Senior FullStack Software Engineer ( React and NodeJS)

Role: Staff Software Engineer (Full Stack)

Location: Dallas, TX (Hybrid role) ( REMOTE option available for the right candidate)

Note: No work visa sponsorship is available for this role.

Staff Software Engineer (Senior role) to anchor our Portal platform and Node.js/Express microservices.

Heavy hands-on TypeScript/React and Node, API design, security, MongoDB, CI/CD, and operability on Azure/Kubernetes.

You raise the bar by example, simplify designs, mentor others, and own outcomes from code to production.

About the team: Our Portal is the front door for multiple products. It’s a TypeScript/React micro-frontend environment backed by a fleet of Node.js/Express services behind an API gateway. We run containers on Azure Kubernetes, ship via GitHub Actions, use feature flags for progressive delivery, and measure what matters with OpenTelemetry plus ELK/App Insights. We validate quality with WebdriverIO/Sauce (incl. visual)

What you’ll do:

• Ship production code weekly across Portal MFEs (TypeScript/React) and Node.js/Express services.

• Design and evolve REST APIs: clear contracts, versioning, idempotency, safe rollouts, and deprecation plans.

• Improve performance end-to-end: Core Web Vitals in the browser, p95/p99 latency and throughput on services.

• Lead secure-by-default patterns: OAuth2/OIDC PKCE, service-to-service JWT, scopes, least privilege, secret hygiene.

• Make systems self-healing and self-service: health probes, autoscaling, canary and blue/green, safe rollbacks, config as code.

• Own MongoDB Atlas usage: pragmatic schema and index design, query shaping, migrations, TTL, performance diagnostics.

• Strengthen CI/CD: reusable GitHub Actions, environment protections, SBOM, CodeQL/SAST, quality gates.

• Build a resilient test strategy: unit and contract tests, reliable E2E, visual baselines, PSR gates in CI.

• Lead blameless incident reviews. Fix root causes and land durable guardrails.

• Coach engineers across time zones. Pair often, give crisp reviews, and turn hard problems into teachable moments.

• Partner with PM and Design to slice work by customer value and measure impact after release.

Tech you’ll use here • Frontend: TypeScript, React, MUI4/5, shadcn, Tailwind, Storybook, MFEs (iframe and module federation).

• Services: Node.js, Express (some Nest), REST APIs, webhooks, async jobs where it fits.

• Data: MongoDB Atlas v7→v8, schema design, indexing, migrations, some Postgres/Snowflake.

• CI/CD: GitHub Actions, environment protections, SBOM, CodeQL/SAST, automated rollbacks.

• Runtime: containers on Azure Kubernetes via an internal BY platform.

• Observability: OpenTelemetry, ELK/Kibana, Azure App Insights, actionable alerting.

• Testing: Jest/Vitest, contract testing, WebdriverIO + Sauce (E2E and visual), BlazeMeter for PSR.

• Delivery: feature flags, gradual rollouts, canary and blue/green
