Role: Lead / Principal Full-Stack Engineer

About the Role:

We're looking for a rare hybrid: someone who can architect at the whiteboard in the morning and ship production code in the afternoon. This is a hands-on technical leadership role for someone who has built things in startups, knows how ERP/SaaS ecosystems actually work in practice, and can lead a legacy-to-contemporary migration without losing a single week of uptime.

What You'll Do:
- Design and drive cloud architecture on AWS, covering scalability, security, and cost optimisation across our infrastructure.
- Lead migrations of legacy systems to modern architectures with minimal disruption to business operations.
- Write production code across our stack — PHP, Node.js, Flutter, and JavaScript — as an active individual contributor, not just a reviewer.
- Own code reviews, troubleshooting, and performance optimisation across services.
- Architect and maintain ERP integrations and workflows, understanding both the technical and business logic behind them.
- Set up and improve DevOps pipelines, CI/CD, containerization,



and infrastructure-as-code practices.
- Champion Agile delivery, keeping large-scale projects on time and within budget.
- Build in cybersecurity best practices from day one — secure coding, infrastructure hardening, access controls.
- Mentor engineers while staying close enough to the code to lead by example.

What We're Looking For:
- Proven experience in a startup environment — comfortable with ambiguity, fast iteration, and wearing multiple hats.
- Strong full-stack development skills in PHP, Node.js, Flutter, JavaScript, or equivalent modern frameworks.
- Solid hands-on experience with AWS (EC2, RDS, S3, Lambda, VPC, etc.) and cloud architecture planning.
- Familiarity with DevOps tooling (Docker, Kubernetes, CI/CD pipelines, monitoring/observability stacks).
- Understanding of cybersecurity principles and how to apply them across the stack.
- Experience delivering large, complex projects on sc
