Senior Software Engineer

About Walkway

Walkway is on a mission to revolutionize the tours and activities industry with AI-driven revenue intelligence. We empower operators with data-rich insights, competitive benchmarking, and dynamic pricing solutions to help them stay ahead in a rapidly evolving travel landscape. As a Senior Software Engineer, you'll play a pivotal role in building and enhancing our data-intensive SaaS platform, delivering real-time analytics, automated pricing recommendations, and seamless user experiences.

About the Role

Please note that we're a US-based company, so this position will be under a contractor agreement.

We're hiring a Senior Software Engineer with a strong backend focus who can still navigate the full stack when needed. You'll own core services (pricing, data ingestion, auth / permissions), shape our architecture, and partner with the founders on roadmap and trade-offs. This role is ideal for a self-starter who enjoys moving from design → code → production and can lead by example.

Beyond coding, you'll drive engineering initiatives, collaborate with co-founders, product and data teams, and support other developers. You'll ensure our application remains performant and scalable as we handle large data sets, complex filtering logic, and real-time updates for customers.

What You'll Do

1. Backend & Platform

• Design and implement services in Node.js / NestJS (TypeScript) running on GCP (Cloud Run, Cloud SQL / Postgres, Pub / Sub, Cloud Storage, VPC).
• Build and evolve multi-tenant SaaS primitives : RBAC, org / workspace models, JWT / OAuth auth flows, API keys, rate-limiting.
• Ship reliable REST (and / or GraphQL) APIs with versioning, pagination, idempotency, and strong contracts.
• Build background workers & schedulers for pricing jobs, data ingestion, and sync tasks (Pub / Sub / queues, cron).
• Performance engineering : caching strategies (e.g., Redis), query optimization, profiling, hot-path tuning.
• Observability : metrics, tracing, structured logs (OpenTelemetry, Cloud Logging / Monitoring, Sentry).
• Secure by default : least-privilege IAM, secrets management, encryption in transit / at rest, audit trails, PII handling, SOC2-friendly habits.

2. Data & Integrations

3. Architecture & Leadership

4. Performance and Scalability

5. Team Leadership & Collaboration

6. Frontend touchpoints (as needed)
