🛠️ Engineering Culture Guide¶

🏛️ Ownership & End-to-End Accountability

• Every engineer is responsible from idea through design, implementation, release, and long-term maintenance.
• We anticipate the impact of our work: on users, on privacy, on system integrity, and on the brand.
• We own the problems and the outcomes.

🔒 Privacy by Default

• Our products are built around giving control to the user. We apply the same mindset in how we build.
• We question every assumption: "Does this component gather data? Could it be misused? How can it fail?"
• Security, transparency, and openness are baked in—not added later.

🚀 Iterate with Impact

• We ship early, learn fast, and improve continuously.
• We use data, feedback, and metrics from real usage to guide our decisions — always in ways that respect privacy and uphold user trust.
• Perfection isn’t the goal — progress is. But we don’t sacrifice craftsmanship for speed.

💬 Clear Communication & Team Collaboration

• Transparent design, timely code reviews, open discussions: we surface issues early and clearly.
• We embrace constructive feedback: code reviews are opportunities to learn and teach, not gatekeeping.
• We cross disciplines: firmware, OS, hardware, and UI — all parts of one system.

🔧 Craftsmanship & Maintainability

• It’s not enough to make something work — we make it work well, safely, and sustainably.
• Readable, testable, documented code; modular architectures; clear ownership of interfaces and dependencies.
• We assume the product will still be in support for years — we build for longevity.

🌱 Learning & Growth

• We push ourselves and each other to stay curious, open, and adaptable.
• Mistakes happen. We learn from them, share the lessons, and improve.
• We support experimentation and prototyping — some ideas won’t make it, but they’ll teach us.

🔍 Code Reviews

• Review requests are concise and focused on design, correctness, performance, maintainability, and security.
• Reviewers respond in a timely manner; authors update respectfully.
• We keep reviews positive and forward-looking: "How can we make this better?" not "Who broke it?".

👥 Pairing & Mentorship

• Pair programming is encouraged for onboarding, solving tricky problems, or transferring knowledge.
• Senior engineers actively mentor others; every engineer plays both roles: mentee and mentor.

📝 Documentation & Decision Records

• We document architecture decisions: why we chose a path, what trade-offs we accepted.
• We keep user-facing and internal docs clear and up-to-date.
• "Who changed this and why?" is always answerable.

🧯 Blameless Post-mortems

• When things go wrong, we hold a blameless retrospective.
• Focus on systems, processes, and triggers — not assigning fault.
• Identify root causes, define action items, follow through, and share learnings.

🚑 On-call & Reliability

• Our mobile systems must be reliable. When an engineer is on-call, they should be well-prepared, not surprised.
• We rotate fairly, document escalation procedures, monitor key metrics, and ensure after-hours work remains sustainable.

💡 Innovation Time & Hack Weeks

• We allocate time for engineers to explore new ideas: features, tools, open-source contributions, and community integrations.
• These experiments feed innovation and keep our products fresh while aligning with our privacy-first mission.

⚙️ Automate First

• Manual scripting is a signal: if it’s worth doing once, it’s worth automating.
• CI/CD pipelines, testing, deployments, and monitoring are built early and improved continuously.

🔐 Security & Privacy Built-In

• Threat modeling, compliance, and audits are integral to every release.
• We validate open-source paths, hardware footprints, data flows, sensor access, and bootloader controls.
• Privacy features — like blocking trackers — are core parts of the product, not optional extras.

⚡ Performance & Scalability Mindset

• Efficiency matters: processing, power, latency, and bandwidth all shape the user experience.
• We design for growth — across devices, regions, and OS versions.

📖 Open Source & Transparency

• We believe in transparency: our stack, our decisions, and our builds.
• We engage the community, respond to audits, and invite scrutiny. Transparency builds trust — both in our products and our culture.

🛡️ Psychological Safety

• Everyone has a voice. All ideas are welcome.
• We separate role from input: junior engineers ask questions; senior engineers listen.
• We treat failures as learning opportunities, not blame events.

🌍 Diverse Perspectives

• The best solutions come from varied viewpoints. We encourage representation across disciplines and backgrounds.
• We value clarity over jargon and empathy over ego.

🎓 Mentorship & Knowledge Sharing

• Regular tech shares, brown-bag sessions, and internal meetups promote collective learning.
• Engineers take time to teach, document, and pair — growth is continuous.

🎉 Recognition & Feedback

• We celebrate engineering wins — big and small.
• We give timely feedback: peer-to-peer and manager-to-engineer.
• We recognize effort and growth, not just outcomes.
