We’re looking for a curious, rigorous, problem‑hungry platform engineer (who codes!) to carry the ball as we bring Ashby to the big leagues. Ashby builds software that lets talent teams build an efficient, delightful, respectful hiring process. Similarly, you’re an engineer who wants to build a “paved road” that excellent engineering teams can safely take to the moon and back.

We have notable customers like Notion, Linear, Shopify, and Snowflake. Our growth and retention metrics are best‑in‑class among our peers: we have tens of millions in ARR, growing >100% year over year, over 2500 customers, very low churn, and many years of runway. We’ll share more details once we meet, but you now probably have a good idea as to why we're hiring for this role.

We’ve listed this role twice: as a Platform Engineer and Site Reliability Engineer – our team does both, and we are open to candidates who lean towards one or the other.

Hi I’m Colin, Head of EMEA Engineering. I’ve spent a number of years leading engineering teams in startups, and that has always included being close to infrastructure teams – no matter what name they’ve worn (SRE, infrastructure, platform, etc). I’ve got my hands dirty building the initial infrastructure for startups and know the value a talented infrastructure engineer brings. The rigour, the discipline, the peace and quiet when everything just hums along.

Our infrastructure is in a good place for now. Nothing is static. Ashby continues to grow rapidly, putting strain on our existing infrastructure. We’re always looking to give our customers more powerful hiring software, and building new product features often requires new pieces of infrastructure.

Having herded plenty of snowflake servers in the past, I’ve learned there’s a better way. I (and Ashby) place a lot of value on infrastructure‑as‑code. As a Platform Engineer at Ashby, you’ll dive into scaling problems, add new capabilities to our platform, and think about how our entire team interacts with infrastructure.

We’re at an inflection point where our ability to scale and deliver a seamless experience has a make‑or‑break impact – we have some of the fastest growing companies using our platform every day to hire hundreds of people per month. We need someone like you to make good decisions, debug thorny issues, and build us a future‑proof platform that can withstand this scale.

• Optimize our homegrown ultra‑dynamic recruiting DSL‑to‑SQL compiler, and create tools to help developers do so
• Create automated guardrails for the security and privacy of our customer data
• Help our developers ship features fast through canary deploys, gradual rollouts and feature flags, while keeping complexity manageable and reducing downtime
• Work with the business and engineering team to define SLOs and implement the corresponding SLIs
• Ensure all communication with external services supports retries and circuit‑breakers
• Implement the infrastructure to support an event‑driven architecture and data warehouse

• Strong coding skills and a passion for building platform‑level software
• Experience with infrastructure‑as‑code, cloud (AWS), containers, and CI/CD pipelines
• Comfort with SQL, monitoring, alerting, and performance tuning
• Hands‑on experience with SRE practices such as SLOs, SLIs, and chaos engineering
• Excellent communication skills and a proactive, ownership‑driven mindset
• Commitment to security, privacy, and reliable system design

• You never stop obsessing over problems until they make sense and have elegant solutions
• You don’t take shortcuts and you speak up for the future user, edge cases, and doomsday design
• You care about the team you work with and want to work with people who make you better
• You have built infrastructure at a later stage than Ashby is now, dealing with millions of data points and automating provisioning, monitoring and release processes
• You’re a Swiss army knife – ready to tackle infrastructure updates, security enforcements, database optimization, Kubernetes debugging, and more

• You don’t want to make your own decisions on the best paved road and expect a manager to make the final calls
• You hate SQL
• You don’t want to code
• Your primary mode of communicating best practices is live meetings – we have a very async culture and rely on written communication and code
• You’ve never delivered a project on your own, without someone prodding you for updates

TypeScript (frontend & backend), Node.js, React, Apollo GraphQL, Postgres, Redis, Datadog, Sentry, AWS.

• Competitive salary and equity
• 10‑year exercise window for stock options
• Unlimited PTO
• Minimum 12 weeks of fully paid parental leave
• Generous equipment, software, and office furniture budget
• $100/month education budget (conference coverage with manager approval)
• Top‑tier health insurance (US) or high‑quality supplemental health insurance (other countries)
