Job description
Software Engineer, Backend Systems (Rust) | San Francisco | $185K–$300K + Equity
About the Opportunity
We're partnering with a fast-growing, VC-backed trading technology company in San Francisco to hire 3–5 Backend Software Engineers with production Rust experience. They're building the backend infrastructure for a real-time trading platform, systems where milliseconds matter, markets move fast, and getting it right has real consequences.
This is a chance to work on hard problems: risk engines that hold up in volatile markets, blockchain state machines that power trading and settlement, and distributed systems that stay consistent under pressure. You'll join a small, high-bandwidth team that works together in person, five days a week, and moves quickly.
What You'll Be Doing
- Building and maintaining risk and liquidation engines that manage exposure and improve capital efficiency when markets turn volatile
- Designing and implementing the blockchain state machines behind trading, settlement and risk operations
- Developing services that keep state consistent across asynchronous processes, using voting, consensus and coordination mechanisms
- Processing live market data and coordinating actions across trading venues, managing WebSocket streams and time-sensitive workflows
- Building high-performance REST and WebSocket APIs that power the trading interface with millisecond-level response times
What You'll Bring
- 2–4 years of experience as a backend software engineer, with in-depth, production-level Rust experience
- A genuine, demonstrable interest in trading or financial markets. This matters most to the hiring team, so tell us what draws you to markets.
- Experience building backend services for real-time, high-throughput systems
- Strong command of asynchronous programming (e.g. Tokio)
- Proficiency with a range of databases, including relational, time-series and key-value
- Startup experience, ideally in a VC-backed environment
- A performance-driven mindset and a preference for working closely with your team in person
Nice to Have
- Experience in FinTech, trading or blockchain
- Low-latency or trading-systems experience, whether at a trading firm or on Cloudflare-style infrastructure
- Personal side projects, especially in Rust or C. If you've built something you're proud of, we'd love to see it.
Tech Stack
Rust, Tokio, Distributed Systems, Blockchain, REST APIs, WebSocket APIs, Docker
The Package
- Base salary of $185,000–$300,000, depending on experience
- Competitive equity
- Full-time, on-site role, 5 days a week in the San Francisco office
Visa Sponsorship
Our client can support TN visas and H-1B transfers, including candidates currently on OPT moving to H-1B.
They can't support H-1B transfers for candidates in year 3 or year 6 of their H-1B.
Interested?
If you write production Rust, care about performance, and want to work on systems where markets and engineering meet, we'd love to hear from you. Apply with your CV, plus a short note on your interest in trading or financial markets and any relevant side projects.
Visa sponsorship record
No public sponsorship records foundWe didn't find H-1B, H-1B1, E-3 or green card (PERM) filings under the name Vermillion Analytics in the Department of Labor and USCIS data. That doesn't mean the job can't be sponsored — the company may file under a different legal name, be new to sponsorship, or sponsor a visa that isn't in these datasets (for example H-2B or J-1).
Tip: ask the recruiter early, in writing, which visa they sponsor and whether they cover the legal and filing fees.
Which visas can work for this job
Occupation: Software Developers (SOC 15-1252) — estimated from the job title.
- Mentioned in the listing
H-1B, OPT
- H-1B cap-exempt employer
Regular cap-subject employer — a new H-1B needs to win the lottery in March (unless you already hold cap-counted H-1B status).
- TN (citizens of Canada and Mexico)
This kind of role may fit the USMCA profession “Computer Systems Analyst (or Engineer, for engineering-degree holders)” — it depends on the actual duties. No lottery, no cap; you need the matching degree or license.
- E-3 (Australia) and H-1B1 (Chile, Singapore)
Same degree requirement as H-1B, but no lottery and a separate quota that is rarely filled.
- O-1 (extraordinary ability)
For candidates with awards, publications, press, a high salary or critical roles at distinguished organizations. No cap, no lottery; the employer files a petition.
- STEM OPT extension (F-1 students)
Requires an E-Verify employer. We didn't find this company in the E-Verify list — ask HR.
