Solvd Inc. is a rapidly growing AI-native consulting and technology services firm delivering enterprise transformation across cloud, data, software engineering, and artificial intelligence. We work with industry-leading organizations to design, build, and operationalize technology solutions that drive measurable business outcomes.
Following the acquisition of Tooploox, a premier AI and product development company, Solvd now offers true end-to-end delivery—from strategic advisory and solution design to custom AI development and enterprise-scale implementation. Our capability centers combine deep technical expertise, proven delivery methodologies, and sector-specific knowledge to address complex business challenges quickly and effectively.
We are seeking a hands-on Tech Lead who will drive the design, implementation, and delivery of backend services and database-driven insurance allocation engines - while also contributing on the full-stack when needed. The ideal candidate is backend-strong (Node.js + PostgreSQL/MongoDB) with the ability to guide engineers across the stack (React/TypeScript).
The candidate will work closely with an existing Solution Architect (who owns target architecture and high-level design) while taking ownership of engineering execution, code quality, sprint delivery, mentoring, and day-to-day technical decisions. The systems you help build must be scalable, auditable, and transparent, powering complex, multi-tier insurance allocation logic used by enterprise clients.
What you'll do
Leadership & Delivery

- Develop multi-tier allocation and rating logic using SQL and PL/pgSQL stored procedures.
- Design schemas, indexing, and data pipelines optimized for performance, scale, and auditability.
- Conduct execution plan analysis, query tuning, and partitioning for large insurance datasets.
- Ensure deterministic, traceable, and versioned business logic.
- Support UI integration and occasionally contribute to React + TypeScript front-end components.
- Collaborate on API-driven UX workflows, contract changes, and end-to-end feature delivery.
- Implement automated tests (backend + DB logic), enforce code quality, and uphold CI/CD standards.
- Improve logging, monitoring, metrics, and alerting to ensure production readiness and transparency.
- Participate in production support, root cause analysis, and continuous improvement.
- Expert-level Node.js (TypeScript) with experience in Express/NestJS.
- Strong expertise with PostgreSQL (PL/pgSQL, query tuning, indexing, performance).
- Experience with MongoDB as a supporting data store.
- Proven experience leading engineering teams and driving delivery in a Tech Lead / Lead Engineer capacity.
- Strong understanding of REST API design, distributed systems, and backend scalability.
- Familiarity with React + TypeScript and ability to contribute meaningfully on the front end.
- Excellent communication and stakeholder collaboration skills.
- Strong testing mindset and experience with CI/CD pipelines.
- Insurance, fintech, or actuarial systems experience.
- Experience with Databricks.
- Experience with AWS/Azure, Docker, and observability stacks.
- Backend: Node.js, TypeScript, NestJS
- Databases: PostgreSQL (primary), MongoDB (secondary)
- Frontend: React, TypeScript
- Tooling: Docker, GitHub Actions, monitoring/logging stack, CI/CD
- APIs: REST (WebSockets optional)
- Shape real-world AI-driven projects across key industries, working with clients from startup innovation to enterprise transformation.
- Be part of a global team with equal opportunities for collaboration across continents and cultures.
- Thrive in an inclusive environment that prioritizes continuous learning, innovation, and ethical AI standards.
