Narraduct | Trust Officers | Remote | Full time & Part time | https://narraduct.com/jobs/trust-officer/

Basically, we're looking for 3 people to document and test access, building and maintenance for many client projects or build out systems automating that. The role name is bad, it's essentially looking for sysadmins or devops people. This division operates like a trust and on a trigger (like client death), we will continue to operate their web systems. We have legal and financial structures to do this "forever", although things are at an early stage.

Send resumes to info @ our website with the subject line of "career"

Note, half of compensation takes form of bonuses. As most employees are remote around the world with different regulatory environments, we can't offer traditional benefits. Base compensation is ~80.000 USD.

Narraduct is a commodities focused consultancy and hedge fund, building tools for mining and energy companies, primarily in Central Asia and S. America. Knowledge of accounting, chemistry, geology or industrial engineering is a huge bonus. We appreciate knowledge of multiple languages and curiosity about exotic paradigms. More than anything, we look for people who will fit in and help us create value. We can make roles for good fits!

We primarily use Common Lisp, with some Go, Racket and Prolog running on Linux and BSD. Some client facing stuff may feature Tcl or Clojure. We are also looking for a graphic designer or ui/ux expert who like preweb style interfaces with prouser experiences.

Even though we don't have other roles currently listed, if this sounds fun to you, do send us an email!

StorPool | Senior Software Engineer - Storage Core (C/Linux) | Remote (UTC-1 to UTC+5) | Full-time | Multiple roles

StorPool is building the future of data storage. Our software runs at the heart of modern clouds, delivering <100µs latency, 113M+ IOPS per cluster, and 99.999% availability. We're profitable, self-funded, and our customers love us (NPS off the charts).

We're looking for a Senior Software Engineer to join our Core Storage team. You'll tackle genuinely hard problems: writing custom Linux drivers, optimizing lock-free data structures at nanosecond scale, building fault-tolerant distributed algorithms, and debugging issues that go all the way down to kernel internals. This isn't CRUD work - it's systems programming at its most challenging.

Competitive salary, fully remote, meaningful time off, and a yearly education budget to keep learning.

If you get excited about shaving microseconds off I/O paths and building infrastructure that simply doesn't break, we should talk.

MixRank (YC S11) | Software Engineers | 100% REMOTE (Global) | Full-Time 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.

To stand out, please highlight what makes you unique: passion for computing, curiosity and side projects, work ethic, niche research, etc.

Ideally you've already graduated, but if you still have one or more years left of school, please feel free to apply anyway, and if you're the right fit for the team we'll figure out a way to accommodate your schedule.

Zed Industries | North America, South America, Europe REMOTE | https://zed.dev/

Zed is a company for developers, by developers. All 3 of our founders have spent years in the trenches writing software and still do it almost every single day. We know the only way to build the world's best code editor is by equipping every single member of the team to do the best work of their career.

We've raised $42M (https://zed.dev/blog/sequoia-backs-zed) to support our ultimate vision, a new way to collaborate on software, where conversations about code remain connected to the code itself, instead of being tied to aging snapshots or scattered across different tools. The first step was creating a high-quality editor to serve as the user interface. Now this new investment lets us expand to tackle the next phase of our plan. We're developing a new kind of operation-based version control that incrementally tracks the evolution of your code with edit-level granularity, and we're integrating it into Zed to make collaboration, both with agents and teammates, a first-class part of the coding experience.
