Full Job Description

Company Overview

Oculus Systems Security is a forward-thinking security provider dedicated to enhancing safety through innovative technology and proactive physical security measures. We serve communities by bridging the gap between physical security and cutting-edge solutions, working closely with local law enforcement and clients to create safer environments.

About the Role

We're a security/field-services SaaS company running a live, revenue-generating platform for 70+ weekly users while simultaneously building its ground-up successor. We need an engineer who can operate independently across the full stack — mobile, backend, frontend, and database — and who is equally comfortable maintaining a legacy production system and building greenfield architecture.

This is not a "pick a lane" role. You'll split time between:

Maintaining and stabilizing our legacy production platform (PHP/Laravel + native iOS/Android), which handles active billing, government/legal compliance obligations, and daily field operations.
Building our next-generation platform(Python/Django + React + React Native), which will eventually replace the legacy system entirely.

You'll work directly with the Chief Technology Officer (CTO), who currently operates as sole engineer/architect across both systems — this role is designed to reduce that single point of failure and take ownership of significant chunks of both codebases.

What You'll Work On

Legacy Platform (current production system)

Laravel 5.8 / PHP 7.4 monorepo: multiple web apps (customer-facing permit portal, parking operations, HQ, admin/backend), a Laravel REST API, and native iOS/Android mobile apps
PostgreSQL on AWS RDS, EC2 instances behind an Application Load Balancer, CodePipeline/CodeBuild deployments
Payment/subscription processing via Authorize.net ARB, transactional email via Postmark
Bug fixes, incident response, targeted remediation work, and controlled feature changes — this system must stay reliable and compliant while it's being phased out

Next-Gen Platform (active build)

Multi-tenant SaaS ERP for managing distributed field/security personnel, clients, and client properties
Backend: Django 5.0 + Django REST Framework, django-tenants (schema-based multi-tenancy), Celery for background/scheduled jobs
Frontend: React
Mobile: React Native (iOS + Android) — this is the platform's field-worker interface, covering things like shift check-ins, offline data sync, geofencing, and photo capture with EXIF/compression handling
Data layer: PostgreSQL (Aurora), Redis (ElastiCache) for caching/queues
Infrastructure: AWS (VPC, ALB, EC2, CodePipeline/CodeBuild/CodeDeploy), JWT-based auth, service-layer architecture with clear separation between views/serializers/business logic

What We Need From You

Mobile app development experience is required — either native iOS/Android or React Native, ideally exposure to both. You should be comfortable with offline-first patterns, background sync, geolocation, and device permissions (camera, GPS).
True full-stack range: backend API design (REST), relational database design (PostgreSQL preferred), and frontend web development (React).
Comfort working across two different tech stacks simultaneously (PHP/Laravel legacy + Python/Django modern) without needing everything to be greenfield to do good work.
Experience with multi-tenant SaaS architecture is a strong plus (schema-based tenancy, tenant isolation patterns).
AWS familiarity: EC2, RDS/Aurora, ALB, CI/CD pipelines (CodePipeline/CodeBuild or equivalent like GitHub Actions/CircleCI).
Experience with payment/subscription systems (Authorize.net, Stripe, or similar) is a plus given the legacy system's ARB-based billing.
Strong independent judgment. This is a lone-wolf engineering environment — we need someone who asks sharp clarifying questions up front, doesn't need hand-holding once scoped, and can be trusted with production systems that have legal/compliance weight.

Nice to Have

Experience with field-service, workforce-management, or security-industry software
Familiarity with geofencing/location-based features
Experience migrating a legacy system to a new platform while keeping the old one live
Comfort with Jira-based sprint workflows (1-week sprints, story-pointed backlog)

Why This Role?

Direct ownership — you won't be one of fifty engineers touching a codebase; you'll be one of two, with real architectural influence
You'll see a full legacy-to-modern platform migration from the inside, not just inherit the aftermath

Pay: $60,000.00 - $140,000.00 per year
