Want a real challenge? Join the bright and passionate engineers at Intuition Machines as we transform security and machine learning online. We are a casual and fast-paced environment, with a talented team distributed around the world, hundreds of millions of users, and a rapidly growing customer base and product suite.
As a Senior Backend Python Engineer you will be responsible for developing solutions that fit with our existing codebases, as well as implementing and optimizing novel machine learning techniques for our various business problems. You will improve and drive our evolving systems, threat models, and CI/CD practice.
We have a flat and highly customer-focused process, so you should be comfortable interacting directly with large enterprise customers and startups alike when necessary, in conjunction with product, customer success, and sales teams.
What will you do:
- Prioritize, design, develop, deploy and operate secure, robust, scalable and fast back-end algorithms, logic and services.

- Knowledge of basic standards in Ethereum ecosystem (ERC-20, EIP-165, etc).
- Minimum of 4 years of hands-on experience in a similar role at a SaaS provider (Python experience).
- Minimum a year of experience working with Solidity and web3py.
- Expert in backend development in Python.
- Experience with orchestration platforms like Kubernetes, metrics-driven staged deployment systems, containerization, and microservice design.
- Familiarity with distributed systems and databases: queue-first architectures, sharding, etc.
- Demonstrated architecture engineering expertise (gather requirements, problem solve and recommend).
Nice to have:
- Experience or interest in blockchain technologies.
- Knowledge of NodeJS.
- Familiarity with security frameworks, attack vectors, botnets, OLAP at scale, and online + active learning systems.
- Willingness to learn and work across different technologies: Python, Redis, PostgreSQL, Kafka, Clickhouse, Kubernetes, Helm, AWS, Azure, JavaScript.
What do we offer:
- Ability to work with cutting-edge technology.

What is ERC20 example?
ERC20 is a standard for fungible tokens on the Ethereum blockchain
Here is an example of an ERC20 token
Let's say we create a new ERC20 token called ABC Token with a total supply of 1,000,000 tokens
Each token will be divisible up to 18 decimal places
To implement the ERC20 standard, we will need to define several functions, including:
- balanceOf(address): Returns the token balance of a specific address.
- transfer(address to, uint256 value): Transfers tokens from the caller's address to the specified address.
- approve(address spender, uint256 value): Approves a specific address to spend a certain amount of tokens on behalf of the caller.
- allowance(address owner, address spender): Returns the amount of tokens approved by the owner that the spender can transfer.
- User1 owns 500,000 ABC Tokens.
- User2 wants to buy 100 ABC Tokens from User1.
- User1 approves User2 to spend up to 100 ABC Tokens on her behalf.
- User2 calls the transferFrom() function with User1's address, his own address, and the value of 100 tokens.
- The transferFrom() function deducts 100 tokens from User1's balance and adds them to User2's balance.
