About Midnight:

The Midnight Network is the first blockchain to offer programmable data isolation by leveraging zero-knowledge (ZK) proofs to enable selective disclosure of what information is visible on-chain and is designed to help developers implement necessary business policies, such as meeting regulatory requirements.

What the role involves:

We are looking for a skilled Procurement & Vendor Manager to help establish and shape the procurement function from the ground up for the Midnight group as an independent entity. This is an exciting opportunity to define and implement key procurement processes, optimize vendor relationships, and ensure the efficient acquisition of goods and services to support the company's growth and operations.

In this role, you will be responsible for setting up procurement systems and strategies from scratch, while ensuring the timely and cost-effective acquisition of essential resources.

  • Build and implement procurement systems and tools to streamline purchasing processes, track inventory, and improve transparency.

Vendor Management:

  • Establish and maintain strong relationships with key suppliers and vendors to ensure reliable delivery of goods and services.
  • Monitor and evaluate vendor performance, ensuring adherence to quality, delivery timelines, and contractual obligations.
  • Conduct regular reviews to optimize vendor partnerships and identify opportunities for better collaboration.

Budget and Compliance:

  • Manage procurement budgets and report on spending, savings, and procurement performance metrics.
  • Ensure compliance with legal, regulatory, and internal policies governing procurement and vendor activities.
  • Develop risk mitigation strategies to manage potential disruptions in the supply chain.

Collaboration and Stakeholder Engagement:

  • Collaborate with internal stakeholders across departments (product, architecture, engineering, delivery, finance, legal, IT, etc.) to align procurement activities with business needs.
  • Provide regular updates and insights to senior leadership regarding procurement strategies and progress.
  • Support cross-functional initiatives that depend on effective vendor partnerships or procurement outcomes.

Process Improvement and Innovation:

  • Implement best practices to improve the efficiency, transparency, and accountability of procurement processes.
  • Drive initiatives to enhance supplier diversity, sustainability, and ethical sourcing

Who you are:

  • Proven experience in procurement, vendor management, or supply chain roles (5+ years preferred).
  • Strong expertise in negotiating contracts, managing supplier relationships, and delivering cost-effective solutions.
  • Familiarity with procurement systems and software.
  • Knowledge of legal and regulatory requirements related to procurement.
  • Experience in implementing and optimizing procurement processes in a fast-paced environment.
  • Exceptional communication and interpersonal skills to build and maintain strong relationships with vendors and stakeholders.
  • Analytical mindset with excellent problem-solving skills and attention to detail.
  • Proactive, self-motivated, and able to manage multiple priorities effectively.
  • Team player with a collaborative approach to working across functions.
  • Bachelor’s degree in Supply Chain Management, Business Administration, or a related field (preferred).

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.
