Job description
About Us:

We are a funded, early-stage AI startup operating in stealth mode.
We are building Solvin, the world’s first fully autonomous AI teammate that independently fixes bugs end-to-end, freeing developers to focus on features and innovation. Unlike existing coding assistants that require constant developer supervision, Solvin operates as an autonomous virtual engineering team member. Powered by a novel multi-agent operating system, Solvin works in the background to transparently handle the entire bug lifecycle. We have designed our platform from the ground up for enterprise environments, with a deep focus on security, observability, and fine-grained control.

The Role:

As a Founding Engineer, you will be a cornerstone of our technical team. You will have a pivotal role in designing, building, and deploying the foundational elements of our product. We're seeking a passionate and experienced engineer who is excited by the challenge of building a product from its initial concept to a production-ready MVP and beyond. You will work in a dynamic, fast-paced environment where your contributions will be visible and impactful from day one. This role requires a blend of strong technical expertise, a product-oriented mindset, and the ability to thrive in the ambiguity of an early-stage startup.

What You'll Do:
  • Take ownership of significant parts of our system, architecting and building our core product from the ground up.

  • Write clean, high-performance, and scalable code, primarily in Python.

  • Collaborate closely with the founders to define and iterate on the product roadmap and technical strategy.

  • Design, build, and maintain the infrastructure for our AI and machine learning models.

  • Establish and champion best practices for software development, including testing, CI/CD, and code reviews.

  • Contribute to all phases of the product development lifecycle, from ideation and design to implementation and launch.

  • Help shape our engineering culture and, as we grow, mentor and guide future team members.

What We're Looking For (Qualifications):
  • A seasoned engineer with 7+ years of software development experience.

  • At least 3 years of professional experience in Python development.

  • A minimum of 1 year of hands-on experience building generative AI technologies and agentic systems utilizing LLMs and frameworks like LangChain or LlamaIndex.

  • Proven expertise in backend development and experience shipping and maintaining production systems.

  • A self-starter with the ability to work independently and navigate the challenges of a fast-paced startup environment.

Bonus Points (Advantageous Skills):
  • A strong background in cloud computing (AWS, GCP, or Azure) and Kubernetes.

  • Proficiency in other programming languages such as Java, C++, or TypeScript.

  • Familiarity with Python build systems and packaging.

  • A Bachelor's degree in Computer Science. A Master's degree or PhD is a strong plus.

Why Join Us?
  • Foundational Impact: You will be more than just an early employee; you'll be a true partner in building our company and culture.

  • Significant Equity: We offer a generous equity stake, ensuring that you share in the success you help create.

  • Cutting-Edge Technology: Work at the forefront of AI and solve challenging problems with a real-world impact.

  • Direct Influence: Your ideas and decisions will directly shape the future of our product and company.
