Senior Software Engineer — .NET & Python

About Salvone

Role Purpose

Application development (.NET & Python)

• Extend and maintain existing C#/.NET applications, features, refactoring, bug-fixing, and performance work.
• Design and build new services, background workers, and REST APIs across the estate (ASP.NET Core, Web API).
• Build and maintain Python services, automation, and data/integration pipelines (FastAPI, Flask, or similar where appropriate).
• Own database design and performance across SQL Server and/or PostgreSQL/MySQL — schema, queries, indexing, and tuning.

Integration

• Design and build integrations between our applications and the wider ecosystem — ERP (Odoo), attendance, payroll, clinical, and BI systems — via REST, webhooks, queues, and scheduled workers.
• Build APIs with proper authentication, authorisation, versioning, and error handling.
• Read, debug, and integrate against third-party API documentation.
• Production ownership
• Own production quality: performance tuning, root-cause analysis, monitoring, logging, security hardening, and incident response.
• Deploy and operate applications on Linux and cloud (AWS), end-to-end.
• “I built it, I run it” — you own what you ship.
• Engineering standards
• Define and enforce Git workflows, branching, code review, CI/CD, testing, and documentation.
• Translate business and clinical requirements into technical designs.
• Mentor other developers and raise the bar across the team.

Essential Skills & Experience

• 5+ years of professional software engineering.
• Strong C#/.NET: modern .NET (Core / .NET 6+), ASP.NET Core, Web API, and Entity Framework.
• Strong Python: OOP, clean code, and at least one web/service framework (FastAPI, Flask, or Django).
• Database expertise in SQL Server and/or PostgreSQL/MySQL — schema design, query optimisation, and indexing.
• REST API design with authentication, authorisation, versioning, and error handling; webhooks, async jobs, and queues.
• Git and mature version-control workflows (branching, code review, CI/CD).
• Strong Linux fundamentals: shell, systemd, logs, processes, networking basics, reverse proxies (nginx / Apache), and TLS.
• Hands-on with at least one major cloud provider (AWS preferred): compute, storage, networking, IAM, and basic security hygiene.
• Security-first mindset: OWASP basics, least privilege, and secure handling of PII and clinical data.
• Clear written and verbal English; able to work independently and drive delivery end-to-end.

Strongly Preferred

• Healthcare domain experience — ideally UK healthcare (NHS, CQC, care homes, hospitals, or similar).
• Experience with clinical or care-sector systems: rostering, workforce/attendance, EPR/EMR, care planning, or invoicing platforms.
• Healthcare data standards: HL7 v2.x (ADT, ORM, ORU messages, MLLP transport) and FHIR (resources, REST API, profiles, Bundles).
• Understanding of UK healthcare compliance — UK GDPR, DSPT, NHS DCB standards, and CQC.
• Nice to Have
• Frontend experience: React, Angular, or TypeScript.
• Docker and containerised deployments; experience with Docker Compose.
• Infrastructure as Code (Terraform, CloudFormation) and CI/CD pipelines (GitHub Actions, Azure DevOps, GitLab CI).
• Message brokers (RabbitMQ, Redis Streams, Kafka) and async / event-driven patterns.
• Observability and monitoring tooling (Grafana, Prometheus, CloudWatch, ELK).
• Exposure to ERP / Odoo or accounting and payroll integrations (Sage, Xero, HMRC RTI).
• Identity and SSO (SAML, OIDC, Entra ID).
• Experience mentoring or leading small engineering teams.
• What Success Looks Like in the First 6 Months
• Ramped up on our .NET application estate and the surrounding integrations.
• Owning the roadmap and production quality of at least one of our applications.
• Shipped meaningful features or services to production.
• Established and enforced engineering standards (Git workflow, code review, CI/CD, testing) across the team.
• A trusted technical partner to the Technical Functional Lead and the wider business.

What We Offer

• Exposure to a broad technology stack — C#/.NET, Python, SQL, AWS, Linux, healthcare integrations, and BI.
• A lean, technical team where your work visibly moves the business forward.
• Opportunities to grow into technical leadership.
