A Backend Full Stack Engineer is a software developer who specializes in building and maintaining the server-side logic, databases, and APIs of an application, while also having proficiency in front-end technologies. They are capable of working on both the backend and frontend parts of web applications, allowing them to develop end-to-end features and ensure seamless integration between the client and server sides. This role requires strong knowledge of programming languages such as JavaScript (Node.js), Python, or Java, as well as familiarity with databases, server architectures, and various web frameworks. Backend Full Stack Engineers often collaborate with designers, frontend developers, and other stakeholders to deliver complete and functional products.

What are the key skills and qualifications needed to thrive as a backend full stack engineer?

Familiarity with frameworks (like Express, Django, or Spring), version control systems (like Git), and cloud platforms (such as AWS or Azure) is typically required. Effective problem-solving, communication, and teamwork skills help you collaborate across disciplines and deliver robust solutions. These skills ensure scalable, maintainable applications and seamless integration between backend and frontend systems, which are critical for organizational success.

Re-posted 25 days ago

Job description

Reins is building an enterprise stablecoin account that looks and feels like a first-class business bank account, while giving companies the benefits of stablecoin rails and self-custody. Reins makes stablecoins operationally simple for businesses, providing familiar banking features such as ACH, wires (and global equivalents like SEPA), cards, multi-level permissions, approvals, and AML/compliance workflows-combined with stablecoin-native advantages like instant 24/7 global settlement, better control via self-custody, and access to lending, insurance, and exchange markets as DeFi infrastructure matures.
Role Overview
You'll work directly with founder and CEO Sebastian Delgado (co-founder of Fei Labs), taking ownership of meaningful chunks of backend, full-stack, and security work. The role is flexible:
  • Full-stack engineer (preferred)
  • Backend engineer
  • Product/frontend contributor (optional)

Focus areas are prioritized as follows: security & smart contracts, full-stack, backend, and product/frontend. Infrastructure/devops is not a current priority.
Backend & Integrations
  • Design and build backend services connecting custody, fiat rails, policies, and operational workflows
  • Implement and maintain APIs and services for ACH, wires, cards, permissions, AML/compliance workflows, and reporting
Smart Contracts & Security
  • Implement and review Solidity smart contracts, focusing on correctness, safety, and upgradeability
  • Contribute to threat modeling, security reviews, and audit/vendor management

Product & Full-Stack Work
  • Collaborate on the design and implementation of customer-facing applications (currently Dart/Flutter)
  • Translate user and operational needs into product and UX decisions, especially around permissions, approvals, and money flows

Security & Audit Participation
  • Own parts of audit/security review processes for your areas of the stack
  • Coordinate with external security firms
  • Build internal systems and processes with a security-first mindset appropriate for handling customer funds

  • Strong background as a backend or full-stack engineer, ideally in early-stage fintech (Plaid, Brex, Ramp, modern neobanks)
  • Experience with crypto infrastructure, wallets, or stablecoin projects
  • Proficiency in Solidity smart contracts or a willingness to contribute to security-critical logic
  • Familiarity with APIs, integrations, and operational workflows (ACH, wires, cards, permissions, AML/compliance)
  • Ability to collaborate on frontend/product work is a plus (Dart/Flutter experience beneficial)
  • Strong understanding of security best practices for handling customer funds
  • Excellent problem-solving, attention to detail, and autonomy in early-stage environments

Preferred Backgrounds
  • Early engineers at crypto infra/wallet/stablecoin companies
  • Strong backend/full-stack engineers from top fintechs who are crypto-native
