Fullstory provides privacy-preserving session replay and analytics for websites and mobile apps. Our session replays are nothing short of magical, and the combination with analytics creates eye-opening insights.
We have several engineering roles open:
* Senior Software Engineer, iOS - $176,000 to $207,500 - https://www.fullstory.com/careers/jobs/ab3f8ecb-ee1f-4431-a0...
* Senior Software Engineer, Application Experience - $160,000 to $190,000 - https://www.fullstory.com/careers/jobs/1a014b19-d805-4547-9a...
* Senior Manager, Engineering - $205,000 to $255,000 - https://www.fullstory.com/careers/jobs/bce3fcba-6b80-43fd-b7...
...and a few roles in other categories, see https://www.fullstory.com/careers/ for the full list and some general info.
Tech stack includes Typescript & React for the front-end; Go (Golang) running on Google Cloud (GCP) w/ Kubernetes (K8s/GKE), BigTable, BigQuery, Solr, and more for the back-end; Java, Objective-C, and Rust for mobile; and smaller amounts of other languages including Swift, Kotlin, Dart, Python, and Ruby where they make sense.
Note that for the iOS role, we're not building apps. It's about taking things apart, seeing what makes them tick, and figuring out how to extract the data we need without negatively impacting the app experience. (Or using any private APIs!) It's part reverse engineering, part systems programming, and part library development.
In addition to the listed pay ranges, you can expect regular raises & bonuses, equity, and benefits including: health insurance, 401k matching (Vanguard), annual learning stipend, unlimited PTO, and more. I take about 5 weeks vacation a year, in addition to ~3 weeks worth of company holidays (federal holidays + the week of Christmas to New Years.)
You also get a 5-week sabbatical after 5 years of employment - I just took mine at the end of last year, and it was fantastic.
To apply, please submit your info on the website. If you have questions, feel free to reply here or email nathan@[company website].com.

At https://Sneos.com, I've built a platform that allows users to write once and compare outputs from multiple AI models like ChatGPT, Claude, and Gemini side-by-side. This helps users understand the unique strengths and perspectives of different AI systems without the hassle of copying/pasting between services. Current Needs:
Growth Hacker (part-time/contract): Looking for a creative, data-driven growth specialist to help me scale the user base and optimize conversion from free to premium tiers. You should have experience growing B2C SaaS products and be comfortable implementing and analyzing marketing experiments quickly.
iOS/Android Developer (part-time/contract): While not an immediate priority, I'm interested in creating mobile versions of my web app. As the premium user base grows, I'd allocate more resources to mobile development. I'm open to sponsoring an open-source implementation initially, with potential for a more formal arrangement as user numbers increase.
Tech Stack:
Flexible (Objective C, Swift, Java, .NET, etc.)
What I Offer:
Flexible remote work Opportunity to shape a product in the rapidly evolving AI space Competitive compensation aligned with company growth
If you're excited about making AI tools more accessible and effective for everyday users, please reach out with your relevant experience and a brief note on why you're interested in working with Sneos.

Felt Clinic is building the first embedded care SDK for health apps. Our mission is to make access to a doctor simple and secure inside any mobile application. We want teams to stop worrying about provider contracting and focus on building awesome experiences.
We're looking for a Senior Full Stack Engineer to help us scale our platform. You’ll be developing powerful SDKs and APIs, integrating real-time communication tools, and shaping next-generation digital health experiences.
Tech Stack:
- Mobile: SwiftUI (iOS), Kotlin (Android), Ionic
- Web: Next.js, Turborepo, TypeScript
- Communication: WebRTC
What sets exceptional candidates apart:
- Hands-on experience working on mobile platforms (Swift/Kotlin)
- Solid experience with Next.js and RSC
- A passion for transforming healthcare experiences
- Deep expertise in full-stack product development
Felt has three customers actively using our SDKs and anticipating approximately $10m ARR by late 2026. We’re backed by leading investors including 1984, Scrum Ventures, and Tau Ventures. Join us as we scale to build next-gen HealthKit on steroids.
Apply by contacting us directly at sid+yc (at) feltclinic.com.
MixRank processes petabytes of data every month from web crawling. We have hundreds of customers using our data products including Google, Amazon, Facebook, Intel, and Adobe, across industries including Finance, Recruiting, Sales, Marketing, and Security.
We’re a fully-remote company with a global footprint in over 20 countries. We're growing, profitable, employee-owned, no dependence on outside funding. Applicants from all geographies and backgrounds are welcome.
We are looking for passionate individuals for whom programming is not just a job but it’s something they love to do. We're obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team.
Our code base is very friendly to new contributors. You'll have a fully-functional development environment within hours (fully automated) and be pushing commits on your first day. Deployments to production happen multiple times per day and finish in less than 2 minutes. Effectively all of our codebase is written in Python, Rust, SQL, Javascript/TypeScript, and Nix. The core technologies you'll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.
We operate at a larger scale than typical startups. We operate two datacenters with high performance servers we've built that are capable of dealing with the volumes of data we process. We've implemented our own distributed file system. We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual.
We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.
