We believe accountability creates trust, and clear ownership allows teams to move quickly without stepping on one another's work.

Raising risks before they become problems helps our team and our clients make better decisions. We value transparency over avoiding uncomfortable conversations. Get to It - Many of the challenges we solve have never been solved before. We don't wait for perfection; we start, learn, iterate, and move forward. Progress comes from taking the next concrete step. If you're excited by continuous learning and playing a real role in building the next generation of financial market infrastructure, you'll feel at home at Obsidian. ## About Obsidian Systems ## Company Overview - **One-liner**: Obsidian Systems is a software engineering consultancy that builds complex, high-assurance systems using advanced tools like Haskell and Nix for clients in blockchain, finance, healthcare, and other demanding domains. - **Entity Type**: Private (bootstrapped; no disclosed funding rounds) - **Headquarters**: New York, NY, USA - **Founded**: 2014 - **Founders**: Ali Abrar and Ryan Trinkle ## Core Business - **Primary industries**: Blockchain, finance, healthcare, government, transportation, education, infrastructure - **Target customers**: B2B – enterprises, blockchain foundations, startups, and research institutions that need custom, high-reliability software - **Mission or purpose**: “To raise the ceiling of what software engineering can do” by applying powerful ideas from programming languages, formal systems, and reproducible infrastructure to production environments. ## Products & Services - **Custom Software Development**: End-to-end services including product definition, UI/UX design, development, deployment, and operations support; platforms range from web and mobile to hardware wallets and blockchain validators. - **Kiln**: A GUI block validator and monitoring app for the Tezos blockchain. - **Tezos Baking & Wallet Applications**: Hardware wallet apps (Ledger) for Tezos and Sui blockchains. - **Nix (open source)**: A package manager and build system used internally to ensure reproducible, deterministic builds across all projects. - **Project Management & Engineering Leadership**: Obsidian provides engineering management, risk communication, and technical leadership on complex engagements. ## Market Standing - **Valuation**: Not publicly available (private company) - **Key Metric**: No publicly disclosed revenue; estimated to be a profitable consultancy with high-profile clients. - **Notable Clients and Partners**: Tezos Foundation (built Kiln, Tezos Baking/Wallet apps), IOHK (Cardano infrastructure), Groq (hardware/software support), Formation (marketing analytics), CBMM (brain research), law enforcement screening tool for mental health diversion. - **Growth Signals**: Continued work on major blockchain and AI hardware projects; active hiring for Software Engineer and Software Project Manager roles (as of mid-2025). ## Competitive Advantages - **Deep Haskell & Formal Methods Expertise**: Obsidian’s stack choice (Haskell, Nix) enables correctness guarantees and security that are difficult to achieve with mainstream languages. - **Reproducible Infrastructure**: Nix guarantees that every build, demo, and deployment is deterministic, eliminating “it works on my machine” problems. - **Client Track Record**: Successfully delivered high-stakes projects for Tezos, Groq, IOHK, and others, often at the bleeding edge of blockchain and systems programming. - **10-Week Delivery Model**: A disciplined process from ambiguous brief to production software, with clear timelines and proactive risk communication. ## Strategic Focus - **Deepening Haskell & Nix Ecosystem**: Investing in open source stewardship and tooling improvements. - **Blockchain & Decentralized Systems**: Continued work on proof-of-stake blockchains, ledger apps, and smart contract infrastructure. - **High-Assurance Systems**: Expanding into regulated industries (healthcare, finance, government) where correctness and security are critical. ## Why Work Here - **Engineering Culture**: Values depth, precision, intellectual honesty, and ownership.
