Solidity Jobs in New York, New York, United States

Founding Engineer (Remote - Full Time)

Paros is an early-stage startup building the next generation of on-chain infrastructure, rethinking how organisations coordinate, automate, and earn yield on their digital assets. Built on public MPC rails, our system makes treasury operations autonomous and self-custodial, turning complex on-chain workflows into simple, automated decisions.

Our MVP is live in beta with strong early traction and ecosystem partnerships. We’re now expanding the founding team.

We’re looking for a founding engineer who loves to build from scratch, explore new systems, and push the boundaries of what’s possible in crypto infrastructure.

Primary Responsibilities

• Architect and build the core agent coordination layer on top of MPC rails.
• Design systems for automated strategy execution.
• Collaborate on product vision, architecture, and integrations with validators & DeFi protocols.
• Own early technical decisions, code quality, and infrastructure design
• Help shape the company’s technical culture, team, and roadmap
• You’ll take ownership of our technical foundation — from designing wallet integrations and automation systems to scaling institutional-grade infrastructure.
• You’ll work closely with the founder to shape the product roadmap, ship quickly in a live environment, and evolve the architecture as we grow from MVP to production.

Expected Qualifications

• 10+ years in backend or infrastructure engineering, comfortable building secure, scalable systems across TypeScript and systems languages (Go, Rust, or C++; Solidity a plus).
• Deep understanding of wallets, custody, or secure systems.
• Familiarity with DeFi, staking, or yield protocols.
• Excited by early-stage ownership and autonomy — from idea to deployment.
• Hands-on, proactive, and able to work independently in a fast-moving environment.
• Comfortable shipping MVPs or early-stage products and scaling institutional-grade systems.
• A team player, direct communicator, and nice person to work with — team culture matters to us.

Beneficial: Experience across both crypto and TradFi trading systems (e.g. exchanges, market making, risk, or brokerage systems)

Why Join Us

• Own a founding stake in a live startup redefining on-chain treasury automation.
• Shape key product and technical decisions from day one.
• Work alongside experienced founders, validators, and infra partners.
• Help design a system that will onboard the next wave of institutional capital into DeFi.
• Build something that will change how crypto organisations manage their assets.

If you enjoy thinking about scalable infra, smart automation, and how to make self-custody powerful and intuitive, you’ll fit right in.
