Java Developer – Job Description

We are seeking a Senior Backend Developer with strong expertise in Java (Spring Boot) and working knowledge of Python. In this role, Java will be your primary development language, with Python used for scripting, automation, or selected service modules. You’ll be part of a collaborative backend team building scalable and high-performance systems.

Key Responsibilities

• Design and develop robust backend services and APIs primarily using Java (Spring Boot)
• Contribute to Python-based components where needed for automation, scripting, or lightweight services
• Build, integrate, and optimize RESTful APIs and microservices
• Work with relational and NoSQL databases
• Write unit and integration tests (JUnit, PyTest)
• Collaborate closely with DevOps, QA, and product teams
• Participate in architecture reviews and design discussions
• Help maintain code quality, organization, and automation

Required Skills & Qualifications

• 4 to 10 years of hands-on Java development experience
• Strong experience with Spring Boot, JPA/Hibernate, and REST APIs
• At least 1–2 years of hands-on experience with Python (e.g., for scripting, automation, or small services)
• Familiarity with Python frameworks like Flask or FastAPI is a plus
• Experience with SQL/NoSQL databases (e.g., PostgreSQL, MongoDB)
• Good understanding of OOP, design patterns, and software engineering best practices
• Familiarity with Docker, Git, and CI/CD pipelines

Why this role exists:

You’ll own our data pipelines—ingesting, cleaning, and serving fashion/e-commerce data at scale—so the team (and founder) can focus on building new capabilities. If you love end-to-end ownership and turning messy web data into reliable, queryable systems, this role is your playground.

What you’ll do:

• Ingestion at scale: Design, build, and operate resilient crawlers/scrapers with rotation, rate-limits, backoff, and change-tolerance.
• Robust pipelines: Normalization, deduping, schema evolution, enrichment, and SLAs for freshness & completeness.
• Data stores & caching: Model products/variants/attributes in PostgreSQL, manage Redis for caching/queues, and keep costs predictable.
• Observability & quality: Instrument with metrics/tracing, add data QA checks, alerts, and auto-healing where sensible.
• Performance & reliability: Optimize throughput, memory, I/O, and infra spend; design for retries, idempotency, and correct delivery semantics.
• Collaboration: Partner with search/ML/product teams; write crisp docs; raise the bar in reviews; mentor where helpful.

Must-haves:

• Super high ownership: End-to-end closure on tasks you lead.
• 3.5+ years building backend systems, preferably in Python with production ownership.
• Strong data pipeline experience (batch/stream): schema design, deduplication, and backfills.
• Hands-on with PostgreSQL/MySQL and Redis (caching, rate-limits, queues).
• Real-world web scraping: requests/httpx/aiohttp, BeautifulSoup/lxml/Scrapy/Playwright, anti-bot tactics, respectful crawling.
• Concurrency & async (asyncio, multiprocessing), robust error handling, idempotent jobs.
• Solid testing habits and bias for simple, maintainable code.

Nice-to-haves:

• Message queues/streams: Kafka, RabbitMQ, SQS.
• Workflow schedulers: Airflow, Prefect.
• GraphQL; search tech (Elasticsearch/OpenSearch).
• Cost/perf tuning, on-call pragmatism, or prior startup/founding team experience.

How we work:

• High ownership, fast shipping, clear interfaces, strong documentation.
• We optimize for time to go live—startups that succeed outpace those that don’t.
• Competitive salary + meaningful ESOPs.
• (Optional) Work from our hacker-house on MG Road, Gurgaon.

Hiring process (fast closures)

1. 30-min technical deep-dive
2. Take-home (optional)
3. Founder conversation & references
