Practice by Numbers · Gurugram, India · In-office (5 days) · Full-time

Practice by Numbers builds the software dental practices run their day on — scheduling, patient communications, analytics, VOIP and payments, in one platform. Around 1,500 practices across the US and Canada use us to run their front desk.

Payments is one of our fastest-growing areas, and one of the few where the software is directly responsible for whether a practice gets paid. We're investing heavily in it: new payment methods, new products built on the payments platform, and a lot of work making the core more reliable as volume grows.

We operate like a startup, because we are one. Scope is wide, decisions are fast, and there isn't a layer of people between you and the problem.

About the Role

~1 min read

We're hiring a software engineer for our Payments team in Gurugram. You'll report to our Payments engineering lead and work alongside senior engineers who've built this platform.

This is a good role for someone a few years into their career who wants to go deep rather than wide. Payments is an unusually good domain to grow in — correctness matters, edge cases are real, and the habits you build here (thinking about failure modes, retries, reconciliation, data integrity) transfer everywhere. It's hard to pick that up on a CRUD product, and it compounds fast once you have it.

You'll start with well-scoped work and a lot of review, and take on larger and more ambiguous pieces as you get your footing. We'd expect you to be owning a meaningful surface of the product within your first year.

Backend features and APIs in Python/Django — shipping real functionality that practices use the same week.
Payment flows. Card transactions through in-office terminals, hosted payment pages, and patient-facing payment links. You'll learn how each one fails, which is most of the education.
Recurring billing. Scheduled charges, retry behaviour, and the handling around payments that don't go through the first time.
Integrations. Working against our payment processor's APIs and syncing data into third-party practice management systems.
Queries and data. Writing and tuning PostgreSQL queries, designing tables, writing migrations that are safe to run against production data.
Bugs and production issues. A real share of them, because debugging someone else's payment edge case is how you learn a payments system properly.
Tests and tooling. Contributing to our test coverage and CI pipelines rather than treating them as someone else's job.

3–5 years building backend software professionally, with solid Python experience. Django specifically is a strong plus, but we'll take a good engineer from another framework who wants to learn it.
Comfortable with SQL and relational databases — you can write a join, read a query plan, and reason about what an index is doing.
Experience building or consuming REST APIs.
Familiarity with Git-based workflows — branching, code review, CI.
Care about correctness. In payments, "mostly working" is a bug. We're looking for someone who tests their own work and thinks about what happens when things fail, not just when they succeed.
Clear written communication. Our team spans the US, India and Bangladesh, so a lot of thinking happens in writing.

We care more about how you think than about your exact checklist of technologies. If you're strong on fundamentals and missing a couple of items above, apply anyway and tell us what you'd need to pick up.
