About this Role
What You'll Do
- Design, build, and optimize high-performance systems in Rust that power AI data pipelines and evaluation workflows
- Develop backend services and tooling for large-scale data annotation, validation, and quality control
- Improve reliability, performance, and memory safety across existing Rust codebases
- Collaborate with data, research, and engineering teams to support model training and evaluation workflows
- Identify bottlenecks and edge cases in data and system behavior — then implement scalable, production-ready fixes
- Participate in synchronous design reviews to iterate on architecture and implementation decisions
About the Role
What if your systems programming expertise could directly shape the infrastructure behind some of the world's most advanced AI models? We're looking for a Senior Rust Engineer to build and optimize the high-performance data pipelines, annotation tooling, and evaluation systems that leading AI labs depend on to train and improve next-generation models. This is a fully remote contract role with serious technical depth. You'll be working on real production systems — not toy projects — alongside research and engineering teams at the frontier of AI development.
- Organization: Alignerr
- Type: Hourly Contract
- Location: Remote
- Commitment: 20–40 hours/week
Who You Are
- 5+ years of professional experience writing production-grade Rust
- Strong systems programming foundation — you think carefully about performance, concurrency, and memory safety
- Proven experience building backend services, developer tooling, or data pipelines
- Clear, direct communicator — written and verbal — comfortable working across technical and research teams
- Able to commit 20–40 hours per week with consistency and reliability
Nice to Have
- Prior experience with data annotation systems, data quality pipelines, or model evaluation infrastructure
- Familiarity with AI/ML workflows, model training, or benchmarking pipelines
- Experience with distributed systems design or developer tooling at scale
- Exposure to Go, Python, or C++ in a systems context
Why Join Us
- Work directly with leading AI labs on real, production-grade infrastructure that matters
- Fully remote — work from anywhere, on a schedule that fits your life
- Freelance autonomy with the structure and focus of high-impact, technically challenging work
- Contribute to systems that shape how the world's most advanced AI models are built and evaluated
- Potential for ongoing engagement and expanded scope as projects grow
Requirements
- Fluent proficiency in English (Written & Verbal)
- Reliable high-speed internet connection
- Bachelor's degree or equivalent professional experience
- Demonstrated expertise in Software Engineering

Frequently Asked Questions
What is the assessment actually like?
Notoriously strict. Alignerr uses TestGorilla for role-specific timed tests — a blank coding environment for engineers, rigorous grammar and fact-checking for writers. There is almost no hand-holding. The critical catch: this is essentially a one-shot process. Fail or abandon the assessment, and you are typically locked out of that role permanently with no option to retake.
How quickly can I start earning after I pass?
Not immediately. Even after passing the assessment and completing identity verification (via Persona) and billing setup (via Deel), you may sit in a waiting pool for weeks or months. You only start earning when a project matching your specific skills launches and you are officially assigned. Do not plan around Alignerr income until you are actively on a project.
Is there a community?
Yes — and it is one of Alignerr's genuine strengths. Once assigned to a project, you are added to Slack channels where you can ask questions, get rubric clarifications from admins, and talk to other AI trainers. This is rare in AI training and makes a real difference when guidelines are ambiguous or change mid-project.
What does the work actually look like?
It is practical, hands-on data work. You might be recording short videos, categorizing images, rating text responses, or analyzing data. The tasks are designed to be short and distinct—typically 5-60 minutes per task.
How flexible is the schedule?
Extremely. This is true "log in and work" flexibility. You can usually work for 20 minutes or 4 hours depending on your availability. There are rarely minimum hour requirements, making it ideal for side income.
Is there an interview?
Usually, no. Hiring for these roles is almost entirely based on passing an automated assessment or "qualification" task. If you pass the test, you get access to the work.
What is the barrier to entry?
Alignerr is known for difficult technical assessments. You must pass a timed test in your specific domain (e.g., Python, Physics, or Language) before you are eligible for any paid projects.
