Rust Contract information
What is a Rust contract developer?
What types of projects and teams do Rust contract developers typically work on, and how is collaboration managed in these environments?
What are the key skills and qualifications needed to thrive as a Rust smart contract developer, and why are they important?
What is the difference between Rust Contract vs Rust Developer?
| Aspect | Rust Contract | Rust Developer |
|---|---|---|
| Required Credentials | Experience with Rust, contract law knowledge (if applicable) | Proficiency in Rust programming, coding certifications |
| Work Environment | Project-based, freelance or consulting | Full-time or part-time employment, in-house or remote |
| Industry Usage | Used in blockchain, smart contracts, and software projects | Develops software applications, systems, or tools |
The main difference is that a Rust Contract typically refers to a contractual role involving Rust skills, often project-based or freelance, focusing on specific deliverables. A Rust Developer is a full-time or part-time professional who writes and maintains Rust code within a company or organization. Both roles require Rust proficiency, but their work settings and responsibilities differ.

Job description
About the role:
Cobalt is seeking experienced penetration testers to contribute expert reasoning, technical problems, and evaluation data used to train and assess frontier AI models on security tasks.
This opportunity is suited to people who test systems for a living or have done so: penetration testers, red team operators, and serious bug bounty hunters, whether from consultancies, internal security teams, or independent practice.
You do not need prior experience in data annotation or AI research. What matters is that you can find and reason about real weaknesses in software and infrastructure unaided, and that you can document how you got there clearly enough for another practitioner to follow.
All work is performed against sandboxed environments, purpose-built targets, and model endpoints supplied by us or by the lab. We do not accept work performed against systems you are not authorized to test, and we do not accept material covered by a client agreement or obtained without authorization.
What you'll do:
Depending on the project, you may:
- Produce written testing traces, capturing how you form and test hypotheses, what you rule out and why, and how you arrive at a working approach, rather than only the end result
- Author novel security problems, capture-the-flag style challenges, and lab environments with verifiable success criteria
- Evaluate model-generated security content and code, ranking responses, explaining what makes the stronger one stronger, and identifying the specific step at which the technical reasoning breaks down
- Assess whether stated findings are supported by the underlying evidence, and identify inconsistencies between reported results and what the target actually does
- Design rubrics and partial-credit criteria for scoring multistep testing and remediation tasks
Projects follow their own guidelines, scope rules, and quality standards, and you will work with feedback from reviewers and lab research teams.
Required qualifications:
- Demonstrable penetration testing experience, evidenced by professional engagements, published vulnerability research or CVEs, a substantive bug bounty record, competitive CTF results, or comparable work
- Strong hands-on coding ability in at least one of Python, C, C++, Go, Rust, or JavaScript, sufficient to read unfamiliar codebases and write your own tooling rather than only running existing tools
- Depth in at least one area, for example web and API security, cloud and container security, network and infrastructure testing, mobile security, or binary exploitation
- Ability to explain each step of your reasoning clearly in writing, and to produce documentation another practitioner could reproduce
- Willingness to work strictly within defined scope and authorization, and to sign a confidentiality agreement covering project materials
Certifications such as OSCP, OSWE, OSEP, GPEN, or GXPN are useful but not required.
Why join Cobalt AI:
- Advance frontier AI where it counts. Apply your security expertise to data that frontier labs cannot obtain any other way, where your judgment directly shapes how the next generation of models reasons about security.
- Grow professionally. Expand your influence through evaluation projects, advisory roles, and research collaborations, while developing a working understanding of how frontier models are trained and assessed.
- Work with a top-tier network. Collaborate with security engineers and researchers from leading organizations on high-impact, flexible work.
- Set your own schedule. Flexible 10 to 40 hour weeks that fit around your existing engagements and your life.
- Competitive pay. Rates vary by project and are determined by a number of factors, including scope, skillset, and experience.
