About Circuit Mind:
Electronic circuit boards are at the core of current and future inventions - space travel, medical robotics, autonomous transportation, augmented reality, bio-engineering. Yet today designing an electronic circuit board is an extremely manual, long and tedious process. At Circuit Mind we believe that this is wrong and we are on a mission to fix it, triggering the future of hardware design.

We are creating an entirely new software engine for circuit boards, that takes as inputs the requirements of a circuit board and automatically outputs a complete design, ready for manufacture.

As a Lead Software Engineer, you will create simple and elegant solutions to difficult technical problems that the world has not solved before. You will work in close collaboration with a highly-functioning team of software, electronics, algorithm engineers and product managers.

Benefits:

• Collaboration with a friendly world-class team.
• Above market rate salary and meaningful equity.
• 25 days of annual holidays plus bank holidays.
• Flexible working hours with two days a week in the office.
• 5 weeks per year to work wherever you want in the world.
• London Bridge office.
• Extended parental leave.
• Learning and development budget to support your professional development.
• Yearly retreat.
• Access to Circuit Minds cutting edge EDA platform.

Interview Process:

• Screening Interview, 20-30 min with Operations Manager.
• Technical Interview, 120 min with Rob (Principal Full-stack Engineer) and Niall (Lead Software Engineer):
• Hour 1: Review a pull request for a miniature version of our main Python product.
• Hour 2: Implement a new feature in a similar repository.
• Final Interview, 120 min with Basilio (CTO and Co-founder) and Rob (Principal Full-stack Engineer): Deep dive into your experience with behavioral and experience-based questions.
• Reference Checks: Two references that you provide will be contacted for feedback.
• Offer: Based on successful completion of all stages.
