What is a 1099 software developer contractor?

A 1099 Software Developer Contractor is a self-employed software developer who provides services to companies as an independent contractor rather than as a traditional employee. They typically work on a contract basis, meaning they are responsible for managing their taxes, benefits, and business expenses. These professionals have flexibility in choosing projects and clients but must also handle their invoicing and financial obligations. Since they do not receive employee benefits, they often negotiate higher rates to compensate for additional costs.

What are the key skills and qualifications needed to thrive as a 1099 software developer contractor?

To thrive as a 1099 Software Developer Contractor, you need strong programming skills in languages such as Python, Java, or JavaScript, a solid understanding of software development lifecycles, and a portfolio of delivered projects. Familiarity with version control systems like Git, cloud platforms (e.g., AWS or Azure), and sometimes relevant certifications (such as AWS Certified Developer or Microsoft Certified: Azure Developer Associate) is often required. Excellent time management, proactive communication, and problem-solving abilities help set top contractors apart. These skills are critical because 1099 contractors must deliver high-quality solutions independently while effectively collaborating with remote clients across diverse projects.

What are some common challenges faced as a 1099 software developer contractor and how can they be managed?

A common challenge for 1099 Software Developer Contractors is balancing multiple clients and projects simultaneously while ensuring clear communication and meeting deadlines. You may also need to adapt quickly to various tech stacks and company cultures, since each client can have unique processes and expectations. Staying organized with project management tools, setting clear boundaries, and maintaining transparent communication are key to managing these challenges effectively. Embracing continuous learning and networking can also help contractors stay competitive and grow their client base.

Job description

About Us:
Based in San Francisco, California, Turing is the world’s leading research accelerator for frontier AI labs and a trusted partner for global enterprises deploying advanced AI systems.

Turing supports customers in two ways: first, by accelerating frontier research with high-quality data, advanced training pipelines, plus top AI researchers who specialize in software engineering, logical reasoning, STEM, multilinguality, multimodality, and agents; and second, by applying that expertise to help enterprises transform AI from proof of concept into proprietary intelligence with systems that perform reliably, deliver measurable impact, and drive lasting results on the P&L.

Project Overview:
As a Software Engineering evaluator, you will create cutting-edge datasets for training, benchmarking, and advancing large language models, collaborating closely with researchers. This includes curating code examples, providing precise solutions, and making corrections in Python, JavaScript (including ReactJS), C/C++, Java, Rust, and Go; evaluating and refining AI-generated code for efficiency, scalability, and reliability; and working with cross-functional teams to enhance enterprise-level AI-driven coding solutions.

What Does a Typical Day Look Like?
  • Working on AI model training initiatives by curating code examples, building solutions, and correcting code in Python, JavaScript (including ReactJS), C/C++, Java, Rust, and Go.
  • Evaluate and refine AI-generated code to ensure that it is efficient, scalable, and reliable.
  • Collaborate with cross-functional teams to enhance AI-driven coding solutions against industry performance benchmarks.
  • Build agents that can verify the quality of the code and identify error patterns.
  • Hypothesize on steps in the software engineering cycle (prototyping, architecture design, API design, production implementation, launch, experiments, monitoring, operational maintenance) and evaluate model capabilities on them.
  • Design verification mechanisms that can automatically verify a solution to a software engineering task.

Required Skills:
  • 3+ years of software engineering experience.
  • Strong expertise in building full-stack applications and deploying scalable, production-grade software using modern languages and tools.
  • Deep understanding of software architecture, design, development, debugging, and code quality/review assessment.
  • Excellent oral and written communication skills for clear, structured evaluation rationales.

Engagement Details:
  • Commitment: flexible engagement, minimum 10 hrs/week, up to 40 hrs/week (partial PST overlap required).
  • Type: Contractor (no medical/paid leave).
  • Duration: 1 month (starting next week; potential extensions based on performance and fit).
  • Location: Candidates must be based out of US, Canada or WEU countries (UK, Netherlands, Italy, Germany).

Note: As part of assessments you will go through an AI video interview.
