🚀 About Us

We’re Bolt.new by StackBlitz!

We're the team behind WebContainers, the groundbreaking technology that made it possible to run Node.js right in your browser. No installs, no setup, just instant dev environments. That innovation kickstarted our journey in 2019 and powers the blazing-fast online IDE used by over a million developers every month.

But we didn't stop there.

We took everything we learned from building WebContainers and used it to create Bolt.new. The fastest way to go from idea to production without writing traditional code. Think of it as the Canva or Figma for full-stack applications: a next-gen, AI-powered builder that lets you create, edit, and deploy web and mobile apps instantly, right in your browser.

WebContainers make it possible. Bolt.new brings it to life. Together, they reimagine what it means to build software lowering the barrier to entry, speeding up workflows, and unlocking creativity for the next generation of builders.

We're a globally distributed, fully remote team of passionate engineers, designers, and creatives building the future of software development. If you love shipping fast, solving real problems, and pushing the boundaries of what's possible we'd love to meet you.

✨ About This Opportunity

You'll lead the technical direction of the AI agents that turn natural language into production-ready applications. This means shaping how we work with LLMs to solve our hardest problems: maintaining context across large codebases, orchestrating multi-step workflows that feel intuitive, and handling everything from simple UI tweaks to complex architectural decisions.

This isn't API integration work. You'll define the patterns and systems that govern how AI reasons about and generates full-stack applications, driving initiatives that span multiple teams and influence our broader AI strategy. Your work shapes the experience of millions of users building real products with Bolt every day.

🛠️ How You'll Contribute 

  • Define AI Agent Architecture: Lead the design and evolution of our AI agent systems, establishing patterns, frameworks, and standards that teams across the organization adopt. Own the technical vision for how agents manage context, orchestrate workflows, and scale to handle increasingly complex user needs.
  • Drive Multi-Provider Strategy: Shape our approach to leveraging models from providers such as OpenAI (GPT series), Anthropic (Claude), and Google (Gemini). Establish evaluation frameworks and selection criteria that teams use to choose the right model for a given task. Build relationships with provider teams to influence roadmaps and beta-test new capabilities.
  • Architect Tool Use and Workflow Systems: Design the foundational systems that enable AI agents to call external tools and APIs safely and effectively. Define the abstractions and interfaces that allow the agent to perform actions like web searches, database queries, and domain-specific operations. Evaluate and recommend frameworks such as Vercel's AI SDK, LangGraph, and others, establishing best practices for the organization.
  • Cross-Team Leadership: Partner with teams across engineering, product, and design to align AI initiatives with business objectives. Influence roadmaps, resolve technical disagreements, and ensure AI-driven features are architected for long-term maintainability and performance. Mentor senior and mid-level engineers, raising the bar for AI engineering practices across the organization.
  • Establish Data and Evaluation Standards: Define the methodology for collecting, curating, and analyzing datasets from agent responses and multi-turn conversations. Build and steward the evaluation harness, ensuring evals directly support business objectives and KPIs. Turn insights from conversation patterns, failure modes, and success signals into systematic improvements.
  • Drive Research and Innovation: Stay at the forefront of NLP and LLM research, identifying and championing novel techniques that provide competitive advantage. Lead experimentation with new prompting strategies, context handling methods, and fine-tuning opportunities. Represent StackBlitz in external forums, conferences, and community discussions where appropriate.

đź’ˇ Qualifications

  • TypeScript: Familiarity with TypeScript is important. Our entire stack is built on it. Willingness to work in TS daily is key.
  • Deep LLM Experience: Extensive hands-on experience working with Large Language Models (LLMs), with a nuanced understanding of their capabilities, limitations, and emergent behaviors. Proven track record of building and scaling production AI systems.
  • Prompt Engineering: Deep expertise in prompt engineering with the ability to establish best practices and mentor others. Skilled at crafting, refining, and optimizing prompts across different tasks, models, and use cases.
  • Software Engineering Excellence: Strong software engineering fundamentals with experience designing systems that scale. Able to make architectural decisions that balance immediate needs with long-term maintainability.
  • Strategic Execution: Ability to take ambiguous, high-scope problems and drive them to completion with minimal oversight. Comfortable influencing direction across teams and navigating complex technical and organizational challenges.
  • Systems Thinking: Ability to identify process, communication, and technical debt across the organization and propose solutions that accelerate velocity for multiple teams.
  • Data-Driven Leadership: Experienced in establishing data collection and analysis practices. Able to build evaluation frameworks, identify patterns in agent behavior, and translate findings into organizational improvements.
  • Strong verbal and written English communication skills are required, as this role involves frequent collaboration with team members, stakeholders, customers, and potentially external audiences where English is the primary working language.

🎯 Bonus Points 

  • DSPy Framework: Familiarity with DSPy (Declarative Self-improving Python) for building modular AI systems and optimizing prompts programmatically.
  • Machine Learning Background: Understanding of ML fundamentals and experience with model evaluation metrics.
  • Open Source Contributions: Experience contributing to or maintaining open-source AI/ML projects.
  • Research Background: Experience reading and implementing techniques from AI/ML research papers.
  • $ Experience speaking at conferences, publishing technical content, or representing an organization in industry forums.

Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
