Fullstory | Atlanta or Remote (US) | https://www.fullstory.com/

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.

Anvil (https://anvil.works) | Senior Developer | Cambridge, UK | ONSITE, VISA | Full-time/part-time/flexible

We make an open-source web framework, an online code editor, a GUI builder, and a PaaS hosting platform. Together, you can build and host a full-stack web application - and all you need is a little Python. (Yes, even the client-side code - we compile Python to JS and provide a GUI framework!)

We’re looking for an experienced all-rounder to work on the core Anvil platform, with a focus on the back-end. Our stack is mostly Clojure, Javascript, Python, Postgres, and container tools – but we're looking for someone who isn't afraid to jump into something you haven't used before.

You’ll be working with other seriously good all-rounders, including the founders (relevant PhDs, kernel contributors, builders of backyard dancing fountains) and senior colleagues (eg: Stu went from teaching Python in maths class to reverse-engineering our drag'n'drop editor in months), as well as our other developers and developer advocates. We're bootstrapped and profitable, with a small, smart, friendly and diverse team.

Building dev tools is great! We're solving problems we've experienced ourselves, our customers are developers just like us, and platforms have the most fun engineering problems.

For full job descriptions, and to hear what it's like working here, go to https://anvil.works/jobs.

We work hybrid (in the office Tue-Thu, wherever you like Mon/Fri). If you have questions, I'm a founder and my email's in my profile.

Tacton Systems | Multiple roles | Hybrid, Stockholm

Full stack Java, JavaScript / TypeScript

We make a Configure-Price-Quote SaaS for complex product portfolios. For example, one customer is Tetra Pak, that sells machines that build packaging (milk, juice, etc). These machines are like a two-story building with many variations, every aspect has to be well-defined and validated before it's ordered.

In our solution products can be modeled in detail with constraints, and during a sale options are chosen and validated, often visualized parametrically, pricing is done, and a quote is prepared. All based on the well-defined model.

It's a 30-year old company that started as a research startup, grew organically, and has a stable customer base. After a recent acquisition it's aiming to grow, therefore many positions are open. I started working here just a year ago, but I can say the work environment is healthy and relaxed, lots of competent people and everyone I interacted with so far have been very nice and professional.

Entourage | Founding CTO | Remote | Full-time

We're building the protocol layer for collective AI agent intelligence. Our core insight is enabling mutually distrusting agents to exchange and validate experiences via a shared memory layer, transforming isolated learning into compounded network intelligence (think Git/OSS for agent experiences). This is crucial infrastructure for the future agent economy. Incubated by Moonsong Labs (Kluster.ai, Moonbeam, Tanssi).

Seeking a hands-on, visionary CTO & Co-founder to architect our system (AI, distributed systems, data, infra), build the founding engineering team, and drive technical strategy. This involves deep work in multi-agent systems, collective learning, secure execution, and potentially novel consensus/incentive mechanisms.

Must have: Proven leadership in AI infra (CTO/VP/Founder/Lead Scientist). Expertise in GenAI/RL/DL/MLOps/PyTorch. Experience with agent frameworks (LangGraph, AutoGen, etc.) and distributed/federated AI concepts. MSc required, PhD strongly preferred. Strategic thinker passionate about building developer ecosystems.

Nice to have: Blockchain/Web3/tokenomics experience.

Chorus One | https://chorus.one/careers | Platforms Engineer | REMOTE (Switzerland ± 6 hours)

Chorus One operates validators on many proof-of-stake blockchains (the ones where security is based on a Byzantine fault-tolerant consensus algorithm rather than wasting energy). We are hiring for several roles, but the one I will highlight is what we call Platforms Engineer. Some companies call this Site Reliability Engineering or Devops.

The main thing we do is take upstream software, build it, run it on our infrastructure, and then monitor it and optimize that setup. Some things that make this interesting are:

* Building automation that enables us to do this for many networks (70+ currently). * Doing this with high uptime, building automation for failover, etc. * Working with software that is on the one hand cutting-edge and doing interesting things (consensus algorithms, distributed systems, cryptography), but on the other hand that means it’s immature and often not easy to operate and monitor. Often we have to build custom tools, and dive into the source code of the project. We contribute patches upstream when it makes sense. * Some of these projects are exercising the limits of what a machine can do, we have to do some low-level investigation that requires understanding of what the Linux kernel and network hardware are doing to properly identify what’s going on. We do have a small cloud footprint, but run primarily on bare metal. We are looking for people who can not just configure services offered by the public clouds, but who deeply understand what lies below; people who could build their own cloud. That sounds a bit pretentious and it’s not exactly what we do, but it does involve many of the same aspects.

A recent example of what I personally find fascinating: last month Ethereum’s Holesky testnet experienced loss of liveness. This is a real-world, globally distributed system that implements Byzantine fault tolerance, with multiple independent implementations of the protocol. Several of these implementations had a bug in an update, which caused a split in the network. The protocol is designed to handle this situation in theory, but in practice it is triggering previously unexplored failure modes in the implementations, that are hard to test for in synthetic small-scale tests. I think there are very few places where you get to be involved in a planet-scale distributed system exhibiting “interesting” behavior, especially one that is not in control of a single entity. Of course, there is also the less fun part that the testnet was broken, alerts are firing, and it was hard and chaotic to coordinate a fix when the network is not controlled by a single entity. Fortunately it’s a testnet.
