I am building a DevOps team at a capital markets tech company most people haven't heard of — but some of the world's biggest financial institutions run on our platform. 300B+ messages/day. 99.99% uptime. Mostly on-prem, Linux, purpose-built hardware.
You'd be working on systems support, tooling, and helping build a custom observability platform in Python — because off-the-shelf monitoring doesn't cut it at this scale.
Capital markets / FIX experience is a plus, not a requirement. Appetite for learning is.
The vibe: small global team (US/APAC/EMEA), fully async, deeply technical. Leadership still codes. No hand-holding, no fluff.
Mainly focused on US and EMEA hires (we currently have people clustered in Belfast and North Macedonia); for APAC, we have solid leads. We don't have salary expectations to publish. We are open to different engagements given regional and your personal factors, including contract, W-2, contract-to-hire, etc.
Senior IC role, report to me directly.

Modern hardware supply chains run on spreadsheets, email, and PDFs. It's like fax woke up in 2025. We're fixing this with an AI-first procurement platform for aerospace, defense, and nuclear manufacturing.

The role: Own features end-to-end, build ERP integrations that sync POs and manufacturing data, real-time order tracking dashboards, and a user experience that people LOVE. Work directly with customers whose supply chains depend on what you ship.
Stack: TypeScript, React, Next.js, Hasura (GraphQL), PostgreSQL, Trigger.dev, AWS GovCloud, Pulumi, Elbow grease.
You: 5+ years shipping production systems, strong full-stack or frontend generalist who moves fast, thrive on customer feedback and direct impact, bonus: ERP integrations, B2B SaaS, or regulated industries
Traction: 5x'd customer count last year, $5M funding to date, landing massive defense/space logos. Small team shipping incredibly fast—you'll work directly with our founders (Isaac and myself).

THE MOST IMPORTANT UNSOLVED PROBLEM IN AI IS THE MOST POWERFUL OF ALL CAPABILITIES: ALIGNMENT.
Hi, I'm Emmett. You may know me as the founder of Twitch (YC S05), and as the (extremely) interim CEO of OpenAI.
I believe the question of how AI systems learn to understand themselves and others is one of the most consequential technical problems of our time. If we get it right, the agents we build today will become our friends and collaborators tomorrow. And the infrastructure required to train agents that are good at working in teams and societies will be extraordinarily valuable.
Softmax is building large-scale multi-agent, multi-policy environments that will benchmark AI agents – both our own and others – on their capacity for theory of mind, adaptive goal setting, and teamwork. We’re looking for the engineers who will make that possible.
The work is unusually hard. The problems are ambiguous and challenging. High autonomy, high expectations. You'll work directly with me and the rest of our small but mighty team.
If this sounds exciting, I’m looking forward to meeting you. E

Every time two companies in the physical economy need to exchange data, someone builds a custom integration by hand. Analysts, engineers, QA. All manual. Every time. Google "EDI" if you haven't. It's wild.
We built AI agents that do the whole thing: gather requirements in plain English, write the integration code, test it, deploy it, fix it when it breaks.
We have paying enterprise customers and more demand than we can keep up with.
You'd be the first engineering hire. Agent orchestration, durable execution runtime, self-healing infra, most of the important architectural decisions haven't been made yet.
The founders built a logistics startup from pre-seed to 400+ people. We've been dealing with broken integrations for years.
TypeScript, Effect-TS, Bun, PostgreSQL, K8s, AWS. Paid work day. Under 2 weeks to offer.
