Backend Engineer (Python) - (banking/payments/crypto companies)
Talent Search PRO, San Francisco, California, United States, 94199
Target Candidates: banking/payments startups/crypto
Job Description
We’re looking for a
strong Backend / Python Engineer
to help lead the development of a complex financial product handling
real money at scale , across multiple countries.
The backend powers REST APIs used by mobile (iOS/Android) and web clients, and integrates with external services such as
crypto wallets, banking providers, payment rails, authentication, and ledgering systems . This is not a greenfield demo app—this is production software where
correctness, security, and reliability matter every day .
You’ll work closely with technical leadership to set engineering standards and build systems that are
performant, auditable, and resilient . As the platform grows, this role can naturally evolve into a
backend or broader engineering leadership position .
What You’ll Be Doing
Building and owning backend services that power web and mobile clients via REST APIs
Designing and maintaining systems for
ledgering, payments orchestration, and wallet integrations
Integrating with third-party banking, crypto, and payment service providers
Tackling real-world fintech challenges like
anti-fraud, AML flows, reconciliation, and compliance-driven edge cases
Working primarily in
Python (FastAPI)
with Postgres and Redis on AWS
Identifying performance bottlenecks and breaking out services into
Go or Rust
where it makes sense
Collaborating directly with technical founders on architecture, standards, and long-term system design
Must-Haves
Experience at
fintech, payments, banking, crypto, remittances, or lending startups
Hands-on experience with
payments, ledgering, wallets, AML, fraud, or financial orchestration systems
5+ years building and shipping backend applications using
Python, Go, or Rust
Strong backend fundamentals:
Postgres, Redis, AWS , and production operations
Experience working on
real-money financial systems , not just adjacent tooling
Comfortable owning complex backend logic end to end in a startup environment
This role strongly favors engineers who have worked
deeply inside fintech or payments products , especially in startup or scale-up environments.
Nice-to-Haves
Full-stack experience and willingness to flex beyond the backend when needed
Experience designing financial systems with
auditability and correctness
as first-class concerns
Prior exposure to
stablecoins, wallets, or crypto-native payment flows
What This Role Is (and Isn’t)
✅ A core backend role building
financial infrastructure , not just CRUD APIs
✅ High ownership and direct impact on product direction
✅ Close collaboration with technical founders
❌ Not a megacorp-only background role
❌ Not a generalist backend position without fintech/payments depth
❌ Not suitable for candidates with minimal real-world Python backend experience
Location & Work Setup
Location:
San Francisco
Work model:
In-office
Relocation:
Open to relocation (no relocation assistance provided)
Visa sponsorship:
