What is a senior full stack software developer?

A Senior Full Stack Software Developer is an experienced professional who designs, develops, and maintains both the front-end and back-end components of web applications. They are proficient in multiple programming languages and frameworks, enabling them to work on the entire technology stack, from databases and servers to user interfaces. In addition to coding, they often lead projects, mentor junior developers, and help architect scalable solutions that meet business needs. Their role requires strong problem-solving skills, a deep understanding of software development best practices, and the ability to collaborate with cross-functional teams.

What are the key skills and qualifications needed to thrive as a senior full stack software developer?

A Senior Full Stack Software Developer needs advanced proficiency in both front-end and back-end programming languages, strong problem-solving skills, and several years of relevant software development experience. Familiarity with frameworks like React or Angular, back-end technologies such as Node.js or Django, and experience with cloud platforms, CI/CD tools, and version control systems like Git are typically required. Excellent communication, teamwork, and leadership abilities help developers collaborate effectively and mentor junior team members. These skills are crucial for designing robust, scalable applications and leading complex projects to successful completion.

What types of projects and technologies can a senior full stack software developer expect to work on, and how does the team typically collaborate?

As a Senior Full Stack Software Developer, you can expect to work on a diverse range of projects such as developing scalable web applications, integrating APIs, and optimizing system performance. The tech stack often includes front-end frameworks like React or Angular, back-end environments such as Node.js, Python, or Java, and databases like PostgreSQL or MongoDB. Collaboration is highly cross-functional—you’ll regularly coordinate with product managers, UX/UI designers, QA engineers, and other developers through agile methodologies, code reviews, and sprint planning sessions. This role offers opportunities to mentor junior developers, influence architectural decisions, and contribute to continuous process improvement.

What is the difference between Senior Full Stack Software Developer vs Software Engineer?

CredentialsBachelor's degree in CS or related field; experience in full stack developmentBachelor's degree in CS or related field; may have certifications in specific technologies
Work EnvironmentCollaborates across front-end and back-end teams, often in agile settingsDesigns, develops, and maintains software applications, often in teams or individually
Industry UsageCommon in tech companies, startups, and agencies requiring versatile development skillsWidely used across industries for software development roles

While both roles involve software development, a Senior Full Stack Software Developer specializes in both front-end and back-end technologies, often taking on leadership responsibilities. A Software Engineer may focus on specific areas of software design and implementation, with less emphasis on full stack expertise. The roles overlap in skills and industry usage, but the senior developer typically has broader responsibilities and experience in full stack development.

Job description

About Artificial Analysis

Artificial Analysis is the leading independent AI benchmarking company. We support labs, engineers and enterprises to understand AI capabilities and make critical decisions about their AI strategies. We are the go-to authority for understanding AI, from AI labs and enterprises to media, investors, and policymakers. Our benchmarks don't just measure the cutting edge of AI, they are actively shaping the frontier.

Our benchmarks and analysis are trusted by hundreds of thousands of users and are the go-to reference for leading AI labs including OpenAI, Google, Meta, NVIDIA and Anthropic, and major publications including the Wall Street Journal, Bloomberg, the Financial Times and The Economist.

We are a team of 35+, on track to triple by year end, backed by Nat Friedman (Github, Meta), Daniel Gross (SSI), Andrew Ng (Google Brain, DeepLearning.ai, Amazon), Adam D'Angelo (Quora, Poe, OpenAI), Clem Delangue (Hugging Face) and other industry leaders.

The Opportunity

We're looking for a Senior Full Stack Software Engineer to join our team and lead full stack development projects focusing on our website artificialanalysis.ai. You'll work closely with our founders to build core parts of the software stack for our early stage start-up.

The coming wave of AI scaling is going to change the world in ways we don't yet understand — and we're offering a front row seat.

What You’ll Do
  • Lead full-stack development and optimization of the Artificial Analysis website
  • Work with our TypeScript / Next.js stack (hosted on Vercel) to build and maintain website features, including using our PostgreSQL databases on Supabase
  • Design and implement user interfaces and data visualizations that distill complex AI benchmarking data into intuitive, interactive experiences for many thousands of daily users
  • Push forward our engineering practice more broadly, incorporating industry best practices into our DevOps, infrastructure management and CI/CD
  • Mentor and manage a small team of developers to drive a culture of engineering excellence
  • Embrace an AI-native workflow, using cutting-edge AI tools to generate leverage in a fast-changing industry
What We’re Looking For
  • 3+ years of professional software engineering experience, with a strong focus on modern front-end web development (JavaScript/TypeScript, React, Next.js, Node.js)
  • Knowledge of modern AI and experience using LLMs
  • Passion for AI and eagerness to work at the forefront of technological innovation
  • The ability to balance writing maintainable code and making sound architectural decisions with the need to ship features quickly
  • Strong problem‑solving skills and ability to distill complex concepts into actionable insights in the face of uncertainty
  • Excellent communication and collaboration skills
  • Proven ability to lead projects independently in a fast‑paced environment

Preferred but not essential:

  • Bachelor's or Master's in Computer Science, Engineering, or related field (e.g. Physics)
  • Experience with Python libraries for data analysis (e.g. pandas) and AI/ML frameworks (e.g. PyTorch)
  • Experience visualizing & presenting data
  • Creation of analytical reports
Why Artificial Analysis?
  • Shape how AI gets built: The leading AI labs track our benchmarks and use them to guide their development priorities. Your work will directly influence the direction of AI.
  • Become a world expert in AI: You will evaluate every major model, across every major capability, as they are released. Very few roles offer this breadth of exposure to frontier AI.
  • Work with the most important players in AI: You'll manage relationships with teams at the leading AI labs and major enterprises as a trusted, independent voice.
  • Join at a defining moment: We're 35+ people and fast growing, backed by some of the most connected investors in AI. The people who join now will shape the product, the team, and the strategy as we scale.
  • Competitive compensation including equity
  • Our team is split across San Francisco, Sydney, and Melbourne
