Remote Developer Jobs

Senior Front-End Developer

Posted: 4 months ago

The primary project of Heliax is the Anoma protocol (implemented in Rust). Anoma is a sovereign, proof-of-stake blockchain protocol that enables private, asset-agnostic cash and private bartering among any number of parties. In addition to Anoma, Heliax works on open-source projects which are part of the Anoma ecosystem, including but not limited to research in cryptographic libraries such as the MASP or Ferveo (written in Rust), and tools for high assurance validity predicates and arbitrary zero-knowledge circuits (Juvix, written in Haskell).

Heliax is a remote-first team, currently composed of cross-disciplinary members located around the world. All of our work is open-source. Our work culture is characterized by open-allocation, where team members have a high degree of freedom and autonomy in choosing when to work, what to work on, and whom to work with.


  • Architecture & building front-ends from scratch from design prototypes, wireframes and specifications.
  • Work very closely with the designer(s) on clarifying and providing bi-directional feedback on the designed wireframes, prototypes, and graphic assets.
  • Cross web ecosystem integrations, e.g. front-ends across applications, such as browser extension applications with web applications securely.
  • Lower level integrations of the applications with e.g. HSMs (e.g. with the Ledger APIs).
  • Organize project code bases & development processes in a scalable (allowing multiple people to simultaneously work on it), easy to test, perform quality assurances, & ready to integrate user feedback.
  • Work closely with the Comms & Product team, a team composed by designers, developers, and content writers on building, improving, and maintaining the existing & upcoming organization and project websites.
  • Developer-friendly documentation writing for both internal use and external use, as the projects and its libraries are/will be open-source.


Here are some of the projects that the team is working on:

Anoma Extension:

Description: A browser extension that works as the 1st step for all users. It is a Key Management System (KMS) that enables users to generate a master seed phrase and auto derive accounts on Anoma, later to access, manage the keys to e.g. sign transactions or use the viewing key. Sample of key features:

  • Support for file-based keys
  • Support for Ledger hardware wallet connectivity (keys are generated on the Ledger HSM)
  • Generation of master seed phrase
  • Auto derivation of keys for transparent and shielded accounts

Anoma Wallet:

Description: Anoma's browser based multi-asset wallet that allows users to send and receive transparent and shielded transfers. Sample of key features:

  • List all assets (any digital asset) on Anoma, which include NFTs.
  • Able to send/receive shielded and transparent transactions
  • Transactions can optionally be offsetting carbon
  • Display transaction history


  • You LOVE front-ends and have a passion for delivering delectable user experiences to a world-wide user base.
  • You feel aligned with Anoma’s vision and goals in bringing financial privacy and self-sovereignty to everyone in the world.
  • You have a bachelor degree in Computer Science or equivalent knowledge and experience.
  • Built and contributed projects in the web ecosystem for +5 years that have been deployed to an active user base, have mastered JavaScript (& TypeScript/ReScript, otherwise you’re able to pick it up quickly) and frameworks such as Vue/React (please submit examples of your past work, e.g. commits to Git repositories, URLs to websites that are active).
  • Ability to build applications that are performant and provide great user experiences across browsers (e.g. Chrome, Firefox, Safari) and devices (Desktop, Tablet, Mobile).
  • Ability to build secure integrations across web applications (e.g. browser extension <> web app), and across devices (e.g. HSM <> Device <> Web).
  • Ability to build web applications from scratch until production-readiness.
  • Knowledge or interested in learning about Rust and WebAssembly.
  • You’re an avid follower of the latest trends in the web development ecosystem and you’re excited about learning new technologies and contributing to them.
  • Self-organized and autonomous, expect minimal management in a flexible and remote work environment.
  • Verbal and written fluency in English.
  • Ability to do codebase walkthroughs, explain verbally your work in detail, and showing off your work via presentations and/or demos.

Bonus Qualifications

  • Worked on applications and end-user interfaces in the blockchain industry.
  • Have used applications or products of the blockchain industry before.
  • Interest and ability to learn and understand the codebases and the high level design of the Anoma blockchain protocol (Rust), understanding how zero-knowledge proof schemes and other cryptographic libraries (Rust), the SDK – or any other libraries or dependencies that will be integrated with the front-ends.
  • Experience with lower-level programming languages, e.g. C, C++, Rust (even better if you have any projects written with it), functional programming languages, e.g. Haskell or OCaml.
  • Organized and/or participated in developer meetups or conferences and enjoys being involved with open-source communities.
  • Fluency in other languages.


Preferred if residing within (+/- 3 hours) Central European time zones. Ideally someone who enjoys travel, nature and hiking. Often we find that products are best designed not in a meeting room but rather on a trail.
