WHAT YOU WILL OWN

- Design and maintain Python/FastAPI APIs and PostgreSQL schemas, queries and migrations.

- Build and operate subscriptions, payment integrations, webhooks and background jobs.
- Implement authentication, permissions, secure coding and data protection.
- Diagnose production failures using logs and monitoring; improve performance and prevent repeat incidents.
- Make practical architecture decisions for growing traffic and maintainable services, working with product and cloud engineers.

ESSENTIAL EXPERIENCE

- At least 3 years of professional backend engineering, with personal ownership of a live service used by real users.
- Strong hands-on Python, FastAPI, PostgreSQL and API design skills.




- Experience with subscriptions/payments, background processing, third-party integrations and reliable data syncing.
- Experience diagnosing production incidents and improving database or API performance under real workloads.
- Ability to explain your individual contribution, technical trade-offs and measurable outcomes.
- Availability for full-time, on-site work in Chennai six days a week.

WHAT TO INCLUDE WITH YOUR APPLICATION

Apply through LinkedIn and attach your resume. Include a short production-project summary in your resume or an attached document covering:

- A live product or backend you personally built or operated, with a public link if available.
- Your exact ownership, stack, time in production and approximate users, request volume or workload.
- One production incident you resolved: cause, your fix and how you prevented recurrence.
- Your notice period, expected annual CTC and willingness to work on-site in Chennai.

Public GitHub or technical writing is welcome but not required. Redacted examples and approximate ranges are acceptable; never share confidential code, credentials or user data. Coursework and personal projects alone do not meet this role's production-experience requirement.

SELECTION PROCESS

Resume and production-evidence review, followed by a technical discussion on duplicate logs, failed syncs, PostgreSQL performance, payment reliability and traffic spikes, then a final role-fit discussion. We assess demonstrated engineering judgement and ownership.
