Invisia Software develops and operates digital products with an emphasis on dependable engineering, practical problem-solving and measurable product quality. Our teams build customer-facing applications and the services behind them, integrating external platforms and handling transaction-critical workflows.THE OPPORTUNITY
We are looking for a hands-on Backend Technical Lead to take technical ownership of the backend services that support real-time availability, reservations, third-party integrations, payments and customer-facing APIs. You will design and write production code, guide backend engineers, strengthen reliability, and turn agreed product requirements into maintainable technical solutions. This is a technical leadership role, not a purely managerial or architecture-only position.Key Responsibilities
Backend design and hands-on engineering
Design, develop and evolve services, REST APIs, data models and asynchronous workflows using Node.Js, TypeScript and AWS.Make sound technical decisions on DynamoDB access patterns, relational data, indexing, caching and queue-based processing;
document important trade-offs.Build resilient integrations with external service providers, including timeout handling, retries, rate limits, idempotency and safe failure recovery.Transaction correctness and platform reliability
Own the technical integrity of reservation and payment workflows, including state transitions, duplicate prevention, callbacks/webhooks and recoverable failure scenarios.Implement controls and support operational reconciliation for transaction status, refunds and external-system mismatches;
partner with the appropriate business and finance owners.Diagnose production issues using logs, metrics and traces;
coordinate incident response, lead technical root-cause analysis and drive preventive fixes.Set and improve practical backend service objectives with engineering and DevOps, covering latency, errors, availability, capacity and cloud efficiency.Technical delivery and team leadership
Translate approved requirements into implementation designs, estimates, technical tasks and dependencies;
raise risks early and deliver to agreed engineering commitments.Remain actively involved in development, complex debugging, design reviews and code reviews;
unblock engineers without becoming a single point of failure.Mentor backend engineers, uphold clean code and secure engineering practices, and improve unit, integration and contract testing.Work closely with Product, TPM, Web/Mobile, QA and DevOps on API contracts, releases, incident prevention and end-to-end solution quality.Own backend-level technical decisions;
align material architectural or platform changes with the designated Engineering Leader / CTO.Required Experience And Capabilities
Strong recent production experience with Node.Js and TypeScript, including personally designing and delivering complex backend services.Usually 8-12 years in backend engineering, including demonstrated technical leadership of engineers or critical services;
proven ability matters more than tenure.Practical AWS experience, especially with relevant services such as Lambda, API Gateway, DynamoDB, SQS/SNS, RDS and CloudWatch.Good command of NoSQL and SQL data modeling, query optimization, consistency, caching and event-driven design.Experience with external APIs and transaction-critical workflows;
understands idempotency, observability, failure modes and data integrity.Evidence of production troubleshooting, code quality improvements, automated testing and safe deployments.Clear technical communication, ownership of outcomes and the ability to make pragmatic decisions in a growing engineering team.GOOD TO HAVE
Experience with reservation, availability, inventory, e-commerce, marketplace or payment processing systems.Stripe, Redis, Datadog, infrastructure-as-code, CI/CD automation or comparable tooling.Experience improving a live platform incrementally while preserving service continuity.What Success Looks Like
Within the first 90 days, develop a working understanding of critical backend services, map key failure and performance risks, and deliver prioritized improvements with the team.Establish meaningful service baselines, visible engineering-quality practices and clear technical ownership for important backend components.Over time, demonstrate measurable gains in transaction reliability, incident recurrence, API performance, code quality and predictable technical delivery.SELECTION PROCESS
Introductory discussion and experience review;
practical backend system-design / debugging exercise;
deep technical discussion and code review;
leadership and collaboration interview. We focus on evidence of work personally owned and problems solved.
