Senior Backend Engineer

Join Zerion as a Senior Backend Engineer to build scalable distributed systems and collaborate on Web3 solutions. Enjoy a flexible remote work environment with competitive benefits. We're looking for a Senior Backend Engineer to join our backend team at Zerion. This team builds and evolves the backend systems at the core of our products and customer-facing solutions.

• •Design, build, and maintain scalable distributed backend systems powering platform and product capabilities.
• •Own backend services end-to-end: from architecture and implementation to monitoring and long-term reliability.
• •Work closely with product and engineering peers to actively shape product decisions — not just execute specs.
• •Scope solutions with the clients building on our API: turn a vague request into a concrete proposal, and the proposal into a plan the team can build.
• •Build and evolve Web3 platform backend components, including protocol integrations, support for newly emerging blockchain networks, and reliable interactions with smart contracts.
• •Ensure high standards of code quality, performance, security, and observability.
• •Operate comfortably in a fast-paced startup environment, balancing speed and correctness.
• •Use AI as a core part of your engineering workflow — designing, reviewing, debugging and shipping with it.
• •Contribute to technical discussions, reviews, and mentorship within the engineering team.

• •Salary & Benefits: Receive a competitive salary, medical insurance, coworking membership, and additional benefits.
• •Unlimited Days Off and Flexible Work Schedule: Recharge and explore life outside the office with our flexible time-off policy and work schedule.
• •Remote Work Essentials: We provide all the necessary software and equipment to ensure you're fully equipped to work from home comfortably and efficiently.
• •Stock Options: Contribute to Zerion's success and watch your stock options become valuable.
• •Travel: Connect with your teammates around the world at industry events and our annual team offsite.
• •Distributed Team: Zerion is a fully remote team with members worldwide. Embrace asynchronous collaboration, find your own work rhythm, and enjoy a healthy work-life balance.

• •5+ years of experience designing and building distributed backend systems.
• •Strong knowledge of algorithms, data structures, and software design patterns.
• •Comfortable working in a fast-paced startup environment.
• •Strong desire to actively contribute to product evolution, not just implementation.
• •Comfortable working directly with customers — hearing a vague problem and coming back with a concrete proposal.
• •Hands-on, daily use of AI in your engineering work.
• •High standards for code quality, system reliability, and user experience.
• •Strong ownership mindset — you take responsibility for outcomes, not just tasks.
• •Clear and proactive communication in a distributed team.
• •Pragmatic decision-making: knowing when to move fast vs. go deep.
• •Ability to learn quickly and adapt.
