Senior B2B API Engineer

ABOUT THE ROLE HiveRx is a production pharmacy operations platform built for regulated compounding environments. The platform also has a major opportunity to support business-to-business API use cases that can expand how partners, internal systems, and future product capabilities interact with HiveRx. This role owns the B2B API end to end: architecture, implementation, documentation, partner-facing behavior, internal coordination, and delivery predictability. The work is less dependent on deep pharmacy background than some platform roles, but it still requires respect for regulated healthcare data, operational consequences, and long-term platform integrity. This is not a generic endpoint-building role. API design creates long-term product commitments. The person in this role needs to build stable interfaces that are secure, documented, testable, and aligned with the platform rather than one-off shortcuts. WHAT YOU'LL DO Product Engineering Own the design and implementation of B2B API capabilities for HiveRx Define API resources, authentication patterns, authorization boundaries, request/response contracts, error handling, rate limiting, and versioning strategy Build durable Laravel backend services that fit the existing platform architecture Create predictable integration surfaces for partners, internal systems, and future product capabilities Write automated tests that protect API behavior and prevent regression Feature Specification & Research Translate business and partner needs into detailed, unambiguous API specifications Research integration patterns, security requirements, data contracts, partner workflows, and platform constraints Produce documentation and examples that make API behavior clear to external and internal consumers Lock architecture and scope before build momentum begins Identify when partner needs require product decisions rather than one-off technical exceptions Product & Platform Ownership Own API work from scope definition through release Coordinate with product, platform, security, and operational stakeholders as needed Handle healthcare and pharmacy-adjacent data with appropriate care for privacy, access control, auditability, and traceability Ensure API behavior does not bypass important workflow controls or create hidden operational risk Establish a predictable release timeline and make risks visible early WHAT WE'RE LOOKING FOR Technical Strong backend engineering experience with production APIs Strong PHP and Laravel experience, or deep backend experience with the ability to become productive in Laravel quickly Experience designing RESTful APIs or similar partner-facing integration surfaces Strong understanding of authentication, authorization, token management, API security, validation, error handling, rate limiting, and versioning Comfortable with database design, service boundaries, queues/jobs, observability, automated testing, and technical documentation Domain Experience working in or building software for regulated industries is preferred Healthcare, pharmacy, regulated data, logistics, ERP, or other integration-heavy environments are relevant backgrounds Must understand privacy, access control, auditability, and data integrity concerns in systems that exchange sensitive operational data Able to learn enough of the pharmacy domain to avoid dangerous assumptions AI & Tooling Comfortable using AI tools as a productivity layer for API design, implementation, documentation, and code review Able to critically evaluate AI-generated code, specs, and documentation before relying on them Understands where AI output requires extra scrutiny: edge cases, security boundaries, regulatory logic, data handling, and integration contracts Writing & Communication Strong technical writer; your API specs and documentation require minimal clarification Able to communicate clearly with both engineers and non-technical stakeholders Detail-oriented without being slow; you know when an API contract is ready to build Comfortable pushing back on vague requirements, unsafe shortcuts, and unstable interface designs Mindset Senior ownership mentality; you can own a major technical track without constant direction Precise, structured, and documentation-oriented Comfortable with ambiguity; able to impose structure on it Focused on building stable interfaces that other teams and partners can trust STACK Backend PHP 8.4 / Laravel 13 · MySQL via Eloquent ORM · Laravel Horizon, Scout, Sanctum, Reverb ·Saloon for API integrations Frontend Vue 3 / Inertia.js v2 · Tailwind CSS v4 / Vite Testing Pest v4 / PHPUnit 12 Infrastructure Kubernetes on AWS BENEFITS Full-time, employed directly by Revelation Pharma.
