• Maintain high automated test coverage and engineering quality standards
• Conduct peer code reviews and enforce clean coding practices
• Troubleshoot production issues and performance bottlenecks efficiently

Monitoring, Reliability & Security

• Monitor systems using Datadog, New Relic, Grafana, Prometheus, or similar tools
• Implement logging, alerting, and observability best practices
• Apply secure coding principles aligned with OWASP Top 10 standards
• Ensure systems comply with GDPR, SOC 2, HIPAA, or other relevant compliance requirements
• Support uptime, resiliency, and disaster recovery initiatives

Collaboration & Technical Leadership

• Collaborate with product managers and designers to turn requirements into scalable technical solutions
• Lead technical discussions and contribute to architecture planning
• Mentor junior and mid-level engineers through reviews, guidance, and pairing
• Contribute to long-term technical roadmaps and engineering standards
• Participate actively in sprint ceremonies, planning, and technical estimation

What Makes You a Perfect Fit

• Strong full-stack engineer capable of owning features end-to-end
• Experienced in scaling systems and improving infrastructure reliability
• Hands-on problem solver who thrives in technical environments
• Strong communicator who collaborates effectively across teams
• Balances rapid execution with maintainable architecture and code quality
• Passionate about mentoring and improving engineering culture

Required Experience & Skills

• 5+ years of professional full stack software engineering experience
• Strong proficiency in JavaScript/TypeScript with React and Node.js
• Experience with relational and NoSQL databases (Postgres, MySQL, MongoDB)
• Hands-on cloud deployment experience using AWS, GCP, or Azure
• Strong understanding of Git workflows and CI/CD pipelines
• Experience building APIs, scalable applications, and production systems
• Strong debugging, optimization, and troubleshooting skills

Ideal Experience & Skills

• Experience leading architecture reviews and technical design sessions
• Familiarity with Infrastructure-as-Code tools (Terraform, Pulumi, CloudFormation)
• Background building SaaS or high-traffic applications
• Experience with microservices, event-driven systems, or serverless architectures
• Familiarity with Kubernetes orchestration and distributed systems
• Exposure to observability, performance engineering, and cloud cost optimization

What Does a Typical Day Look Like?
A Senior Full Stack Software Engineer’s day revolves around building features, improving infrastructure, and ensuring system reliability. You will:

• Join standups and align with engineering and product teams on sprint priorities
• Build full-stack features across APIs, databases, and front-end interfaces
• Review pull requests and mentor engineers through technical feedback
• Investigate and resolve bugs, outages, and performance bottlenecks
• Collaborate with product managers and designers on implementation strategies and UX flows
• Deploy updates through CI/CD pipelines and monitor infrastructure health
• Contribute to technical planning, architecture decisions, and platform improvements

In essence: you are both a hands-on builder and technical leader, ensuring systems remain scalable, reliable, secure, and continuously improving.
