Software Development Engineer III (CRM - Opportunities)

We are seeking an SDE-3 Backend Builder to own the CRM Opportunities product end-to-end. Opportunities is the deal and pipeline engine at the heart of our CRM — the system of record for every revenue motion our customers run, from lead conversion to closed-won.

This role emphasises deep backend ownership: designing data models, APIs, and distributed workflows that power pipelines, stages, automations, reporting, and integrations at scale. You will operate with high autonomy, turning ambiguous problems into production systems, with enough frontend fluency to ship the occasional UI surface without waiting on anyone.

Own the full lifecycle of Opportunities backend: translate business and customer needs into scalable, production-grade services

Design and evolve the data model for pipelines, stages, deals, and associated entities — getting consistency, throughput, and query patterns right

Build and scale APIs, event-driven workflows, and background jobs that handle high-volume writes, automations, and integrations

Tackle distributed systems concerns: idempotency, eventual consistency, race conditions, hot tenants, and noisy-neighbor isolation

Improve performance and reliability of large pipelines (millions of opportunities per workspace) through indexing, sharding, caching, and query optimization

Ship end-to-end when needed — including UI changes in Vue — without blocking on cross-functional handoffs

Instrument the system: logs, metrics, traces, and SLOs that make production behavior legible
Drive incident response, postmortems, and the engineering hygiene that keeps a high-traffic product healthy

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

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

Frontend fluency in Vue.js — enough to ship a feature without a frontend partner
Strong product instincts and a portfolio or GitHub of shipped work

Ships Opportunities features from idea to production with minimal cycle time

Builds services that stay reliable as workspaces grow from thousands to millions of deals

Makes sound trade-offs between speed, quality, and long-term maintainability

Raises the bar on data correctness, API design, and operational excellence for the product
Continuously sharpens the customer experience through iteration and instrumentation
