Senior Front-End Developer

Role Overview


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 cryptographic libraries such as the MASP and tools for high assurance validity predicates and arbitrary zero-knowledge circuits (Juvix).

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 Wallet:

    • Description: Anoma's browser based multi-asset wallet that allows users to send and receive transparent and shielded transfers.
    • Technologies: TypeScript, Rust, WASM, React
    • 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
      • 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
  • Support our various JAMStack sites:


  • 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 🏔.
