Lead Software Engineer

Job Information :

Lead Software Engineer (.NET / AWS) - Healthcare (HIPAA)

Computrition - Jonas Software (https : / / www.computrition.com / )

Location : Remote (US) or Hybrid

Team : Engineering

Type : Full-time

Reports to : Senior Director of Engineering

Partners with : Lead Software Architect

About the role

Computrition is building a cloud-native platform for hospitals and health systems. You'll be the hands-on technical lead partnering with our Lead Software Architect to design and ship a secure, scalable .NET solution on AWS with a React front end, a .NET business / API layer, and PostgreSQL for persistent data. You'll own critical services, mentor engineers, raise the bar on engineering practices, and help us leverage AI safely to deliver high-quality software faster.

Attention on backend - business and API layer.

What you'll do

Design & build : Lead development of distributed services in .NET 8 / C# (ASP.NET Core), including REST / gRPC APIs, background workers, and event-driven components.

Cloud architecture : Implement cloud-native patterns on AWS (e.g., ECS / EKS / Lambda, API Gateway, RDS / Aurora PostgreSQL, S3, SQS / SNS / EventBridge, CloudWatch, KMS, Secrets Manager, Cognito / SSO).

Data & performance : Model schemas in PostgreSQL , optimize queries / indices, tune performance, and design migrations and data retention strategies.

Security & compliance : Build with HIPAA in mind-least-privilege IAM, encryption in transit / at rest, audit logging, PHI data handling, BAA considerations, and secure SDLC practices.

Quality & delivery : Champion CI / CD (GitHub Actions / CodeBuild / CodePipeline), IaC (Terraform / CDK / CloudFormation), automated testing (unit / integration / contract), and safe feature-flag rollouts.

Observability : Establish metrics, logs, and traces (OpenTelemetry) with actionable dashboards and alerting; lead incident response and postmortems.

Technical leadership : Run design reviews, set coding standards, perform thoughtful code reviews, and mentor a small team of engineers.

AI First Mentality : Safely apply AI tools (code assistants, test generation, static analysis, documentation) to accelerate delivery-respecting PHI boundaries and vendor policies.

Collaboration : Work closely with Product, Security / Compliance, Customer Success, and clinician stakeholders to translate needs into resilient designs.

Our stack

Backend : .NET 8 (C#), ASP.NET Core (REST / gRPC), EF Core / Dapper, MediatR / CQRS where it fits

Frontend : React (TypeScript), Fluent UI , Vite / Webpack, Jest, React Testing Library

Data : PostgreSQL, Redis, S3 (cold storage); potential Redshift / Athena for analytics

Infra / DevEx : AWS, Docker, Terraform or CDK, GitHub Actions, OpenTelemetry, Grafana / CloudWatch

Clean Code, Architecture & Design Patterns

We hold a high bar for clarity, maintainability, and long-term agility.

Principles we practice

SOLID , DRY , KISS , YAGNI -favor simple, composable solutions over cleverness.

Clean Architecture / Hexagonal boundaries : keep the domain independent of frameworks; depend on abstractions; isolate external concerns (DB, AWS, UI) behind ports / adapters.

Secure-by-design : least-privilege IAM, safe handling of secrets, auditability, and privacy-by-default patterns appropriate for HIPAA.

Coding standards

Small, focused classes / functions with intention-revealing names; avoid primitive obsession and Law-of-Demeter violations.

Prefer immutability and pure functions where practical; inject dependencies; avoid shared mutable state.

Consistent formatting (EditorConfig, dotnet format) and analyzers (Roslyn / Sonar) enforced in CI.

Design patterns (used judiciously)

Creational : Factory, Builder for complex object construction.

Structural : Adapter, Facade, Decorator to compose behavior without inheritance.

Behavioral : Strategy, Command, Observer, Mediator (e.g., MediatR) to decouple flows.

Architectural : CQRS where it adds value; domain events; anti-corruption layers between bounded contexts.

Cloud / resilience : Circuit Breaker, Retry, Timeout, Bulkhead (e.g., Polly); Outbox pattern and idempotency for message-driven workflows; Saga / Process Manager for long-running, multi-service transactions.

Performance : Cache-aside (Redis), pagination / streaming, backpressure for event consumers.

Testing & quality

Pragmatic TDD / test-first when it reduces risk; comprehensive unit, integration, and contract tests; UI component tests (React Testing Library / Jest).

Observability baked in : structured logs, metrics, traces (OpenTelemetry) with actionable SLOs.

Security and quality gates in CI (SAST / DAST, dependency scanning, secrets scanning).

Architecture Decision Records (ADRs) and short RFCs for significant changes.

What this looks like day-to-day

Write code a teammate can extend in 6 months without a meeting.

Choose patterns intentionally-explain trade-offs, avoid over-engineering, and delete complexity when it no longer pays for itself.

Use AI assistants responsibly (no PHI) for rote tasks-tests, boilerplate, refactor suggestions-while you own the design thinking.

What success looks like (first 6-12 months)

Ship a HIPAA-ready MVP service to production with SLOs and dashboards.

Reduce lead time for changes and MTTR through CI / CD, testing, and on-call hygiene.

Establish engineering patterns (service templates, linting, PR workflows) that the team loves to use.

Demonstrate practical AI use that measurably cuts cycle time without risking PHI.

Required qualifications

7+ years building production systems; 3+ years in a lead role.

Expert in .NET / C# and ASP.NET Core for high-throughput, cloud-hosted services.

Strong AWS experience designing secure, cost-efficient architectures.

Solid PostgreSQL skills : schema design, performance tuning, migrations.

Hands-on with CI / CD and IaC (GitHub Actions, Terraform / CDK, Docker).

Proven ownership of production systems (incident response, postmortems).

Working knowledge of HIPAA concepts (PHI handling, auditability, BAAs, and logging).

Excellent communication : clear design docs, pragmatic trade-offs, and stakeholder alignment. Ability to speak up and express opinions or concerns in a positive and constructive manner.

Proven use of AI coding assistants, prompt engineering for dev workflows, or internal guardrails for safe AI usage.

Nice to have

Experience in hospital / health-tech, HITRUST / SOC 2, and secure SDLC tooling.

Event-driven architectures (SQS / SNS / EventBridge), gRPC, and background processing.

Frontend performance / accessibility expertise and design systems experience.

Observability at scale (log aggregation, tracing, SLO / SLA design).

Data warehousing / ELT exposure; analytics in regulated environments.

Soft skills we value

Product mindset : You empathize with clinicians and hospital workflows and sweat usability and reliability.

Technologist spirit : Passionate about new technologies; you evaluate tools critically and adopt them when they add real value.

AI-savvy pragmatism : You thoughtfully leverage AI to speed coding / testing / docs, and you know when not to.

Bias for action : You ship iteratively, automate the boring parts, and leave systems better than you found them.

Leadership & mentorship : You elevate teammates through pairing, feedback, and clear guidance.

Ownership & accountability : You take responsibility end-to-end-from design to run-time.

Communication : You write crisp RFCs, explain trade-offs simply, and collaborate across functions.
