[Hiring] Senior Backend Engineer @Scale Army Careers

Role Description

This role is open to candidates based in LATAM, Africa, and Eastern Europe. Please note that as this role supports U.S.-based clients, candidates must be available to work during U.S. business hours aligned with the client’s time zone.

As the platform continues to operate at significant scale across thousands of business locations, they are seeking a Senior Backend Engineer to strengthen backend architecture, integrations, data processing, performance, and production reliability.

The Senior Backend Engineer will work primarily within a mature, actively developed Laravel codebase and own backend features from initial requirements and database changes through development, deployment, and production monitoring.

A major focus of this role will be building and maintaining reliable integrations with external platforms, including systems that may provide inconsistent, duplicated, delayed, or unreliable data. The Senior Backend Engineer will design resilient ingestion and asynchronous processing workflows while troubleshooting complex production and data issues across multiple systems.

This is a deeply backend-focused position for an experienced PHP/Laravel engineer with strong database fundamentals, third-party API experience, practical AWS knowledge, and excellent production debugging skills.

The ideal candidate also actively uses AI-assisted coding tools while maintaining the independent engineering judgment necessary to validate, debug, and take ownership of everything they ship.

Qualifications

• 5+ years of professional backend development experience.
• 3+ years of hands-on experience with PHP and a modern PHP framework, with Laravel strongly preferred and Symfony also considered.
• Experience developing and maintaining production backend systems.
• Experience building and consuming REST APIs and integrating third-party services.
• Experience working with queues, background jobs, retries, failures, duplicate delivery, and timeouts.
• Experience building systems around inconsistent or unreliable third-party data.
• Experience working with Git and pull-request-based development workflows.
• Experience using Docker for local development.
• Experience using AI coding assistants on real production software.

Requirements

• Deep knowledge of modern PHP 8.x, object-oriented programming, and software design principles.
• Strong Laravel expertise with the ability to work effectively within a mature and actively developed codebase.
• Excellent relational database skills, including schema design, indexing, query optimization, EXPLAIN analysis, and diagnosing performance degradation.
• Strong understanding of asynchronous processing and the engineering considerations required for reliable queue-based systems.
• Able to design resilient third-party integrations that account for retries, idempotency, duplicate delivery, failures, and inconsistent data.
• Strong production debugging abilities with experience tracing complex issues through databases, logs, monitoring systems, and external integrations.
• Strong automated testing judgment with the ability to determine what should be tested and evaluate whether tests accurately validate expected behavior.
• Comfortable working with AWS infrastructure, particularly SQS, Lambda, ECS, S3, CloudWatch, and RDS/Aurora.
• Familiarity with MongoDB or DocumentDB alongside relational database systems is strongly preferred.
• Able to work effectively within multi-tenant SaaS architectures, including tenant isolation and white-label environments.
• Comfortable working with high-volume transactional systems, webhook ingestion, SMS, email, or similar messaging workflows.
• Strong written communication skills for tickets, pull requests, technical documentation, and production investigation write-ups.
• Experienced with AI-assisted development while maintaining the independent technical judgment required to validate and take ownership of production code.

Benefits

• Fully Remote | 9:00 AM - 5:00 PM EST
