Inception creates the world’s fastest, most efficient AI models. Our Mercury model is the world’s fastest reasoning LLM and first commercially available diffusion LLM, delivering 5x greater speed and efficiency than today’s LLMs, with best-in-class quality.

We are the AI researchers and engineers behind such breakthrough AI technologies as diffusion models, flash attention, and DPO.

The Role

We seek experienced software engineers to build the applications, platforms, tooling, and infrastructure that make every team at Inception more productive. You'll own and drive customer use cases, build product features, development environments, and internal tools — that directly accelerate our ability to bring the latest AI technology to our customers. This role is ideal for engineers who care deeply about customer experience and developer velocity and want to work at a company where the software you build is a force multiplier on a world-class research and engineering org.

Key Responsibilities

Develop new product features to unlock new customer use cases
Create and maintain development environments, tooling, and workflows that improve developer velocity.
Build internal tools and dashboards for experiment tracking, resource management, and operational visibility.
Establish and promote engineering best practices around testing, code review, release management, and incident response.
Collaborate across research, ML infrastructure, and product teams to understand pain points and prioritize high-impact improvements.

Qualifications

BS/MS/PhD in Computer Science or a related field (or equivalent experience).
5+ years of experience in software engineering, application development, developer tooling, platform engineering, DevOps, or infrastructure roles.
Strong proficiency in Python; comfort with at least one systems language (Go, Rust, C++) is a plus.
Experience working with modern software development (CI/CD systems, GitHub Actions, Jenkins, BuildKite) and deployment automation.
Familiarity with Kubernetes, Docker, and container orchestration in production environments.
Experience with infrastructure as code and cloud platforms (AWS, Azure).
A strong empathy for customer experience and developer velocity — you care deeply about bringing AI to customers and about making other engineers' lives easier.

Preferred Skills

Experience developing AI/ML-powered product features that are loved by customers
Experience building and operating ML or GPU-intensive workloads (training clusters, inference pipelines, serving APIs, large artifact management).
Familiarity with monitoring and observability stacks.
Experience with testing strategies for ML systems (nondeterminism, regression testing, evaluation-driven validation).
Experience scaling developer tooling at a fast-growing startup or engineering organization.

About Us

Inception creates the world’s fastest, most efficient AI models. Today’s autoregressive LLMs generate tokens sequentially, which makes them painfully slow and expensive. Inception’s diffusion-based LLMs (dLLMs) generate answers in parallel. They are 5x faster and more efficient, while delivering best-in-class quality.

Inception was co-founded by Stanford professor Stefano Ermon, who co-invented such breakthrough AI technologies as diffusion models, flash attention, and DPO, UCLA professor Aditya Grover, who co-invented node2vec, decision transformers, and d1 reasoning, and Cornell professor and Afresh co-founder Volodymyr Kuleshov, who co-invented MDLM and Block Diffusion.

We pioneered the application of diffusion to language, with world’s first (and only) commercially available dLLM, Mercury. We are currently deploying our large-scale diffusion LLMs at Fortune 500 companies. Diffusion is the technology behind today’s image and video AI, and we’re making it the standard for LLMs as well.

Our team includes engineers from AWS, Google DeepMind, Meta AI, Microsoft, HashiCorp, and OpenAI. Based in Palo Alto, CA, we are backed by top-tier venture capitalists, including Menlo Ventures, Mayfield, M12 (Microsoft’s venture fund), Snowflake Ventures, Databricks, and Innovation Endeavors, and by tech luminaries such as Andrew Ng, Andrej Karpathy, and Eric Schmidt.

If you are talented, innovative, and ambitious, come help us invent the future of AI.

We are an equal opportunity employer and encourage candidates of all backgrounds to apply.
