• Implement security best practices (OWASP Top 10, secure API design).
• Ensure compliance with data privacy regulations (GDPR, SOC 2, HIPAA as relevant).

Collaboration & Mentorship:

• Partner with product managers and designers to translate requirements into technical solutions.
• Conduct code reviews, mentor junior engineers, and lead technical discussions.
• Contribute to architecture decisions and long-term technical roadmaps.

What Makes You a Perfect Fit:

• Hands-on builder who can ship features end-to-end.
• Experienced in scaling applications and optimizing infrastructure.
• Clear communicator and collaborative team player.
• Balances speed of delivery with long-term code quality and maintainability.

Required Experience & Skills (Minimum):

• 5+ years professional full stack development experience.
• Proficiency with JavaScript/TypeScript (React, Node.js).
• Experience with relational (Postgres, MySQL) and NoSQL (MongoDB) databases.
• Cloud deployment experience on AWS, GCP, or Azure.
• Strong Git workflow and CI/CD knowledge

Ideal Experience & Skills:

• Experience leading technical design sessions or architecture reviews.
• Infrastructure-as-Code skills (Terraform, Pulumi, CloudFormation).
• Background in SaaS or high-traffic web applications.
• Familiarity with microservices, event-driven systems, or serverless architectures.

What Does a Typical Day Look Like?

A Senior Full Stack Engineer’s day revolves around building features, reviewing code, and ensuring systems are reliable and scalable. You will:

• Join daily standups to review progress and align on priorities.
• Write code for new features, from designing the API to building the front-end interface.
• Review and merge pull requests, mentoring junior developers through feedback.
• Debug and optimize systems, addressing performance bottlenecks or outages.
• Collaborate with product managers and designers to refine requirements and UX flows.
• Monitor deployments and infrastructure health to ensure uptime and reliability.

In essence: you are both a hands-on engineer and a technical leader, ensuring applications are robust, scalable, and continuously improving.

Key Metrics for Success (KPIs):

• Features delivered on time and aligned with specifications.
• High uptime (≥ 99.9%) and system reliability.
• 80%+ code coverage with automated testing.
• Positive peer review feedback and reduced technical debt.
• Successful mentoring and upskilling of junior developers.
