At Obsidian Systems, we’re not your typical software consultancy. Since 2014, we’ve been building unusually high-quality software by combining the best tools from both industry and academia. From functional programming and static analysis to distributed ledger technologies and AI, we stay at the cutting edge—not just for the sake of novelty, but because it helps our clients gain a true strategic edge.
We’re a team of engineers who value rigor, creativity, and curiosity. If you’re passionate about solving hard problems with elegant code, you’ll fit right in.
What You’ll Do
As a Software Engineer at Obsidian, you’ll work on challenging projects across diverse domains—fintech, blockchain, AI, data science, and more. You’ll collaborate with a fully remote, distributed team of experts to design and build software systems that are robust, scalable, and impactful.
Your work will involve:
Designing and developing new applications and systems
Writing clean, testable, and well-documented code
Participating in thoughtful code reviews and architecture discussions
Debugging, optimizing, and improving existing systems
Contributing to testing, CI/CD, and deployment processes
Exploring new technologies and applying them to real-world problems
Who You Are
You’re not just a coder—you’re a craftsperson who takes pride in building elegant, reliable systems. You thrive in a remote environment where initiative and clear communication matter just as much as technical skill. You have:
3+ years of professional software engineering experience
Hands-on experience in one or more of the following domains: fintech, blockchain, AI, data science, open-source, enterprise software
Documented experience in functional programming (strong preference for Haskell and/or Rust and/or the Nix Ecosystem)
A solid grasp of system design and architecture principles
Experience collaborating on distributed, fully remote teams
Strong written and verbal communication skills across time zones
Contributions to open-source functional programming projects
