About Witness

Our core mission at Witness is to make digital ownership more accessible. Building out the infrastructure and developer abstractions to accelerate the adoption of our protocols and products is the core focus and problem at Witness. The product and tools you build will be instrumental in not only scaling our internal capabilities, but also extending access to digital ownership for developers globally.

As an engineer at Witness, you'll play a critical role in building out our foundational infrastructure in a fast paced startup environment. This will involve researching, designing, and implementing novel engineering solutions related to hybrid onchain/offchain systems. You will ship a lot of code, with the potential to work on things like indexers, databases, smart contracts, cryptography, and APIs all operating at a global scale.

Our current technology stack spans the following tools and providers:

• Onchain: Solidity (deployed on Ethereum/EVM L2s) + Foundry

• Backend services: Typescript

• Frontend services: NextJS App Router + Tailwind + tRPC

• All backend & frontend services hosted on railway.app

• Database/PostgreSQL hosted on neon.tech

About The Role

For the Senior Product Engineer role, we’re looking for the following experience and qualifications:

• Experience shipping production code in a language like Typescript, Rust, Python, Go, Solidity

• Excellent problem-solving skills and a strong sense of ownership

• Obsession with shipping code with a bias for self-reliance

• Past work experience spanning Web2 and Web3 systems

• 4+ years of experience shipping Typescript or Javascript for web based front end applications

• Comfort shipping code with the following tools: React, NextJS, Tailwind, Wagmi, Viem

• Hunger for pushing the boundaries of what's possible in crypto today, with a knack for quick iteration

• Familiarity with design principles and tools

About You

• A solid understanding of engineering principles. You enjoy building and shipping quality, resilient, and dependable services.

• A sense of grit to dive into a problem and own the implementation of solutions.

• Possess excellent communication skills for effectively conveying your perspective, ideas, problems, and solutions.

• A strong sense of ownership and prioritization when navigating the ambiguity of an early-stage startup.

• A motivation for accelerating the adoption of digital ownership beyond the current limitations of public blockchains.

Things to Know

We are an early-stage startup; our team dynamics are different from companies of other sizes and stages.

• We're a small team, with high ownership, who are not only passionate about what we do, but seek to be exceptional as well. Currently, our team consists solely of our 2 co-founders, Sina and Joe. There's a lot of stuff going on, and a lot of ambiguity.

• We prioritize having a strong, in-person culture in San Francisco for our founding team. We are open to team members who operate remotely on a case-by-case basis.

• We do NOT expect you to work all the time, but you’ll have to be diligent and hold yourself accountable regarding the boundaries for your work day. Depending on your location, you may need to be flexible to accommodate the schedules of other team members and clients.

• We want teammates who own it. We strongly believe that empowering everyone on our team with ownership is a key to our growth and success. We expect every team member to not only own decision making, but also own the success or failure that results from their decisions.
