    Friendly offer

    We are seeking a Junior Backend Engineer to join our team and help build scalable, performant, and reliable backend systems that power our products. As a Junior Backend Engineer, you will be responsible for developing and maintaining server-side applications, APIs, and databases. You will work closely with our product managers, front-end developers, and other engineering teams to deliver high-quality software solutions that meet our customers' needs.


    About Us:

    We are the cipher masters, the wizards of data verification, and the trailblazers of provable computing. At Herodotus, we're dedicated to realizing the original vision of blockchain technology: minimizing trust in centralized entities and empowering individuals with true data sovereignty.


    Our solutions like Storage Proofs and the Herodotus Data Processor, enable developers to write smart contracts that can verifiably retrieve data and perform compute over L1 State on L2s, L2 State on L1s, and L2 State on L2s, eliminating the necessity for asynchronous messaging. We want to provide developers with tools to create truly trust-minimized applications, moving beyond reliance on oracles or economic incentives. Furthermore, we're committed to helping scale blockchains to onboard the next generation of users and applications to web3.


    About You:

    You are a highly motivated problem solver, eager to tackle complex coding and engineering challenges head-on. You prefer to take a proactive approach rather than a reactive one. You are ideally a recent graduate who has engaged in hobby projects or participated in hackathons, demonstrating your passion for coding and learning.


    Key Requirements:

    • Experience with NodeJS and Typescript, with a good grasp of their core concepts.
    • Understanding of software design patterns and their practical applications.
    • Basic knowledge of Rust.
    • Experience working with relational databases like Postgres.
    • Familiarity with message queuing systems such as RabbitMQ and caching systems such as Redis.
    • Experience with integrating third-party APIs and building reliable systems.
    • Basic understanding of serverless architectures and event-driven programming.
    • Experience with containerization technologies such as Docker.
    • Familiarity with various algorithms and data structures.
    • Basic understanding of blockchain technology or a keen interest in the field.


    Good to Have:

    • Relevant work experience and/or Bachelor's degree in Mathematics or Computer Science
    • Basic knowledge of cryptography and security best practices.
    • Familiarity with AWS services such as Lambda, API Gateway, S3, and DynamoDB.


    Responsibilities:

    • Assist in the design and development of scalable, performant, and reliable backend systems that power our products.
    • Write high-quality, maintainable, and testable code using NodeJS, Typescript, Rust and other relevant technologies.
    • Collaborate with cross-functional teams to define and implement APIs, data models, and system architectures.
    • Optimize and fine-tune database queries, caching, and message queuing systems to improve performance and reduce latency.
    • Troubleshoot and debug production issues, and provide timely and effective solutions.
    • Stay up-to-date with the latest backend technologies, frameworks, and libraries, and identify opportunities to improve our systems and processes.
    • Learn quickly and take on increasing responsibilities, with opportunities for rapid promotion based on performance and skill development.


    If you are a passionate and eager engineer who enjoys working in a collaborative and fast-paced startup environment, we encourage you to apply. We offer competitive pay, flexible working hours, a dynamic and inclusive culture, and the opportunity to work on challenging and impactful projects.
