Job Description

Hey,

What’s the Role About?

We’re building high-scale backend systems that power smart email sequences, mailbox warmup, real-time analytics, and more all used daily by thousands of sales teams globally.
As an

SDE-2 Backend Engineer

, you won’t just write endpoints you’ll architect microservices, stream millions of events via Kafka, and optimize multi-terabyte datasets in MySQL and MongoDB. You’ll work at the intersection of scale, reliability, and product impact and own your services end-to-end.
This role is for engineers who think in systems, care about clean, reliable code, and are driven by scale, performance, and ownership.

Why Join Us?

Purpose:
You’ll own key parts of the Saleshandy backend, powering mission-critical product features and directly shaping user experience and reliability.Growth:You’ll work on high-scale systems, Kafka eventing, job queues, real-time insights, and API infra. This is the best place to grow into SDE-3 or Tech Lead roles.Motivation:If you enjoy solving architecture problems, optimizing bottlenecks, and working with high-agency engineers — this is the team you want to be on.

Your Main Goals

Design and Ship Scalable Microservices (within 60 days) Build and deploy new backend services using Node.js and clean architectural boundaries. Prioritize scalability, separation of concerns, and reusability. Goal: Ship 1–2 production-grade services used in live flows with clear ownership and on-call readiness.
Optimize MySQL and MongoDB Access Patterns (within 45 days) Fix slow queries, optimize schema design, and reduce DB load using smart indexes and query planning. Target: Improve average query latency for key endpoints by 30%+ and reduce DB CPU usage on heavy tables.
Handle Real-Time Streams Using Kafka (within 90 days) Process, partition, and consume Kafka streams reliably. Implement idempotent processing, back-pressure handling, and scale-out consumers. Outcome: Achieve >99.99% success rate on core Kafka stream with clean retry behavior and minimal lag.
Strengthen Backend Reliability and Observability (within 75 days) Improve service uptime, reduce flaky retries, and integrate robust logging/metrics using Grafana, Tempo, and Loki. Result: Cut production escalations for your services by 50%, and ensure clear dashboards and alerts are in place.

Important Tasks

First 30 Days – Service Audit & Ownership Setup Review existing backend services and take full ownership of 1–2 of them. Set up on-call readiness, alerts, and health dashboards.
Design a New Microservice From product requirement to deployment — design, implement, test, and release a new backend service with real business value.
Kafka Consumption at Scale Implement a Kafka consumer that handles 100k+ events/day with offset tracking, retries, dead-letter queue, and observability.
Solve a High-Impact DB Performance Issue Pick a slow API or query and improve it end-to-end — from EXPLAIN to caching to schema change or code refactor.
Contribute to Infra Best Practices Collaborate with SREs and infra team to improve Docker setup, deploys, or rate-limiting logic. Bonus if you eliminate flaky CI/CD issues.
AI Tooling Adoption Use Copilot or Cursor to write, test, or debug code faster such as writing unit tests for a queue processor or scaffolding boilerplate routes.
Participate in System Design Reviews Present at least one design document in engineering review showing trade-offs, performance considerations, and reasoning.

Experience Level:

3–5 years

Tech Stack:

Node.js, Kafka, MySQL, MongoDB, Redis, Docker

Culture Fit – Are You One of Us?

We don’t do “just ship it.” We do “ship fast, own the outcome, and make it scalable.” You’ll work with engineers who value clean design, measured trade-offs, and long-term thinking. We expect you to speak up, take charge, and grow fast.
If you love solving system design puzzles, own your numbers, and get a thrill when things just work you’ll feel right at home here.
