Software Development Engineer III - Core CRM

We are building systems that operate at scale - high write volumes, real-time state sync, and burst traffic that doesn't politely warn before it arrives. We are looking for engineers who love owning systems end-to-end, care deeply about performance and reliability, and want to build things that don't just work - but last. This is not a ticket-execution role; it's a system-ownership role.

The core responsibilities for the job include the following:

Backend System Ownership:

• Design and evolve Node.js / NestJS services powering systems that operate at scale.
• Take architectural decisions that balance scale, cost, and long-term maintainability.

API Craftsmanship:

• Build well-typed, thoughtful REST contracts for high-volume flows.
• Think in terms of versioning, backward compatibility, and clean boundaries.

Data at Scale:

• Model and optimize MongoDB / Firestore schemas for high read/write workloads.
• Design atomic updates and consistency strategies for distributed systems.

Scalability and Resilience:

• Implement queues, caching layers, and rate limiting to handle burst traffic gracefully.
• Design for failure modes before they happen.

Frontend Integration:

• Ship modular Vue 3 UIs that efficiently consume APIs.
• Optimize realtime updates and state management (Pinia).
• Improve Core Web Vitals and perceived performance.

Observability and Production Ownership:

• Instrument logs, metrics, traces, and alerts.
• Participate in on-call duties.
• Debug real production issues.
• Drive post-mortems to meaningful closure (not just documents).

Mentorship and Leverage:

• Review code thoughtfully.
• Support junior engineers.
• Raise engineering standards across the team.

Requirements:

• 4+ years of professional engineering experience.
• Strong backend-heavy full-stack background.
• Deep comfort with Node.js + TypeScript.
• Experience building and scaling microservices (NestJS / Express).
• Modern frontend experience (Vue 3 or similar).
• Strong understanding of API design, Data modeling, Distributed systems tradeoffs, Concurrency and rate limiting.
• Real production debugging experience.
• Comfortable in cloud-native environments (GCP / AWS).
• CI/CD and containerization familiarity.

Nice to Have:

• Pub/Sub or message queue experience.
• Event-driven systems exposure.
• Domain-driven design familiarity.
• Performance optimization work.
• Experience reducing infra costs.
