Software Development Engineer III (CRM - Opportunities - AI)

The role

You will own the CRM Opportunities product end-to-end, focusing on the backend. This covers the data models, APIs and distributed workflows behind pipelines, stages, automations, reporting and integrations. You will also build AI-assisted features on top of existing AI capabilities.

What you will do

• Own the full lifecycle of the Opportunities backend, from business and customer needs to production-grade services
• Design and evolve the data model for pipelines, stages, deals and associated entities
• Build and scale APIs, event-driven workflows and background jobs for high-volume writes, automations and integrations
• Handle distributed systems concerns such as idempotency, eventual consistency, race conditions and noisy-neighbor isolation
• Improve performance and reliability of large pipelines through indexing, sharding, caching and query optimization
• Build AI-assisted surfaces on top of existing AI capabilities, including context assembly, cost and latency budgets, graceful degradation and output quality feedback
• Ship end-to-end when needed, including UI changes in Vue
• Instrument the system with logs, metrics, traces and SLOs
• Drive incident response, postmortems and engineering hygiene

Required qualifications

• 4+ years building and operating production backend systems at scale
• Strong fundamentals in data modeling (SQL and NoSQL), API design and distributed systems
• Hands-on experience with Node.js or Go in production
• Track record of owning services end-to-end: design, build, deploy, on-call
• Comfort working independently in ambiguous problem spaces with high ownership
• Solid grasp of scalability, performance and reliability trade-offs

Nice to have

• Experience building CRM, sales, pipeline or workflow products
• Worked on multi-tenant SaaS at scale (sharding, tenant isolation, fair-use limits)
• Familiarity with event streaming (Kafka, Redis Streams), queues and async processing
• Exposure to MongoDB, Postgres, ElasticSearch, ClickHouse or similar at non-trivial scale
• Have shipped a customer-facing feature backed by an LLM or similar AI API
• Frontend fluency in Vue.js
• Strong product instincts and a portfolio or GitHub of shipped work
