Aetherum.ai

2 days ago

## Company Description **Aetherum** (aetherum.ai) is building B2B crypto-collateralized lending infrastructure purpose-built for NCUA-regulated U.S. credit unions. We give credit unions the tools to offer crypto-backed loans to their members — with AI-powered underwriting, on-chain compliance, and institutional-grade custody architecture that keeps assets in the credit union's direct control. 5 patents pending. Live platform. Active partnerships. We're solving a problem no one else is built to solve. ## Role Description This is a foundational **Senior Engineer** role based in the San Francisco Bay Area (hybrid). You won't be joining a large team — you'll be the engineer who helps take Aetherum to its production-ready MVP deployment. That means owning real architecture decisions, working directly with the founder, and building on a live platform with paying infrastructure partners already in place. ## What You'll Own - **NestJS/TypeScript backend and React frontend** (you're extending, not starting) - **On-chain compliance architecture** (ERC-3643, Solidity, Sepolia → mainnet path) - **Crypto collateral architecture** across multiple asset types including XRP and stablecoins — with custody rails that keep assets in the credit union's direct control - **AI-powered underwriting pipeline** (Python microservices) - **Infrastructure decisions** you'll defend to regulators and investors ## The IP You'll Be Building On 5 patents pending across the core of what makes Aetherum defensible: 1. **DACS™** — proprietary risk assessment model scoring crypto-collateralized loan eligibility across 10 pillars, purpose-built for NCUA-regulated environments 2. **FHE-DACS** — Fully Homomorphic Encryption layer enabling privacy-preserving risk scoring without exposing member financial data 3. **DACS-Driven Dynamic LTV** — on-chain enforcement of per-member loan-to-value ceilings derived from DACS scores, written to the blockchain at origination 4. **ERC-3643 CUMember On-Chain Identity** — compliance module tying credit union membership, jurisdiction, and KYC status to an on-chain identity standard built for institutional lending 5. **TPSOE/DACS Methodology** — the underlying scoring and optimization engine This isn't a crypto app with a compliance checkbox. The compliance architecture is the product — and you'll be the engineer who extends and defends it. ## Qualifications - 7+ years full-stack engineering, with at least 2 in Web3/blockchain - Proficiency in TypeScript, NestJS, React, Python, and Solidity - Experience shipping in regulated fintech, crypto infrastructure, or B2B SaaS - Familiarity with MongoDB, Redis, and API-first architecture - Strong understanding of on-chain identity, compliance modules, and smart contract security - The kind of engineer who asks "why" before writing a line of code - Remote / Based in the San Francisco Bay Area ## What This Is This is an early-stage, equity-heavy role. If you want a big salary and zero ambiguity, this isn't it. If you want to own the technical direction of a company solving a real problem in a space no one has cracked yet — let's talk. www.aetherum.ai 📩 **Apply:** AetherumDev@aetherum.ai *When applying, mention the word **CANDYSHOP** to show you read the job post completely.*

Full-Stack Software Engineer

Ondo Finance

13 days ago

## Full-Stack Software Engineer **Location:** Remote (US) **Department:** Software Engineering **Work Type:** Remote **Employment Type:** Full-time ### About the company Hi, we're Ondo Finance. Our mission is to provide institutional-grade, blockchain-enabled investment products and services. We have both a technology arm that develops decentralized finance technology, and an asset management arm that creates and manages tokenized funds. We were the first company to tokenize exposure to US Treasuries, and have since expanded into several other assets. We are also focused on incubating protocols that can support both tokenized real-world assets and traditional crypto. Founded by folks from Goldman Sachs Digital Assets Team, we’re backed by some of the best investors in the world including Founders Fund, Coinbase Ventures, Pantera Capital, Tiger Global, and more. We are currently the leaders in the space in terms of AUM and are well capitalized to continue growing the firm. We're fully remote, with team members across the U.S. ### About the role Our Web team builds the applications, APIs, and underlying systems behind Ondo’s most important product experiences, giving users access to complex investment products across chains such as Ethereum, Binance, Arbitrum, Solana, Sui, and Aptos. We work across a broad surface area — from onboarding and mint/redeem flows for USDY and OUSG, to tokenized stocks and ETFs through Ondo Global Markets, portfolio experience, and bridge infrastructure. You’ll join a small, exceptional, and fast-growing team with real responsibility from day one. The scope is wide, the standards are high, and the work matters. This is a true full-stack role: you’ll move fluidly from product surfaces to APIs, backend systems, integrations, and core infrastructure, owning problems end to end and shipping with speed, rigor, and strong technical judgment. This is a role for engineers who want significant ownership and who care intensely about quality, pace, and craft. ### Responsibilities - Build and ship high-quality product experiences across the stack, with particular attention to speed, reliability, usability, and craft. - Design and implement clean, maintainable frontend systems and user interfaces in React and TypeScript. - Develop APIs, backend services, and integration layers that support product functionality and internal operations. - Work closely with Product and Design to turn ambiguity into clear plans, strong technical decisions, and fast execution. - Own problems end to end, from idea formation and technical design through implementation, iteration, and long-term maintenance. - Exercise strong engineering judgment in architecture, abstractions, tooling, and tradeoffs, with a bias toward simplicity and durability. - Use AI-native engineering workflows thoughtfully and effectively to increase velocity, improve quality, and strengthen execution. - Stay current on relevant advances in AI tooling, developer workflows, and crypto infrastructure, and apply them where they create real leverage. - Contribute to a culture of high standards, ownership, continuous improvement, and strong collaboration. ### Requirements - 1+ years of experience shipping high-quality software in production, ideally using Node.js, React, JavaScript, and TypeScript. - You are exceptionally effective with AI-native engineering workflows. You know the leading coding models, IDE copilots, agent tools, eval harnesses, benchmark patterns, and verification loops, and you use them thoughtfully to produce more and better work than a typical engineer. - Exceptional engineering ability and craft. You have strong product instincts, care deeply about quality, and consistently produce clean, durable, well-reasoned systems. - A history of operating at a very high level of ownership and intensity.
