Hi I'm Abhik, Ashby's Co-Founder and VP of Engineering. We're looking for an ambitious full stack engineer who is laser focused on solving customer problems and making the right long term investments to solve them not only today but in our future features and products. What Ashby gives you in return is the best of both early and growth stage environments. The agency and no nonsense of a seed startup: you write product specs, make product and design decisions, and build in an almost no meeting culture. While also the product market fit and scale of a growth stage startup: tens of thousands of daily users who depend on your software and eagerly await your next feature. We have notable customers including Notion, Linear, Shopify, and Snowflake. About the Role And How We Work Our engineering culture strives to recreate the environments where we do our best work. I started my career building software for artists in the Visual Effects industry; success relied on my ability to be a product manager and designer. No daily stand ups, no t shirt sizing, no planning meetings. As a Product Engineer, you'll take ownership over a large portion of one of our products and own projects end to end (wearing hats traditionally worn by product and design). You'll research competitors, write product specs, make wireframes, and more. Designed and built automated interview scheduling that calculates possible times from interviewers and other constraints, presenting these times to the candidate for selection via our responsive web app. Built a generalized declarative filter architecture that allows users to create complex filters for any record with a consistent UI and compiles it to SQL in our backend. Specced, designed, and implemented a feature that lets users complete signing offers entirely within Ashby. What We're Building We're building talent acquisition software that removes blockers for recruiters. A recruiter needs to manually collect availability from candidates, identify qualified interviewers, perform "calendar tetris," schedule on the earliest date possible, and make last minute adjustments while considering interview load. We automate this workflow and provide insights into where they're failing. Qualifications & Fit Not afraid to tackle any part of the technology stack, whether frontend, backend, or infrastructure. Experience with projects that have product and technical ambiguity. Balance speed and quality; built high quality products on long timelines. Ambitious, always looking to improve skills and take on new challenges. Excellent collaborator and communicator, vetting decisions with stakeholders and working with other engineers. Seek to create leverage in work by automating or abstracting tasks. Not a Good Fit For You Need company driven process and structure to finish projects. Only want to do exciting work; prefer high level tasks over implementation. Get lost in details; prefer everything planned upfront. No prior ownership of projects; used to tasks assigned by leads. Want to mentor early career engineers; most team members are senior or above. Expect a tech lead primarily to project manage or do architecture reviews. Benefits Competitive salary and equity. 10 year exercise window for stock options. Unlimited PTO, encouraged to take time. Minimum 12 weeks fully paid parental leave. Generous equipment, software, and office furniture budget. $100 per month education budget; higher costs covered with manager approval. Top tier health insurance for US residents, 100% premiums covered; high quality supplemental insurance for other countries. Ashby provides equal employment opportunities (EEO) to all employees and applicants for employment without regard to race, color, religion, sex, national origin, age, disability, genetics, sexual orientation, gender identity, or gender expression. We are committed to a diverse and inclusive workforce and welcome people from all backgrounds, experiences, perspectives, and abilities. Compensation Range: £103K - £137K
