Our client builds a multi-sided fintech platform designed to serve both individual consumers and business merchants through a unified financial infrastructure. The platform is built on top of SquareFi, a licensed Banking-as-a-Service (BaaS) provider, which handles regulated financial operations including IBAN provisioning, payment rails, KYC/AML screening, and crypto asset custody.

    Requirements:
 

• Extensive experience with TypeScript and NestJS building production backend services, ideally with a modular/microservice-style codebase (feature modules, DI, decorators) rather than a monolith with no boundaries.
• Strong background in PostgreSQL and Prisma ORM — schema/migration design, indexing, and query optimization for transaction-heavy, concurrent workloads.
• Hands-on experience integrating third-party financial infrastructure providers (custody/MPC wallets, payment rails, KYC/KYB/AML vendors) via REST APIs and signed webhooks, with solid instincts for idempotency, retries, and signature verification.
• Working knowledge of fiat-crypto flows: wallet provisioning, deposits/withdrawals, address management, and multi-network asset handling.
• Practical understanding of KYC/AML processes — applicant lifecycle, review/verification states, and the recordkeeping regulated fintechs need.
• Experience designing ledger-style systems: balance calculations, transaction reconciliation, and keeping internal state consistent with external provider truth.
• Familiarity with JWT-based auth, refresh-token rotation/reuse detection, and role- or session-based access control for multi-surface products (e.g. consumer, merchant, admin).

• Comfortable with Bun (or a similarly modern Node.js runtime/package manager), Docker-based deployments, and zod/class-validator-style input validation.

   

  Responsibilities:
   

• Design and build backend services in NestJS/TypeScript spanning consumer wallets, merchant payment flows, and admin tooling behind shared auth and account lifecycle logic.
• Own integrations with custody and KYC/KYB providers end-to-end: outbound API calls, inbound webhook ingestion, signature/HMAC verification, delivery dedupe, and reconciliation against provider-reported state.
• Implement and maintain ledger-accurate deposit, withdrawal, sweep, and settlement logic across fiat and crypto rails, including fee handling and refund/retry paths.
• Build transaction reconciliation and balance-calculation logic that stays correct under concurrent writes and provider outages (snapshotting, replay-safe processing).
• Optimize PostgreSQL/Prisma access patterns and add targeted indexes as new query patterns emerge from financial reporting and transaction-history features.
• Enforce coded error handling, DTO-level input validation, and API documentation standards on every new endpoint.

What you will do

• Design and build the data-streaming service in Python.
• Implement HTTP/3 and QUIC-based client-server communication.
• Integrate with S3-compatible object storage.
• Build request prioritisation, cancellation, retries, caching, and backpressure.
• Implement token-based authentication and fine-grained access control.
• Integrate Python services with native libraries and binary data formats.
• Add metrics, tracing, load testing, and failure recovery.
• Work closely with desktop visualisation and Python/ML client teams.
• Benchmark streaming performance against download-first workflows.

What we are looking for

• Strong production experience with Python.
• Experience with asynchronous Python, task scheduling, and concurrent I/O.
• Experience building high-throughput or low-latency backend systems.
• Good understanding of networking, HTTP, TLS, and binary protocols.
• Practical knowledge of S3, MinIO, Ceph, or similar object storage.
• Experience with streaming I/O, byte-range reads, caching, and memory management.
• Strong performance-profiling and debugging skills.
• Ability to design stable interfaces between independently developed systems.

Nice to have

• Production experience with C++. 
• Experience with HTTP/3, QUIC, WebTransport, or high-performance RPC.
• Background in distributed storage, CDNs, databases, filesystems, or media streaming.
• Familiarity with scientific visualisation, HPC, simulation, or large multidimensional datasets.
• Experience with CUDA or GPU data pipelines.
• Experience with OAuth, OIDC, JWT, and capability-based access.
• Knowledge of Kubernetes and OpenTelemetry.

We are looking for a senior C++ engineer to build a high-performance service for streaming large scientific and engineering datasets.

This is not a conventional CRUD backend role. You will work on asynchronous networking, HTTP/3 and QUIC, object-storage range reads, binary data transfer, native library integration, request scheduling, and bounded-memory data pipelines.

What you will do

• Design and implement the data-streaming service in modern C++.
• Build persistent HTTP/3 and QUIC-based client-server communication.
• Stream selected regions of large datasets without downloading complete files.
• Integrate with S3-compatible object storage and native data-processing libraries.
• Implement asynchronous request scheduling, prioritisation, cancellation, retries, caching, and backpressure.
• Design stable binary and JSON interfaces between independently developed components.
• Implement token-based authentication and fine-grained access control.
• Optimise memory allocation, copying, concurrency, and end-to-end throughput.
• Add metrics, tracing, load testing, and failure recovery.
• Collaborate with visualisation, machine-learning, backend, and systems engineers.

What we are looking for

• Strong production experience with modern C++17/20.
• Experience building high-throughput, low-latency, or data-intensive systems.
• Strong understanding of asynchronous and concurrent programming.
• Good knowledge of networking, HTTP, TLS, and binary protocols.
• Experience with streaming I/O, byte-range access, buffering, caching, and memory management.
• Practical knowledge of S3, MinIO, Ceph, or similar object-storage systems.
• Strong debugging, profiling, and performance-optimisation skills.
• Experience designing reliable APIs and component boundaries.
• Familiarity with Linux systems programming and production service operation.

Nice to have

• Experience with HTTP/3, QUIC, WebTransport, or high-performance RPC.
• Experience with zero-copy or low-copy data paths.
• Experience integrating C++ libraries with Python
• Familiarity with CUDA or GPU-oriented data pipelines.
• Background in distributed storage, databases, CDNs, filesystems, media streaming, HPC, or scientific visualisation.
• Experience with OAuth, OIDC, JWT, and capability-based access.
• Knowledge of Kubernetes and OpenTelemetry.
