Lead Software Engineer

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.

Compensation & benefits

• Competitive salary + equity

• Medical, dental, vision
  • 401(k)

• Learning budget (including AI tools and cloud certifications)
