Job Description

Saleshandy - New Product Team | Build from Zero | Own What You Ship

Experience Level:

3-5 years

Core Focus:

Distributed backend systems, job queues, infra observability, production readiness

Tech Stack:

Node.js, MySQL, Redis, Kafka, Grafana/Prometheus, AWS

Bonus:

ClickHouse, Elasticsearch, Docker

Context:

Join the founding backend team building a new AI-powered product at Saleshandy. You'll shape systems from the ground up from architecture to API design, job schedulers to observability.

What's the Role About

This isn't just another backend role, this is your shot to build a product from scratch. You'll join a small team launching a brand-new SaaS product, where you'll own everything backend: queues, databases, infra, performance, and uptime. You'll ship weekly, make tradeoffs, debug live, and influence both product and architecture without red tape or layers of approvals.

Why Join Us

Purpose: You're not patching old code, you're laying the foundation for a new system that will be used by thousands.

Growth: You'll own entire domains fast. From system design to metrics to scaling you'll learn by doing, not waiting.

Motivation: If you've ever said, "I wish I could own something end-to-end, build cleanly, and move fast without BS," this is it. You will own the backend.

Your Main Goals

1. Build and Launch a Core Feature (within 30-45 days)

Lead the development of a key backend module, a job scheduler, email engine, enrichment flow, or core DB model.

Outcome: In prod, with logging, alerting, and rollback plan.

2. Optimize Latency for High-Throughput Workloads (within 60 days)

Own and improve performance across job processors or APIs.

Outcome: 40% drop in P95 or P99 latency.

3. Stand Up Observability and Alerts (within 60-90 days)

Set up Grafana/Prometheus dashboards and actionable alerts for one major backend component.

Outcome: Issue visibility before incidents.

4. Own and Stabilize a Domain (within 90 days)

Take ownership of a system (e.g., outbound queue, webhook processor), make it reliable, and evolve it.

Outcome: 99.99% uptime, clean ownership.

Important Tasks

1. Design and build scalable backend services in Node.js

2. Implement job workers with retries, rate limits, and deduplication

3. Model relational data with MySQL and high-throughput writes

4. Set up metrics and logs using Grafana, Prometheus, and tracing tools

5. Debug production issues quickly using logs, traces, and infra metrics

6. Collaborate directly with product/design for fast feedback loops

7. Contribute to internal playbooks, code patterns, and architecture

Culture Fit - Are You One of Us

1. You ship small, frequent, production-ready PRs

2. You write down ideas, edge cases, and fixes

3. You unblock yourself with logs before asking for help

4. You question vague specs early, then execute fully

5. You treat the backend like a product clean, tested, observable
