LTi Technology Solutions is a leading provider of asset finance and leasing software, purpose-built for the financial services industry. Our flagship platform, Aspire, powers the full asset finance lifecycle, from origination and credit decisioning through portfolio management, billing, accounting, and end-of-term; for banks, captives, independent finance companies, and specialty lenders across North America and internationally.
Backed by private equity and in active growth mode, LTi is making the most significant platform investment in the company's history: a ground-up re-platform of Aspire onto a modern .NET and React architecture running on Microsoft Azure. Our customers manage billions of dollars in lease and loan portfolios on Aspire, and the next generation of the product will carry that mission-critical workload forward on a foundation built for scale, extensibility, and speed of delivery.
This is a rare opportunity to join a profitable, established software company at an inflection point, where foundational engineering investment will directly shape product strategy, customer outcomes, and competitive differentiation.
LTi is hiring a Senior Software Engineer to build the user experience of the next-generation Aspire platform. This is a full-stack role weighted toward the front end: roughly two thirds of the work is React and TypeScript, and the balance is the .NET services and APIs that sit behind it. Enterprise asset finance software lives or dies on dense, data-heavy screens, so the product surface you build is a primary reason customers choose Aspire over the alternative.
Reporting to the VP of Engineering, this role works within a talented team of senior level developers to build out our next generation product and platform. This is an individual contributor role without direct reports.
The work is greenfield, which means fewer constraints and more ambiguity than most product development roles. The ideal candidate is comfortable owning a feature end to end, from the API contract through the interaction design, and cares about the quality of the interface itself rather than treating it as the layer that renders the data.
Front-End Engineering (React & TypeScript)
-
Build production features in React and TypeScript across the next-generation Aspire application, applying the project structure, routing, state management, and data-fetching patterns established for the platform
-
Build the data-heavy interaction patterns that define asset finance software, including high-volume virtualized grids, complex multi-step workflows, configurable forms, and embedded reporting and analytics surfaces
-
Own client-side performance in a large enterprise application, including rendering behavior under real portfolio volumes, memoization, virtualization, code splitting, and bundle discipline
-
Handle real-world failure gracefully, defining loading, empty, error, and partial-data states so the experience degrades predictably rather than breaking
Design System & Component Library
-
Build and extend a shared component library and design system foundation in partnership with product design and the engineering team, including theming, tokens, and documentation in Storybook or equivalent
-
Hold the line on visual and interaction consistency across a large application, resolving one-off component requests into reusable patterns rather than accumulating variants
-
Build to accessibility standards rather than retrofitting for them, including keyboard navigation, focus management, and screen reader behavior in complex composite controls
Full-Stack Delivery (.NET & API)
-
Build the backend services and endpoints your features depend on in modern .NET, working within the domain model and bounded contexts defined for the platform
-
Shape API contracts from the consumer side, contributing to the resource modeling, pagination, filtering, and error semantics that make LTi's Aspire API 2.0 standards consistent, predictable, and guessable
-
Own features end to end, from data access and service logic through the interface, rather than handing off at the API boundary
-
Learn the asset finance domain in depth, including contracts, assets, lessees, payment schedules, billing, and accounting, so the interfaces you build reflect how customers actually work
Quality & Craft
-
Write and maintain meaningful tests at the right level, including unit tests, component tests with React Testing Library, and end-to-end coverage in Playwright or Cypress for the workflows that matter most
-
Participate in code review and design discussion as a contributor of judgment, not just approval, and help evolve the standards as the team learns what works
-
Partner with the team’s Platform Engineer on front-end build, deployment, and observability so that quality signals reach the team before customers do
-
Use LTi's AI-assisted development practices effectively and safely, including spec-driven development workflows and the existing Claude Code environment
Front-End & React
-
Strong proficiency in React and TypeScript, including modern hooks-based patterns, component composition, and type-safe interfaces across an application of meaningful size
-
Practical experience with server-state libraries (TanStack Query or equivalent), client state management, and form libraries in complex enterprise applications
-
Experience building or maintaining a design system or shared component library, including theming, tokens, and documentation
-
Fluency with front-end build tooling (Vite or equivalent), package management, and monorepo or workspace organization
-
Working knowledge of web accessibility standards and how to build to them from the start
Backend & .NET
-
Working proficiency in C# and modern .NET (.NET 8 or later), including ASP.NET Core, dependency injection, and building HTTP APIs
-
Comfort with relational data modeling and querying against SQL Server or Azure SQL, including the ability to recognize and fix an obvious performance problem
-
Solid understanding of REST semantics, resource modeling, OpenAPI, pagination, filtering, error contracts, and versioning
-
Working knowledge of authentication and authorization patterns including OAuth 2.0, OpenID Connect, and JWT
Quality & Ways of Working
-
Proficiency with front-end testing tooling including Vitest or Jest, React Testing Library, and Playwright or Cypress
-
Ability to translate design intent and product requirements into working software, and to push back constructively when a design will not hold up under real data
-
Comfort with ambiguity and with making a reasonable call in a greenfield codebase where the precedent does not exist yet
-
Clear written communication and a collaborative approach to code review, pairing, and design walkthroughs
Education
-
Bachelor's degree in Computer Science, Software Engineering, or a related technical discipline; equivalent professional experience will be considered
-
Relevant certifications are valued but not required
Experience
-
Minimum 5 years of professional software engineering experience, with increasing ownership over time
-
At least 3 years building production front ends in React and TypeScript, and at least 2 years building production services in .NET Core or modern .NET
-
Demonstrated experience building complex, data-dense enterprise or B2B applications rather than primarily content or marketing surfaces
-
Experience contributing to a design system or shared component library used by multiple engineers
-
Experience delivering multi-tenant SaaS in a commercial software environment where data accuracy and auditability matter
-
Experience working in high-growth software environments where velocity and pragmatism are valued alongside engineering rigor
