Senior Software Engineer - Remote

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

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

• 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.

Data & Integrations

• Integrate with OTA/partner APIs; design resilient adapters, retries, backoff, and data quality checks.
• Model data for analytics workloads; collaborate with data science on the pricing engine and evaluation loops.
• Co-drive the roadmap and architecture decisions (domain boundaries, service decomposition, buy vs build).
• Set engineering standards, review PRs, mentor teammates, and unblock delivery.
• Balance velocity with reliability, cost, and long-term maintainability.

Performance and Scalability

• Optimize data-fetching flows and caching strategies to minimize latency and network overhead.
• Identify bottlenecks in frontend or backend, propose architectural improvements, and ensure smooth scaling under high traffic.
• Collaborate with DevOps/Infrastructure teams for CI/CD, monitoring, and alerting setups; potentially work with Google Cloud, AWS, or Vercel.
• Lead engineering initiatives — work with the CTO and other senior engineers to define technical direction.
• Mentor other developers, conduct code reviews, and promote best practices in clean, testable code.
• Break down product requirements or complex technical tasks into achievable sprints, providing accurate estimates.

Frontend touchpoints (as needed)

• Contribute to Next.Js/React endpoints/components when integration or contract changes require it.

Our stack (you don't need all of it)

• TypeScript, Node.Js, NestJS
• Next.Js/React (for UI)
• Terraform (nice to have), GitHub Actions, Sentry, OpenTelemetry

Requirements

• 6+ years building production software; at least 3+ years leading/owning backend services.
• Expert in Node.Js/TypeScript and a framework such as NestJS; strong SQL and Postgres fundamentals (modeling, indexing, migrations, locks, performance).
• Hands‑on GCP experience (or AWS/Azure with willingness to adopt GCP).
• Proven SaaS chops: RBAC, JWT/OAuth, API design, multi-tenancy, background jobs, rate limiting, feature flags, A/B testing.
• Security & reliability mindset: secrets management, least-privilege IAM, auditability, SLO/SLI thinking.
• Comfortable with CI/CD, Docker, and production debugging/observability.
• Clear communicator who enjoys owning problems end‑to‑end and participating in roadmap/architecture.

Nice to have

• Experience with pricing/revenue systems or marketplace dynamics.
• Data/ML adjacent experience (evaluation pipelines, offline/online experimentation).
• Experience with data stores beyond Postgres (BigQuery, DuckDB, Elasticsearch).
• Terraform/IaC, Kubernetes, or cost‑optimization on GCP.

Why Join Walkway

• Shape the Future of Travel: Influence architecture decisions on a high-impact, AI-driven SaaS platform (we recently won an Award!)
• Collaborative Culture: Work in a supportive, innovative environment that values continuous learning and open communication
• Growth & Ownership: As a senior engineer, you’ll have the autonomy to guide projects from concept to production
