To automate hardware design for the benefit of science and the welfare of humanity.
Role
Who you are
- Extensive full stack experience with TypeScript/React and Python, with a track record of architectural decisions at scale
- Strong algorithmic problem-solving skills with understanding of complexity analysis, graph/tree data structures, and computational efficiency
- Ability to drive technical direction and follow through on architectural decisions across the stack
- Experience identifying technical debt, evaluating tradeoffs, and building consensus around solutions
- Self-directed work style with strong product sense and ability to unblock yourself and others
- Experience gathering requirements from stakeholders and translating them into technical solutions and system designs
- Track record of owning large, complex features from planning through production
- Ability to mentor and raise technical standards across a team through code reviews and establishing best practices
- Comfortable working with ambiguity in a startup environment
- You're a veteran software engineer who's worked across multiple environments and knows that early-stage startups offer the best combination of impact and interesting problems to solve
- You have a nose for bottlenecks—you spot where things are getting stuck and jump in to help get features across the finish line. You're naturally curious about architecture, always tinkering to find proactive improvements that can ship quickly. You move fluidly across the codebase and the team, bringing speed without sacrificing quality
- Your algorithmic problem-solving is strong and you don't shy away from maths and logic. You're comfortable reasoning about complexity at various levels of abstraction, working with graph and tree structures, and finding elegant solutions to hard computational problems
- You're responsible with your craft. You plan, you test, you own large features end-to-end. You think about staging, reliability, and production-readiness from the start, not as an afterthought
- At a principal level, you're also a multiplier. You make the engineers around you better through thoughtful code reviews, clear technical communication, and by establishing patterns that scale beyond your own code. You know when to dive deep into implementation and when to step back and focus on architecture and direction
- You thrive when given ownership of a problem space. You're the person who asks "why are we building this?" before diving into "how should we build it?" You don't need your hand held, but you're not afraid to raise your hand when you need context or when you spot a problem with the plan
Desirable
- Experience with graphics/visualization libraries (PixiJS, Three.js, WebGL)
- Background in developer tools or technical products
- MongoDB and PostgreSQL experience, or other databases
- Auth/identity management systems (WorkOS, Auth0, etc.)
- Polyglot programming experience—comfortable across multiple languages and paradigms
- Interest in hardware, electronics, or CAD tools
What the job involves
- We're looking for a principal engineer who can drive technical direction for significant product areas and own them end-to-end
- You'll work across our stack—from user management systems to our core design application—making architectural decisions that shape how electrical engineers interact with our product for years to come
- As a principal engineer, you'll be expected to identify technical debt, propose solutions, and drive consensus around the right path forward
- Your first major project will be reworking our user and license management system, which you'll architect and largely implement while coordinating with stakeholders across the company
- As you ramp up and build context on our domain, you'll transition to working on critical core runtime components that power our circuit design engine
- Beyond your individual contributions, you'll raise the bar for engineering across the team—through code reviews, technical mentorship, and establishing patterns that others can follow
- TypeScript/React frontend
- Python application server
- Database backend currently in PostgreSQL
- Integration with modern auth solutions (WorkOS or similar)
- Graphical User Interface Application
- Electron based React/TypeScript application
- Custom input handling and rendering (not traditional HTML elements)
- Advanced visualization using PixiJS, with potential migration to WebGL/Three.js
- Complex CSS/styling for polished UI/UX
- Application Runtime & Architecture
- Algorithm-heavy runtime with complex computational geometry problems
- User-facing Python API for programmatic circuit board design
- Sophisticated architecture driving the application life cycle
- Opportunity to rearchitect core systems to leverage parallel computing and modern hardware capabilities
- Deep technical challenges requiring strong CS fundamentals and architectural vision
Our take
When designing circuit boards, engineers use graphical tools. However, modern circuit boards are so complex that it is almost impossible to design at the level of detail required without encountering errors. Jitx introduces a solution to this problem by bringing software to hardware design, allowing electrical engineers to design in code and then compile it into a board layout with the help of AI. By automating testing and review processes within its platform, Jitx allows a degree of precision and ease of deployment unmatched by manual design processes.
The global market for circuit board design is estimated at over $9 billion, and Jitx is not alone in attempting to disrupt this space, with companies including Celus, Circuitmind and Zuken, among others, attempting to use AI to automate circuit design. But Jitx stands apart by using code rather than a graphical or descriptive interface to streamline this process, and this extra level of control and ability to share layouts over, for instance, GitHub, may give it a strong niche within the sector.
Jitx closed a Series A funding round in 2022, led by Sequoia Capital. It is moving to develop its platform, adding more automation features to further speed up circuit board design. Having emerged from stealth only recently, it is also hiring, hoping to expand its team to take advantage of its rapidly growing client base.
