Senior Software Engineer

Salary - 25-30 LPA

• Own the Architecture: Lead system design, API contracts, data modeling, security, scalability, observability, and cloud cost optimization across our products.
• Be Accountable for Reliability: Own uptime, latency, and throughput as usage grows, including participating in on-call rotations.
• Build Security In from Day One: Design secure PHI and payment flows, ensuring compliance is integrated into the architecture rather than added later.
• Drive Cloud-Native Delivery: Manage MERN-based platforms on AWS, GCP, or Azure using Kubernetes, CI/CD, infrastructure as code, and effective secrets management.
• Make the Hard Calls: Evaluate monoliths vs. microservices, event-driven architectures, third-party integrations, and build-vs-buy decisions. Make informed decisions, document the reasoning, and take ownership of the outcomes.
• Fix What's Broken: Participate in production incident resolution, identify root causes, and address performance, scalability, and availability issues.
• Set the Standard: Develop reference architectures, reusable patterns, and practical engineering guidelines for teams to follow.
• Stay Hands-On: Write code, lead design reviews, and review pull requests every week.
• Grow the Next Generation of Leaders: Mentor engineers and help develop future technical leads.
  

• 6.5+ years of software engineering experience, with a proven track record of owning architecture decisions.
• Experience managing live production systems serving 100,000+ users.

• Solid cloud architecture experience with AWS, GCP, or Azure.
• Experience in healthcare, fintech, payments, insurance, or another high-security domain.
• Deep understanding of distributed systems, API design, databases, and reliability engineering.
• Ability to communicate and defend technical decisions to both engineering teams and non-technical stakeholders.

• Hands-on experience with HIPAA, PHI handling, or PCI-DSS compliance.
• Working knowledge of Stripe, Braintree, or payment tokenization.
