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 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, monitor, and alerting set‑ups;
  potentially work with , 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.

If you’re based in Europe, North America, or Latin America, don’t hesitate to reach out!
