REMOTE (US-West preferred) OR on-site (DC, SF or London)

We are looking for a passionate and experienced Distributed Systems wizard. If some of the following items excite you, then you’d probably enjoy working with us.

  * Systems Dependability: fault tolerance and high availability
  * Foundational D.S. problems (leader election, fault detection, consensus, atomic broadcast, etc.
  * Testing and benchmarking techniques (chaos Engineering, fault injection, fuzzing, property-based testing, Jepsen, ...)
  * Replication techniques and protocols
  * Debuggers and debugging techniques
  * Distributed Databases & Consistency Models
  * Durable Message Queues & Workflows
  * Formal verification
If you have (at least a few years of) experience in at least 3 of the items above, you’re a good fit.

About the job: you’ll get your hands dirty on a number of distributed systems of various shapes and sizes. Some traveling required (conferences, customers visits, and HQ visits if you are remote).

About us: Well established startup. One-of-a-kind product, used by a growing number of well-known companies. Great team chock full of impressive, passionate, fun people.

Send your CV to flybys.verb.4e@icloud.com

Please include:

  * A brief comment of why you think we're a good match
  * Which of the areas above you are experienced in (prepare to be grilled on them!)
  * The string ‘mantis shrimp’ to make it past our spam filter.

SmarterDx | 150-250k+ + equity + benefits | Remote (US only) | Multiple roles | https://smarterdx.com/careers

We build clinical AI that empowers hospitals to analyze the complete record of every patient to fully capture the value of care delivered. Founded by physicians in 2020, our proprietary AI platform understands the nuances of clinical reasoning, enabling hospitals to accurately reflect every patient visit for fair reimbursement. By doing so, hospitals can recover millions in earned revenue, enhance care outcome and quality metrics, and optimize healthcare operations.

The current team is very high functioning (MD + data scientist combos, former ASF board member, Google and Amazon engineers, Stanford LLM researchers, etc.) and initially scaled the company to $1MM+ in contracted revenue without raising capital.

SmarterDx recently became part of Smarter Technologies as part of a $1.1B deal by New Mountain Capital, a leading growth-oriented investment firm. We have been backed by top investors including Floodgate (Lyft, Twitch, Twitter), Transformation Capital, and Bessemer for a total of $71M, including our $50M Series B, and are experiencing an incredible growth trajectory customer and revenue wise with no signs of slowing down with 150% YoY headcount growth! This time last year, we were at ~110 employees, and are above 280 as of today!

We are looking for: Security Engineering Manager - Staff and Senior SWEs, Full Stack and Backend focused - Staff ML Engineers - Data Science Managers - Staff Data Scientists - Senior Data Analysts - Senior Product Managers - More!

We have PMF, and it's time to scale! For more and to apply, see https://smarterdx.com/careers

ReciPal (https://www.recipal.com) | Founding Rails/Full Stack Software Engineer | REMOTE | Full-Time

We aren't actually hiring anyone immediately, but we've hired a handful of great engineers from HN and inevitably will need to hire again. We've found having those conversations and keeping in touch is much better than going through the process from scratch each time, as it fast tracks the process a great deal when the time comes. So reach out if you think you're a good fit.

ReciPal is a profitable, growing, bootstrapped, and (have always been a) fully remote company (based in New York) with 6 full-time employees. We make simple software for food businesses - nutrition analysis and labeling, costing, and inventory management. We've been around for almost 15 years now!

You'd be working directly with me, solo founder, our senior engineers, and marketing and support colleagues, and hopefully take on a growing role over time to treat the business like your own. It's a very low key work environment, but independent and plenty of responsibility and ownership for the right person.

Stack includes Rails 8, JavaScript, Postgres, Heroku.

Raremarq | Founding Engineer | Full-time | Fully Remote | $150K + founding-engineer equity

Raremarq (raremarq.com) is building the Stripe for Auctions — a no-code/low-code platform that lets brands, creators, and businesses embed auctions and dynamic pricing directly into their stores. Our auction engine already powers real-time bidding, payments, and fulfillment for tens of thousands of users, helping sellers earn millions. We’re backed by notable investors including LAUNCH (Jason Calacanis) and Blockchain Founders Capital with more to be announced soon. Our founding team is ex-Google and ex-Amazon, and we’ve been founding employees at multiple startups.

We’re hiring a Founding Engineer to join as one of our first hires. You’ll own the evolution of our core API — taking it from an internal product to a public developer platform powering auctions, bidding, payments, and notifications anywhere on the internet. The stack includes TypeScript (Hono, SvelteKit), Convex, Stripe/PayPal, and modern developer tooling.

The ideal candidate has 4+ years of software engineering experience, strong API design skills, and familiarity with payments, databases, and full-stack frameworks. This person should be eager to take the vision of “Stripe for Auctions” and make it their own with the goal of building a best-in-class, developer-facing platform that can help millions of businesses. Bonus points for experience building developer platforms and/or early-stage startup experience.

We offer competitive salary, founding engineer-level equity, full healthcare, unlimited PTO, and a remote-first culture. Interested? Apply here: https://forms.gle/KnwFTiTigyQnXrzy9
