- 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):

- 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:

- 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.
