Open roles
London (On-site/Hybrid)
The opportunity
As Founding HW-SW Codesign Engineer, you’ll work where software meets silicon. You’ll own the journey from application to the hardware that delivers it, and drive the development of our autonomous chip design platform. You’ll start from the earliest stages of the project and influence the technical architecture of our product. There’s no playbook: you determine the design principles and approaches, and you build it.
What you’ll do
- Own multiple applications end to end, from performance estimation to SoC architecture
- Software tools for fast performance simulations in low level programming language (C++/Rust)
- Think across hardware and software boundary to identify performance bottlenecks
- Convert ambiguous technical problems into systems and communicate the approach to a wider audience
- Shape the direction of the work alongside the rest of the founding team on product, technology and hiring
What you bring
- Deep understanding on both sides of the hardware/software stack, and the instinct to work on low-level performance optimizations
- Experience delivering high-quality production software and ability to drive agents to write most of the code
- A first-principles mindset: comfortable taking on problems no one has solved before
- The confidence to talk to multiple stakeholders and turn an ambiguous problem into a concrete plan
- A startup mindset: high ownership, comfortable with ambiguity, able to move fast
The opportunity
As Founding Software Architect, you’ll own the software foundation of Tattvam. You’ll decide how our systems fit together and how to support an interdisciplinary software system, where AI writes most of the code, across the hardware and software stack. You’ll start from the earliest stages of the project and influence the technical architecture of our product, making the decisions everything else is built on. No prior chip design experience is required.
What you’ll do
- Own the software architecture of our highly scalable, high performant chip design systems
- Define and drive methodologies for high-quality, reliable and verifiable software in a world where AI writes most of the code
- Build performance optimized custom tools and systems in low level language (C++/Rust)
- Shape the direction of the work alongside the rest of the founding team on product, technology and hiring
What you bring
- A record of designing and shipping complex software systems
- Low-level depth: you understand what happens beneath the abstractions, and you’re curious about hardware
- A first-principles mindset: given a new problem, you work out the right way to build it
- Hands-on experience building with AI, and strong opinions on how to do it well
- A startup mindset: high ownership, comfortable with ambiguity, able to move fast
The opportunity
As Founding Chip Architect, you’ll lead architecture and the design process across multiple chips. You’ll also shape how our autonomous system designs chips, and drive the end-to-end process for delivering multiple chips. You’ll start from the earliest stages of the project and influence the technical architecture of our product.
What you’ll do
- Define and implement SoC architecture across multiple chips and drive the company’s roadmap
- Drive the specs of our autonomous chip design system working at the intersection of architecture, design, verification, physical design, custom tools and AI workflows
- Estimate area, timing, performance and power at the earliest stages to inform architecture trade-offs
- Define clear HW-SW boundary for multiple chips supporting diverse workloads
- Shape the direction of the company alongside the rest of the founding team on product, technology and hiring
What you bring
- Deep understanding of chip architecture across multiple varieties of chips, and a track record of leading real chips through to tape-out
- A strong experience of the entire design flow and opinions on autonomous design flow
- Sharp judgement on the trade-offs that matter, and the clarity to explain them to anyone
- An appetite for AI: you’re excited to put your expertise into autonomous systems and drive next generation of chips
- A startup mindset: high ownership, comfortable with ambiguity, happy to be hands-on
The opportunity
As Founding AI Engineer, you’ll own the intelligence at the core of Tattvam. You’ll build AI systems to solve problems that haven’t been solved before, in a field where getting it right ends in real silicon. You’ll start from the earliest stages of the project and influence the technical architecture of our product, at the frontier of what AI can do. No prior chip design experience is required.
What you’ll do
- Build RL environments for self-improvement across various parts of chip design stack
- Design and build the AI systems that make decisions autonomously across the chip design stack
- System level optimizations to solve more tasks efficiently within a given time and compute budgets
- Make our systems faster, smarter and more reliable, and build custom intelligence where general-purpose models aren’t enough
- Shape the direction of the work alongside the rest of the founding team – framing the problem, proposing solutions, and designing the experiments to test them
What you bring
- Deep understanding of how to build custom AI systems for hard, frontier problems (e.g. AI for mathematics, AI for biology)
- A first-principles mindset: given an entirely new problem, you can understand its structure and build an AI system to solve it
- Strong engineering skills to build multidisciplinary systems and curiosity about hardware
- A startup mindset: high ownership, comfortable with ambiguity, able to move fast
The opportunity
As Founding EDA Engineer, you’ll help reinvent the chip design process and tools. You’ll be rethinking assumptions in existing tools and flows on a daily basis, and building what comes next, so that design can be done autonomously. You’ll start from the earliest stages of the project and influence the technical architecture of our product, giving shape to something that hasn’t existed before.
What you’ll do
- Own EDA software stack of the company across multiple stages of chip design from RTL to GDS
- Build custom tools from first principles in low-level programming language (C++/Rust)
- Push the frontier of reliable, high quality and maintainable code where AI writes most of the code autonomously
- Propose novel EDA architectures for autonomous chip design and drive the experiments
- Shape the company’s direction alongside the rest of the founding team across product, technology and hiring
What you bring
- Internals-level understanding of how EDA tools are built (algorithms, engines, data models)
- Strong quantitative background to propose innovative algorithms for chip design
- Strong software fundamentals with experience in low-level programming language (C++/Rust)
- A first-principles mindset: comfortable taking on problems no one has solved before
- A startup mindset: high ownership, comfortable with ambiguity, able to prototype fast

About Tattvam AI
Tattvam AI is a frontier lab building autonomous systems for end-to-end chip design, backed by Tier-1 investors across Europe and North America.
Efficient chips set the limits of what computing can do. Yet building one still takes hundreds of engineers and years of work, so most applications end up running on hardware that was never designed for them. We’re solving open problems across software, hardware, AI and systems to build towards autonomous silicon: from idea to fully functional chip, so that every application can have a chip built for it.
What we offer
- Opportunity to push the frontier of compute, as one of the founding hires
- Ownership of problems no one has solved yet
- A competitive base salary
- A meaningful equity stake in a high-growth, early-stage startup
