Backend Developer

About the company

This is a profitable, venture-backed startup that builds a unified API for HR, payroll, ATS, and benefits systems. Instead of integrating separately with dozens of HR and payroll platforms, customers integrate once with this platform. The company supports 65+ HR and payroll systems and processes over 100,000 syncs a day. It works with established players in the HR-tech and benefits space. The business is profitable and is growing 5 to 6 times year-over-year.

What this role really is

This role is centered on Python, FastAPI, and Postgres. The backend team is small, so this is not a sub-component of a sub-component. The engineer owns integrations end-to-end. If the company signs a customer who needs a new connector, for example Paycor, the engineer builds it, writes its tests, ships it to production, and is on-call when it breaks.

Some weeks involve writing connector code. Some weeks involve debugging a race condition in the worker pool. Some weeks involve joining a call with a customer's engineering team to help them understand an integration issue. The role is wider than it sounds.

First six months, roughly

• Month 1: Onboard. Ship one small fix to production in week one. Read the codebase. Understand how connectors are tested.
• Month 2: Take ownership of the first integration, likely a payroll connector that has not yet been built.
• Month 3: Ship it to a paying customer and join the implementation call.
• Months 4 to 6: Take on two more integrations and complete the first on-call rotation. Start contributing to shared infrastructure such as the auth layer, the rate-limit handler, and the sync orchestrator.

This ramp is intentionally fast. Candidates who find it energizing rather than intimidating are the right fit.

Who you are

• You have 2 to 5 years of experience writing production Python. FastAPI experience is ideal, and candidates with Flask or Django experience who can pick up FastAPI quickly are also a good fit.
• You have experience running Postgres in production, and you understand indexes and deadlocks, and you have debugged slow queries caused by missing WHERE clauses.
• You read other people's APIs critically and have opinions on good API design, including how pagination should work.
• You write commits and pull requests that explain your reasoning, not just the changes you made.
• You are comfortable debugging unfamiliar systems. The company integrates with 65+ external APIs, many of which have poor documentation, so reading network traces and reverse-engineering undocumented behavior is a regular part of the job.

Who you are not

• You are not someone who wants a clear ticket queue and a manager assigning work, since this team expects engineers to find work and run with it.
• You are not someone who needs a perfect spec before starting. Specs exist here but are often wrong, and the expectation is to ship, learn, and revise as you go.
• You are not someone who sees integration work as less interesting engineering. Moving the right data to the right place at the right time with the right guarantees is genuinely hard and valuable engineering work.

The offer

• Cash: Cash compensation is competitive for the Indian market and is indexed to what you would expect from a well-funded mid-stage startup. The company is profitable and pays real cash compensation rather than relying mainly on equity.
• Equity: Meaningful ESOPs with a 4-year vesting schedule and a 1-year cliff.
• Location: Based in Bengaluru, HSR Layout. Relocation support is available for candidates moving cities.
• Equipment: A MacBook Pro of your choice along with any other equipment you need.
• Health: Health insurance for the employee and their dependents.

About ZYSYGY

ZYSYGY is building Germany's zero-fee payment network. Merchants pay zero transaction fees. We route payments directly over SEPA Instant, bypassing Visa, Mastercard, and the entire card network chain. No hardware. No card reader. Just a phone.

We are building the first company to combine a fully software-based merchant POS with a consumer super-app for everyday financial life: payments, transport, utilities, government services, all in one place. Think what UPI did for India. We are doing it for Germany, from the ground up, on banking rails.

Role Overview

You will join the core engineering team as a founding engineer. You will own the backend payment engine end to end: transaction flows, wallet management, SEPA Instant settlement, KYB/KYC integration, recurring mandates, refund logic, and the compliance export layer (DATEV, Kassenbuch, GoBD, fiskaltrust). On mobile, you will contribute to the React Native consumer and merchant apps alongside our mobile engineer.

You will own what you build from development through deployment, monitoring, and production reliability. The architecture decisions you make in the first six months will run in production for years.

What you will do

Design and build the backend payment engine: transaction flows, wallet management, SEPA Instant settlement, offline payment authorization, and recurring mandate billing.

Own KYB/KYC integration and the compliance export layer: DATEV, Kassenbuch, GoBD, and fiskaltrust for KassenSichV.

Build REST APIs for financial-grade reliability and high-throughput transaction processing, including full R-transaction handling and reconciliation pipelines.

Contribute to the React Native consumer and merchant mobile apps alongside our mobile engineer.

Own the full lifecycle of what you build, from development through deployment, monitoring, and continuous improvement.

Integrate AI tooling into your development workflow as a matter of course: code generation, automated testing, and intelligent review.

Who you are

Meaningful hands-on experience building payment systems, fintech infrastructure, or financial APIs.

You have designed a ledger. You understand double-entry bookkeeping, immutable transaction records, and why you never update a financial row.

You have solved the partial failure. Money left one wallet and did not arrive in the other. You know how to detect it, resolve it, and make sure it does not happen again.

You understand idempotency at a design level. You have built systems that survive client retries, duplicate webhooks, and network drops without double-charging anyone.

You have built or reasoned about reconciliation: detecting discrepancies between your internal ledger and an external settlement file, and resolving them reliably at scale.

You understand KYC and KYB state machines, what happens when verification status changes mid-transaction, and what a regulator expects from your audit trail.

You are comfortable with SQL databases and own the full lifecycle of your code from development through deployment.

You can communicate technical decisions clearly to non-technical stakeholders. At this stage of the company, that matters.

You are a continuous learner. Payments infrastructure is a deep domain and you treat it that way.

You are comfortable with ambiguity and early-stage risk. There is no playbook yet. You will help write it.

Strong academic background preferred. Demonstrated engineering ability matters more than institution.

Relocation

Relocation to Munich, Germany, is on the table for the right candidate, including visa support.
