Staff Backend Engineer

Staff backend engineer in New York to build Superstate’s internal transfer agent: chain-aware services, custodian APIs, and the infrastructure as code around an SEC-registered agent.

Blockchain Lab analysis

Public reporting and the employer’s own releases. Not a relationship with Blockchain Lab. Not a credit opinion.

Founded: 2023. Robert Leshner, of Compound, is the chief executive on the Series B coverage.
Base: New York City for this seat. Remote is not stated.
Status: Private. SEC-registered transfer agent, as The Block reported with the round.
People: Leshner is the public CEO. The posting says a small team. This brief does not repeat an unsourced headcount.

Superstate is what a Compound founder builds when the trade is no longer lending against crypto collateral but putting a regulated fund, and then a regulated equity, on a chain. The January 2026 round is the cleanest capital fact on this desk's new set: $82.5 million, named co-leads, a stated AUM threshold, a stated next product. Valuation withheld. That withholding is normal and annoying. Your equity, if any, cannot be priced from the articles.

The seat is older than the round. Lever's created date is 12 November 2024. The company has since raised, claimed a billion-plus in AUM, and announced an equity-issuance direction. A staff engineer who joins against a 2024 description of 'build an internal transfer agent' may be walking into a system that already exists, or into the equity-issuance build the round was for. Those are different years of your life. The posting still asks for deep Rust, 9+ years, and AWS. Pay is not disclosed. New York is the location.

Founders

Robert Leshner

Co-founder and CEO

Built Compound, then this. The January 2026 quote is about tokenization changing capital markets, and about hiring engineers, lawyers, and institutional finance. A staff backend engineer is the hiring he described. The open question is whether the 2024 req is that hire or a leftover.

The operating company

Transfer agent

Being a registered transfer agent is the regulatory fact that makes the codebase different from a DeFi vault. Shareholder registers, not just balances. If that bores you, the Rust will not save the interview.

What the company sells

Tokenized funds

The company's products. On 22 January 2026 it said AUM had passed $1.2 billion. That is the company's sentence that day, not a live mark.

The transfer agent

The job: an internal transfer agent, custodian APIs, and AWS infrastructure as code, in Rust. A shareholder record that is wrong is the incident.

Where the round said they are going

Beyond Treasuries, into SEC-registered equity issuance on Ethereum and Solana. The Block, quoting the company.

Series B

$82.5 million

This seat's pay

Not disclosed

9+ years and Rust are stated. A band is not.

Req age

Created 12 Nov 2024

Lever createdAt. Before the Series B. Confirm it is open.

22 Jan 2026
Series B
$82.5 million
The Block: led by Bain Capital Crypto and Distributed Global. Participants named include Haun, Brevan Howard Digital, Galaxy, Sentinel, Bullish, Hypersphere, Flowdesk, 1kx, ParaFi, and others. Use of proceeds: scale from tokenized Treasuries into onchain equity issuance. No post-money in that story.

What should change your mind

A req that predates the round by fourteen months.
No valuation on the round you would be joining after.
AUM is a company statement from January. It is not a guarantee the seat is funded.
Transfer-agent liability. The bugs are records, not latency.

Ask them

Is this the 2024 req, and what of the transfer agent is already in production?
What is the post-money, or at least the strike on a new grant?
Does the equity-issuance plan change this seat's scope?
New York: how many days in office, and which entity?

A reading of the work

Blockchain Lab analysis. These lines are a reading of the advertisement. They are not extra hiring requirements.

The Lever record was created on 12 November 2024, before the Series B. Confirm the seat is still open.
A transfer agent’s bug is a shareholder-record bug.
Rust on the posting is not a suggestion.

Still not disclosed

Compensation, unless a figure appears in the header. None of these eighteen postings stated one.
Closing date, and the day the role was first published. The board timestamp is an update.
Visa sponsorship, on-call, and the employing subsidiary.

Not a recommendation to apply. Not an employer assessment. Figures from public reporting move, and a database is not a filing. How this desk labels evidence. Report a listing.
