Additional Information
Interview Process: Step 1 – Short survey. After reviewing resumes, Hestus sends a short online questionnaire (~15 minutes) to candidates who meet the basic requirements., Step 2 – Initial call. A 30–45 minute video call over Google Meet to learn more about your background, interests, and what you’re looking for, and to share more about Hestus, the role, and how they work., Step 3 – Coding challenge. A practical take-home coding exercise (target ≤ 8 hours) focused on Python, backend fundamentals, and problem-solving., Step 4 – Technical interviews. A series of deeper technical interviews with the CEO, CTO, and engineering team. Candidates in the Bay Area are invited to the San Mateo office; others join via Google Meet. These sessions cover system design, backend implementation, and collaborating in a startup environment., Step 5 – Offer & closing. For candidates who pass the loop, Hestus discusses compensation details, equity, and start date, and moves quickly to a formal offer.
Day to day: You’ll spend most of your days building and shipping production features that make Hestus’ AI-powered CAD feel fast, reliable, and delightful for hardware engineers. Some days you’ll be deep in Python and backend APIs, designing data models, writing queries, and improving performance; other days you’ll be pairing with the founders to scope new workflows, refine UX, or debug tricky edge cases in how customers actually design parts. You’ll touch everything from backend services (Flask/SQL) to light ML integrations, and you’ll ship small, frequent updates with tight feedback loops from both the team and real users.
Team: You’ll report directly to the founder and work closely with a small, senior team of engineers and researchers. The environment is flat and hands-on — everyone ships code, reviews each other’s work, and contributes to product direction. You’ll have a front-row seat to how an AI CAD product is built from the ground up, and your code will quickly make its way into the hands of real customers.
Growth: Take ownership of key services and CAD-related workflows end-to-end., Grow into a Staff / Principal engineer or early team lead as the company scales., Mentor future hires and help shape Hestus’ engineering culture, processes, and best practices.
Ideal Candidate Profile: Product-minded builder who loves turning ideas into reliable, maintainable code. You’re fluent in Python, comfortable with backend frameworks like Flask or Django, and you care about performance, correctness, and clean abstractions. You’re curious about how ML can power better tools, even if you’re not an ML expert yet, and you’re excited to work closely with founders and customers to ship the right thing — not just more lines of code. Most of all, you like small teams, high ownership, and the idea of spending the next few years working on a single, hard problem: making AI-powered CAD the new standard for hardware design.
