Software Engineering Expert AI Training Data

Experience: 5.00 + years

Salary: USD 60000-84000 / year (based on experience)

Expected Notice Period: 15 Days

Shift: (GMT+05:30) Asia/Kolkata (IST)

Opportunity Type: Remote

Placement Type: Full Time Permanent position(Payroll and Compliance to be managed by: Theta)

(*Note: This is a requirement for one of Uplers client - Theta)

What do you need for this opportunity?

Must have skills required:

Next.js, or Node.js, react, Spring Boot, Django, Git, Github, JavaScript, Python

Theta is Looking for:

Theta partners with top AI labs to provide high-fidelity training data for the next generation

of coding models. We specialize in authentic software engineering workflows: building

features in existing codebases, refactoring legacy systems, and fixing critical bugs.

As a Software Engineering Expert at Theta, youll create the training data that teaches AI

models to think like real software engineers. Working with production-scale codebases

across multiple languages and frameworks, youll design complex, multi-file engineering

tasks that reflect the messy reality of professional software development. Youll work as an

AI engineer—building the evals and datasets that define frontier model capabilities and

shape the future of AI-assisted software development.

What Youll Do

• Design realistic software engineering tasks in production-scale codebases (both
  
  
  

open-source and private repositories) across multiple languages, frameworks, and

domains (backend, frontend, infrastructure, etc.)

• Create novel contributions to open-source repositories, developing new
  
  
  

features, refactoring opportunities, and authentic bug fixes that havent been

implemented

• Write comprehensive problem statements with detailed specifications that
  
  
  

mirror real-world product requirements and technical constraints

• Build reference implementations demonstrating correct solutions, including
  
  
  

handling edge cases and making appropriate architectural trade-offs

• Develop test suites that validate functionality across multiple files and
  
  
  

components, ensuring solutions work in the broader system context

• Document human reasoning traces that capture the thought process of an
  
  
  

experienced engineer: how to navigate unfamiliar code, debug issues systematically,

and make incremental progress on complex tasks

• Review and provide feedback on code and tasks created by other experts to
  
  
  

maintain rigorous quality standards, and collaborate on improving our data creation

infrastructure

What Were Looking For

• Professional software engineering experience. Youve worked in production
  
  
  

codebases, shipped features to users, and dealt with real-world engineering

complexity (or equivalent demonstrable experience)

• Strong programming fundamentals with proficiency in at least 2-3 languages
  
  
  

(Python, JavaScript/TypeScript, Java, C++, Go, or similar)

• Full-stack perspective. You understand how different parts of a system fit together,
  
  
  

from databases to APIs to frontend interfaces

• Comfort with ambiguity and messy code. You can navigate unfamiliar codebases,
  
  
  

reverse-engineer existing architectures, and work in realistic (imperfect)

environments

• Attention to detail. You write clear specifications, anticipate edge cases, and create
  
  
  

comprehensive test coverage

• Self-directed and reliable. You can manage your own schedule, meet deadlines,
  
  
  

and maintain high standards without constant oversight

• Excellent written communication skills. You can clearly explain technical
  
  
  

decisions, document your reasoning, and provide actionable feedback

Preferred Qualifications

• Experience with multiple programming paradigms and frameworks (e.g., React,
  
  
  

Next.js, Django, Spring, distributed systems frameworks)

• Significant contributions to open-source projects or experience reviewing pull
  
  
  

requests

• Experience working in large, legacy codebases with complex dependencies
  
  
  

Why Theta

• Autonomy and trust: We provide the platform, tools, and objectives—you control
  
  
  

how you design tasks. We rely on your judgment to identify compelling problems,

where models fall short, and how to push AI capabilities forward.

• Collaborative culture and direct impact: Work closely with our founding team in a
  
  
  

high-trust environment with quick feedback loops. Your insights shape our product

direction and inform model development at top AI labs.

• Continuous learning: Work across diverse codebases, frameworks, and domains,
  
  
  

ranging from React frontends to distributed systems to ML infrastructure. Every

project brings new technical challenges.

• Growth opportunities: Start by creating high-quality training data, then take on
  
  
  

leadership responsibilities like managing contributors, designing evaluation

frameworks, and building internal tooling.
