Job description

Senior Software Engineer (TypeScript, Python)

Project Overview

We are seeking a Senior Software Engineer to join our HealthTech product teams building SaaS solutions for the US pharmaceutical market, including Patient Onboarding, REMS Administration, and Wholesale Distribution.
This role consists of two sequential phases:
Phase 1 (approx. 2-3 months) - Data Processing Platform. You will work on a Python-based data processing platform handling pharmaceutical transaction pipelines: SFTP file ingestion, EDI 270/271 transaction processing, business rule execution, and client-specific file output generation. The work focuses on adapting existing services to new client requirements.
Phase 2 - Full-Stack Healthcare Platform. You will transition to a full-stack healthcare platform built with React, NestJS, Prisma, and an Nx monorepo on Microsoft Azure. This is a long-term engagement covering patient and provider portals, case management, and clinical data integration.
You will work closely with US-based stakeholders, so excellent English and strong communication skills are essential. We highly value engineers who stay on top of modern development trends and use tools like Cursor, Claude Code, VS Code with Copilot, and other AI-enhanced environments.

Technical Details:

Phase 2 - Full-Stack Healthcare Platform:
Front-End: React, TypeScript, Tailwind CSS, shadcn/ui, Radix UI, Vite, Nx
State & Data: Redux Toolkit, TanStack React Query, React Hook Form, Zod
Back-End: NestJS, TypeScript, Prisma ORM, PostgreSQL, Redis, Bull
Auth: Microsoft Entra External ID, FHIR SMART, Permify (RBAC + ReBAC + ABAC)
Healthcare: HAPI FHIR Server (R4)
Case Management: Flowable
Azure Services: App Services, Container Apps, Functions, APIM, Service Bus, Blob Storage, Communication Services
Testing: Vitest, Jest, Playwright
We follow the principle of right tools in right places - our stack is broad because each technology serves a specific purpose in the platform.

Responsibilities

Phase 1

• Extend and adapt data processing pipelines for new client integrations
• Implement business rules for EDI 270/271 transactions and file transformations
• Write clean, strictly-typed Python with Pydantic models and comprehensive test coverage

• Maintain high pipline performance

Phase 2

• Build and maintain features across the React front-end and NestJS APIs within the Nx monorepo
• Take ownership of assigned system components, making architectural decisions within their scope
• Collaborate with other component owners to ensure consistency and alignment across the platform
• Design and optimize PostgreSQL schemas, manage migrations, and ensure data integrity
• Integrate Azure services as needed for your components (App Services, Container Apps, Functions, APIM, Key Vault)

What Keeps Us Sharp and Steady

We cut the fluff and keep it real—owning our work, refining our craft, and always leveling up. No excuses, just a team that’s in it together, pushing boundaries and delivering results.

Pragmatic

Theory’s cute, but results pay the bills. Perfect’s a fairy tale—done right is what counts.

Adult

No drama, no sugarcoating. We own our wins and our screw-ups, and treat failure like free tuition.

Craftspeople

We’re not assembly-line coders. We build, we refine, and we don’t put a fresh coat of paint on bad code.

Falling behind? We leave that to others. Leveling up fast, chasing down answers, and never settling for “I don’t know.”

Great Allies

No lone wolves here. We listen before we talk, communicate like grown‑ups, and make the ride better for everyone.
