The Mission: Source.dev
Our founders spent over a decade at Google shaping the Android operating systems - building and shipping the software that now runs on billions of devices. They didn't just use Android; they led teams responsible for the Android Virtualization Framework, Security, and the Android Runtime (ART).
Through that journey, they saw a quiet but massive crisis: as device software grew in complexity, the tools used to build it remained stuck in the past. Today, a standard Android checkout exceeds 200GB of code, and builds can take hours. This "wait time" is the single biggest tax on innovation.
Source.dev was founded to reimagine software development workflows for device makers. We’re building a new generation of software tools that make building complex device software feel as simple as building a webpage - starting with SourceFS.
The Core Product: SourceFS
SourceFS is a high-performance virtual filesystem designed to turn multi-hour workflows into minutes.
- 10x Faster Builds: Intelligent caching and virtualization that only materializes files when they are actually needed.
- 10x Lower Costs: Enabling a standard 16-vCPU machine to outperform even a 128-vCPU machine.
- True Engineering Productivity: Replaying hundreds of thousands of build steps instantly when inputs match.
The Cultural Anchor: Own It
We operate with a high degree of trust and a shared value of End-to-End Ownership:
"We own our work end-to-end, from spark to finish. It’s about more than just tasks; it’s the dedication to see things through, staying curious to solve problems, thinking from first principles and ensuring we fix our customer’s problems in the best possible way.”
The Role: Scaling the Backbone of Modern Development
We are looking for an Site Reliability Engineer (SRE) to join our world-class team. This isn't just an operational "maintenance" role; you will be software-engineering the engine that powers tens of thousands of daily builds, ensuring our platform is as resilient as it is rapid.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you

Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What You’ll Work On:
- Distributed Systems Design: Architect and scale high-availability backend systems across the AWS ecosystem to meet global demand.
- High-Throughput Infrastructure: Build the foundation for CI/CD, developer environments, and AI workloads—supporting a massive volume of builds every single day.
- Optimization Strategy: Develop advanced autoscaling, multi-layer caching, and storage strategies that balance peak performance with cost efficiency.
- Operational Excellence: Own the observability and reliability of the platform, ensuring we maintain a "gold standard" of uptime and system health.
- Developer-Centric Tooling: Create sophisticated monitoring and internal systems that make managing infrastructure at scale feel effortless for both our team and our customers.
Ideal Candidate Profile:
- Coding-First SRE: You are a software engineer at heart with a strong programming foundation. You write clean, production-grade code, build robust internal tools, and treat infrastructure challenges as software problems.
- The AWS Expert: You have a deep, practical mastery of AWS, moving fluently between compute, networking, storage, and IAM.
- Automation First: You believe that manual work is a bug. You have extensive experience with Infrastructure as Code, specifically Terraform.
- Scale-Hardened: You come from an SRE or Production Engineering background, having navigated the unique challenges of running large-scale distributed systems in the wild.
- The Orchestrator: Skilled in Kubernetes and EKS, knowing exactly how to squeeze the best performance out of containerized workloads.
- Systems Thinker: You have a sharp eye for trade-offs, understanding how to navigate the delicate balance between performance, scalability, and cost.
- Our Tech Stack: We do development in Rust & Python. You should have strong coding experience in either Python, C++, Java (or similar modern languages). Prior Rust experience is NOT required, but strong willingness and excitement to learn is.
- Low Ego, High Impact: Beyond being a brilliant engineer, you are a thoughtful and empathetic teammate—someone who leads with kindness and values the success of the group.
- Feedback Culture Champion: You embrace feedback and provide it thoughtfully; you see open, honest communication as the foundation of great teamwork.
