Prometheum is building the first compliant ecosystem for blockchain securities. Blockchain securities are born on our network when a company raises capital on Prometheum’s issuance platform by offering their own Smart Security Tokens (SST). Those SSTs can then be freely traded on our system, where the Prometheum Blockchain tracks transactions for secure clearing and settlement within 24 hours.

This position will join the Issuer Platform team in building tools for investors, Broker Dealers, blockchain validators and other network participants. We are a remote-first team with contributors spread out in the US. This opportunity is for someone with experience working from home and effectively collaborating via modern group messaging and and video conferencing tools.

This Year

Blockchain software developer
blockchain node-js senior design Oct 18 2019

This job posting is for a blockchain developer. It is expected that candidates can demonstrate senior software engineering experience, including at least 2 years recent experience on blockchain projects.

Candidates with only academic blockchain experience will be considered, but knowledge of technologies and provable working code is essential.

You will be working on a hybrid public/permissioned blockchain in the security token space. More information can be provided to interested and experienced candidates.

It is expected that you have done at least one of the following:

  1. Worked in a substantial capacity on a blockchain project at the protocol level where your code has been shipped to a public (or widely used private) network.

  2. Worked on more than one distributed application where you have designed, developed and delivered non-trivial smart contracts and supporting application layer systems.

  3. Have worked on (non blockchain) distributed systems at an expert level and have developed an understanding of blockchain with some shipped blockchain code.

In addition, you must have:

  • Smart contract design, development and prototyping experience (including in Solidity)
  • Excellent understanding of blockchain fundamentals
  • Worked on blockchain projects for at least 2 years
  • Senior engineering experience (7+ years) in a related field

Preferably, you also have:

  • Shipped or worked on open source public blockchain networks
  • Familiarity (or better) with Rust
  • Experience working in more than one smart contract language
  • Experience deploying, managing and using blockchain nodes (blockchain ops)
  • Experience of cross-chain considerations (e.g. bridging, pegging, locking techniques)
  • Familiarity with Node.JS, Go or other contemporary server-side frameworks and languages

(Very) nice to haves:

  • Experience with Substrate or Polkadot
  • Experience on projects that use hybrid permissioned/public blockchain networks
  • FinTech experience (not necessarily blockchain)
