About Mesh

At Mesh, our mission is to enable consumers to pay and be paid with any asset. Today, trillions of dollars in tokenized assets exist but remain largely unusable for everyday commerce. Mesh is bridging this gap by making crypto payments reliable, useful, and ubiquitous. We combine a powerful orchestration engine with a seamless consumer app to unlock liquidity for the world. Backed by leading investors like PayPal Ventures, Paradigm, and Galaxy Ventures, we are building the infrastructure for the next era of the global economy. Join us!

Overview

We are seeking a talented and experienced Senior Full Stack Software Engineer (Web3) with a strong background in building modern web applications and scalable backend systems. As a member of our team, you will play a crucial role in designing, developing, and maintaining our innovative software solutions, including integrating Web3 functionality such as wallet connections, signing flows, and on-chain/off-chain interactions. Mesh is a global company with headquarters in San Francisco, California USA. This candidate will work closely with the Engineering and Product teams spread across North America, Europe and India.

What You'll Do

• Design, build, and operate production-grade Web3 systems used by real customers and assets at scale.
• Own features end-to-end across frontend, backend, and on-chain components (with depth aligned to your strengths).
• Lead the design and implementation of complex workflows involving wallets, transactions, settlements, and orchestration.
• Partner closely with product, design, and external teams to turn ambiguous requirements into robust technical solutions.
• Improve system reliability, security, and performance across distributed and on-chain components.
• Mentor other engineers and contribute to engineering best practices, architecture reviews, and technical direction.

Who You Are

• 5-7+ years of professional experience as a Full-stack Web3 Engineer with production experience across frontend, backend, and on-chain components, comfortable owning systems end-to-end.
• Hands-on experience with Web3 building blocks, such as wallet connectivity/integrations, dApp development, blockchain RPCs and indexing, and/or on-chain/off-chain payment & settlement flows.
• Familiar with DeFi primitives (e.g., DEXs, swaps, lending, trading platforms) and how they work in real systems.
• Experience with some combination of:

+ Modern frontend frameworks (e.g., TypeScript, React, Redux)

+ Backend services and APIs (e.g., C#, Node.js, Go, Java, or similar)

+ Smart contracts and on-chain interactions (e.g., Solidity)

• Strong understanding of the transaction lifecycle (signing, submission, execution) and a security-first mindset when designing Web3 systems.
• Solid fundamentals in building scalable, reliable, observable distributed systems (monitoring, logging, tracing, performance).
• Frontend-leaning or backend-leaning profiles are welcome, as long as you have shipped Web3-enabled systems in production and want to expand your scope over time.

Why You’ll Love It Here

At Mesh, you're not stepping into a typical role—you're joining a rocket ship in mid-liftoff. You'll tackle complex, meaningful problems that actually move an industry forward, working alongside a sharp, motivated team that moves quickly, collaborates deeply, and expects everyone to operate with ownership. This is the kind of place where you'll see your work ship fast, make real impact, and be able to point to something and say, "I built that." You'll grow fast, level up your skills, and get a front-row seat to how a high-growth company scales from the inside, with competitive comp, solid benefits, and room to stretch your craft all coming standard. If you're energized by building, learning, and shaping something big—this is where you'll want to be.

In-Office Expectations

Employees based in our San Francisco, New York, and Bangalore hubs are expected to work from the office at least 40% of the time (approximately two days per week). This expectation may vary slightly depending on role, team, and business needs. Certain roles that require closer cross-functional collaboration or operational support may have additional in-office requirements, which will be discussed during the interview process. Our hybrid approach is designed to balance meaningful in-person collaboration, team building, and real-time decision-making with the flexibility to work remotely. We believe this structure supports strong execution while preserving autonomy and focus time.

How We Care For Our Team

We believe great work happens when people feel valued and supported. That starts with competitive salary and equity that grows as you and the company grow, plus comprehensive health coverage for you and your family. We offer unlimited PTO—and we mean it. Take the time you need to recharge and show up at your best.

We're invested in your growth with a dedicated budget for courses, conferences, and certifications. Work from wherever you're most productive with our remote-friendly approach, and count on having the top-tier tools and equipment you need to do exceptional work.
