Software Engineer, Backend Systems
Company: Fullstack
Location: New York, NY (on-site)

About Fullstack
Fullstack is building a single front end for crypto trading. Today retail traders are spread across multiple front ends, browser-extension wallets, bridges and a growing list of venues. Fullstack brings perpetuals, cross-chain spot and prediction markets into one portfolio-margin trading experience with a single unified balance, extending USDC collateral to the venues of each user's choice.
One co-founder built Insilico Terminal, which the company describes as the leading order execution and management system for centralized exchanges; the other ran one of the top on-chain and centralized-exchange high-frequency trading firms. Fullstack has raised $15M+ and has a team of about 10.
The Role
Fullstack is looking for a backend engineer with production Rust experience to help build the infrastructure behind its real-time trading platform: risk, settlement, market data and the APIs traders depend on. This role suits someone with strong asynchronous programming, solid systems knowledge and a performance-driven mindset who thrives in a collaborative, in-person environment.
What You Will Do
- Build and maintain risk and liquidation engines that improve capital efficiency in volatile markets.
- Design and implement the blockchain state machines that power trading, settlement and risk.
- Build services that keep state consistent across asynchronous processes using voting, consensus and coordination.
- Process live market data and coordinate actions across trading venues over WebSocket streams.
- Build high-performance REST and WebSocket APIs with millisecond-level response times.
What You Bring
- 2-4 years as a backend software engineer
- In-depth production experience with Rust
- Strong asynchronous programming (Tokio a plus) and distributed systems knowledge
- A performance-driven mindset for latency-sensitive, real-time systems
- Ability to work on-site in New York

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 Transparent Search Group 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: Computer Systems Engineers/Architects (SOC 15-1299).
- Mentioned in the listing
H-1B
- 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.
Salary vs prevailing wage
Level IV (fully competent)Computer Systems Engineers/Architects · New York (state median of areas). Annual prevailing wages set by the Department of Labor (OFLC).
| Level | Prevailing wage | H-1B lottery odds* |
|---|---|---|
| Level I | $60,196 | ~15% |
| Level II | $80,496 | ~31% |
| Level III | $99,351 | ~46% |
| Level IV | $116,574 | ~61% |
This job pays $185,000–$300,000 a year — that's Level IV (fully competent). In the wage-weighted H-1B lottery a Level IV registration gets 4 entries; estimated selection chance about 61% — better than average.
* Odds are DHS projections for the FY2027 wage-weighted lottery (actual results vary by year and employer). Since the FY2027 cap season the H-1B lottery is weighted by wage level: Level I = 1 entry, II = 2, III = 3, IV = 4. The level is set by the offered wage against the prevailing wage for the occupation and worksite. Separately, a $100,000 fee for new H-1B petitions for workers outside the US was announced in 2025; as of September 2026 a federal court ruling keeps it unenforceable while appeals continue — check the current status.
