Job description:

We’re looking for a senior solutions engineer, highly experienced with Typescript & React, and familiar with Ethereum smart contract libraries. They will lead the development of our primary customer-facing interface – the `taco-web` encrypt/decrypt API and library, written in Typescript – see We aim to broaden `taco-web`’s utility by increasing its compatibility with various applications and stacks (e.g. mobile-first, IoT, multi-chain, etc.). In doing so, we intend to bring TACo’s affordances – censorship-resistant end-to-end encryption – to users beyond the blockchain world.\ \ Our mission is to rid popular tools, services and applications from corporate/state surveillance, enable true sovereignty over one’s data, and permanently protect the right to private communication & data sharing. If you’re a good fit – and genuinely passionate about this mission – send in your resume, GH profile, and a relevant TS code sample that you’re proud of. No recruiters, please. **Responsibilities:** * Own and increase the utility of the `taco-web` library & API by adding more functionality, increasing compatibility with target applications, and improving developer experience. * Work with TACo’s adopters and prospective adopters to optimize the service and protocol, such that it best fits their evolving requirements and priorities. * Write robust, security-first code that will safeguard and facilitate the sharing of sensitive data in adversarial environments. * Build example web & mobile applications that feature trust-minimized access control as a primary value proposition (e.g. a decentralized dropbox for archiving highly sensitive payloads). **Key Competencies:** * (> 4 years) Deep knowledge and proficiency in Typescript, Javascript & React. **Experience building TS-based libraries and/or APIs, not just TS-based front-end applications.** * (> 1 year) Experience working with Ethereum, Polygon and smart contract libraries (e.g. viem, Ethers.js, Web3.js). * (> 2 years) Experience with DevOps, CI/CD processes (e.g. CircleCI), Git, automated testing, and other software development best practices. * (> 2 years) Experience with solution engineering, open source development & doc writing. * Verbal and written technical English. **Bonus Points:** * Familiarity with React Native and adjacent mobile technologies. * Familiarity with Python, Rust, Solidity & WASM. * Experience with EVM L2s and non-EVM networks. * Familiarity with distributed infrastructure & service-layer protocols (e.g. access control, storage, DIDs). * Familiarity with public-key cryptography and related cryptosystems. * Experience (professional or amateur) in security engineering, AppSec & InfoSec roles (hackers welcome). * Experience with subgraphs and GraphQL. \ **Employment parameters:** Global annual salary range: **$120-160k**, depending on experience & seniority. Token allocation: Up to \*\*3m \*\*[**T**](https://coinmarketcap.com/currencies/threshold/) / \~0.03% supply. Capped at $400k pre-vest value, 6-12 month performance-based cliff. Compensation: Via Deel for international contractors (including b2b). Via Gusto/Humi for residents of US/Canada. * Unlimited vacation. * Expensable trips to relevant events (Devcon, Devconnect, ETHGlobal, etc.). * Yearly retreat. **Interview process:** 1. Motivation interview → 2. Technical interview(s) → 3. Compensated assignment (4-6h) → 4. Offer \ **Company & product background:** NuCypher is one of two founding teams of the [Threshold Network](https://threshold.network/) (market cap \~$250m), which hosts tBTC (TVL: $200m), TACo, Random Beacon & tUSD. Since 2017, NuCypher has pioneered cryptographic primitives for end-to-end encrypted data sharing, including Proxy Re-Encryption and Threshold Access Control (TACo), novel cryptoeconomic mechanisms (e.g. [Stable Yield](https://forum.threshold.network/t/tip-003-threshold-network-reward-mechanisms-proposal-i-stable-yield-for-non-institutional-staker-welfare/82)), and original network/governance architectures, including a historic on-chain merger with Keep. \ \ [TACo](https://threshold.network/build/taco/) is our flagship product – an **access control** plugin & API, relevant to virtually all Web3 app/stacks that handle private data. The TACo access control service: * launched on Mainnet in January 2024. * is running on over 125 nodes with \~$60m of collateralized economic security. * has revenue-generating adopting developers with diverse use cases, and major web3 infrastructure partners (Ceramic, Irys, ArFS, Textile, Unlock, others). * unlike competitors, has been fully decentralized from genesis – the very first byte of data was encrypted under a trust-minimized cryptosystem and managed by distributed, permissionless cohorts of nodes.
