Tor’s Android products, including Tor Browser for Android, while establishing sustainable ways of working for a growing team.

You will lead technical direction and delivery for the mobile team across multiple related products, working closely with product design, desktop browser, and other teams. While this is a lead role, you are expected to remain hands-on in architecture and development work. This role is accountable for Android technical direction and delivery across Tor’s mobile products.

Tor operates in a high-risk domain where technical decisions may directly impact user safety, privacy, and anonymity. Success in this role requires recognizing when decisions intersect with specialized domains and working closely with experienced Tor contributors to inform sound, responsible mobile decisions.

What You’ll Do

• Lead planning and coordination for development across Tor’s mobile products
• Translate organizational and product priorities into clear, capacity-aware mobile plans and milestones
• Take technical ownership of Android architecture, performance, and long-term maintainability
• Contribute hands-on development, particularly in complex or cross-cutting areas of the codebase
• Review and guide code contributions, setting expectations for quality, security, and correctness
• Identify and surface technical risks, dependencies, and tradeoffs early, to support informed decision-making
• Mentor and support Android engineers, building technical judgment, ownership, and sustainable development practices
• Collaborate across teams to align planning and delivery, while ensuring shared technical decisions reflect Android/mobile constraints and long-term viability.

Who you are

• A senior Android engineer with experience delivering and maintaining large, long-lived applications using Kotlin and Java
• Deep familiarity with Android application architecture, build systems, and release processes
• Comfortable owning outcomes end-to-end, from shaping scope and technical approach through delivery
• Able to make pragmatic architectural decisions that balance correctness, privacy, performance, and long-term maintainability
• Hands-on in your work, contributing directly to development, code reviews, and technical problem-solving
• Experienced mentoring and supporting engineers through guidance, review, and shared ownership
• Clear and thoughtful communicator, including in asynchronous collaboration
• Comfortable coordinating across teams with sufficient understanding of browser architecture to reason about tradeoffs and downstream consequences of shared technical decisions
• Motivated by Tor’s mission and aligned with building privacy-preserving software that serves real users
• Preferred but not required:
  • Experience contributing to or maintaining open source software, including constructive engagement with users and other contributors in public technical spaces
  • Experience working in large, or legacy Android codebases
  • Familiarity with browser-based applications, or Firefox-derived codebases
  • Experience working on privacy, security, or anonymity-focused software
  • Familiarity with Rust, C++, or cross-language systems
