About Provable

At Provable, our mission is to redefine trust and privacy in the digital world.

By creating tools that simplify the complexities of zero-knowledge technology, we empower developers to build applications that prioritize security, user control and scalability. We envision a future where privacy is not an afterthought but a fundamental standard, enabling a more secure and equitable Web3.

Our commitment extends beyond technology to fostering a vibrant, collaborative community of innovators. Through accessible resources, thoughtful design, and a focus on developer success, we aim to bridge the gap between cutting-edge blockchain technology and real-world applications. Together we’re not just building tools-we’re shaping the foundation for a private decentralized future.

Summary

Provable is searching for exceptional senior Rust engineers to help build privacy preserving zero knowledge protocols and products.

As a Provable senior engineer you will use your engineering talent to design, implement and maintain both cryptographic and distributed systems and help build privacy preserving products on top of those systems. Collaboration will be key. You should be able to work well with engineers, designers, and leadership to turn our products and technical vision into deliverables each quarter. You should be able to clearly and thoroughly communicate your ideas.

The Work

Distributed Systems Development: Engineer distributed system components such as consensus logic, memory-mapped databases, networking stacks, and synchronization logic to be performant, safe, and correct.

Cryptography Engineering: Maintain and optimize low level cryptographic logic, from signature schemes to zero-knowledge proof systems. You will be working in close collaboration with other mathematicians, so we do not expect you to be a cryptographer. 

Product Engineering: Help product teams integrate the protocols you work with into their products by encapsulating useful pieces of the protocols into easy to use interfaces and APIs.

Key Qualifications

  • 5+ years of software engineering experience

  • 2-3+ years of professional Rust experience

  • A strong foundation in blockchain concepts and ideally, experience contributing to a blockchain project

  • Low-level system programming and/or distributed systems design experience

Benefits

  • Monthly budget for expenses (home office setup & supplies, transportation, fitness & personal well-being, continued learning, etc.).

  • Comprehensive, top-tier healthcare coverage.

  • Flexible vacation policy.

  • Ability to attend major industry conferences and global events at the company’s expense.

  • Regular team off-sites and retreats.

NOTE: We cannot sponsor visas of any kind at this time.

Provable is committed to diversity in its workforce and is proud to be an equal-opportunity employer and to review all of our job postings to minimize biased language.

What is Zero-knowledge?

Zero-knowledge is a concept in cryptography that allows two parties to exchange information without revealing any additional information beyond what is necessary to prove a particular fact

In other words, zero-knowledge is a way of proving something without actually revealing any details about the proof

Here are some examples of zero-knowledge:

  1. Password authentication: When you enter your password to log into an online account, the server doesn't actually know your password. Instead, it checks to see if the hash of your password matches the stored hash in its database. This is a form of zero-knowledge because the server doesn't know your actual password, just the hash that proves you know the correct password.
  2. Sudoku puzzles: Suppose you want to prove to someone that you've solved a particularly difficult Sudoku puzzle. You could do this by providing them with the completed puzzle, but that would reveal how you solved it. Instead, you could use a zero-knowledge proof where you demonstrate that you know the solution without actually revealing the solution itself.
  3. Bitcoin transactions: In a Bitcoin transaction, you prove that you have ownership of a certain amount of Bitcoin without revealing your private key. This is done using a zero-knowledge proof called a Schnorr signature, which allows you to prove ownership of a specific transaction output without revealing the private key associated with that output.
  4. Secure messaging: In a secure messaging app, you can prove to your contacts that you have access to a shared secret without revealing the secret itself. This is done using a zero-knowledge proof, which allows you to prove that you have access to the secret without actually revealing what the secret is.
