We're not a startup, but we move like one when it matters. Right now, we're in the middle of a serious modernization of our payment integrity platform: replacing legacy .NET, rebuilding the experience layer around modern web frameworks, fixing data bottlenecks, and getting the product ready to scale.We're hiring a Full Stack Engineer whose center of gravity is the front end. You'll spend most of your time designing and building the web experiences our customers actually live in - modular Angular applications, micro-frontend architecture, design systems, accessibility, performance, and the kind of interaction quality that makes a complex product feel simple. You'll also reach into the backend with confidence: shaping the .NET APIs your UI depends on, tuning the queries that feed your screens, and making sure the seams between client and server are clean. You'll work closely with product, UX, and DevOps to ship customer-delighting features at scale.Here's what makes this role different: you're not just a frontend engineer who "also knows AI." We want someone who has already figured out that tools like Cursor, Claude Code, and Codex aren't toys - they're force multipliers. You'll use AI agents every day to tear through component refactors, framework upgrades, test coverage, and the backend work that comes with full-stack ownership. But you also know when the AI is wrong, when to step in, and how to keep quality high. Think of it as having a junior engineer with infinite energy and zero judgment - your job is to supply the judgment.ESSENTIAL JOB RESPONSIBILITIES & KEY PERFORMANCE OUTCOMESLead the front-end modernization of the productThis is the bulk of what you'll do. You'll:Design and buildReactapplications that are modular, testable, and accessible by default-with a real point of view oncomponentarchitecture, state management, routing, and shared libraries.Own the experience layer end to end: design system contributions, responsive layouts, accessibility (WCAG), client-side performance, error and loading states, and thesmall detailsthat separate a workflow people tolerate from one they trust.Partner with UX on flows that hold up under real customer workloads-dense tables, long-running operations, complexpermissioning-not just happy-path mockups.What success looks like:Customers notice the difference. Workflows feel faster, clearer, and more reliable, and the screens that used to generate support tickets stop generating them.The front-end codebase becomes something the team is proudof:consistent patterns, real test coverage, stable build and release tooling, and a design system that other engineersactually reachfor instead of reinventing.Deliver full-stack features against a real .NET + PostgreSQL stackYour features don't stop at the API boundary. You'll:Shape and extend the .NET APIs your front end consumes-RESTful, versioned, and built for correctness and maintainability, not just "it works."Make pragmatic backend changes: adding endpoints, refactoring service boundaries, tightening contracts, and replacing legacy .NET code whereit'sblocking the experienceyou'retrying to ship.Get your hands into SQLwhen the UI demands it-query performance, indexing, transactional correctness-and contribute to data pipelines (Kafka, event-driven flows) when the work calls for it.What success looks like:You ship features end to end without needing a backend engineer tohand-holdeach one. Critical paths land in modern code, sprint over sprint.APIs that back your UIs get faster and more reliable. Database hot spots stop waking people up at night.Ship modernization work at a pace that surprises peopleThis is your superpower. You'll:Use AI agents (Cursor, Claude Code, Codex) to power throughcomponentmigrations, framework upgrades, API extraction, test scaffolding, and documentation-while catching hallucinations and preventing regressions before they hit a PR.Build reusable playbooks the team can actuallyfollow:prompt templates, repo-level agent instructions, migration checklists, review heuristics, and clear "definition of done" standards for AI-assisted changes-on both the front-end and backend sides of the codebase.What success looks like:You measurably move the needle-more modules migrated per sprint, faster PR turnarounds-without a spike in production bugs.The team gets better because of you: PRs are clearer, test coverage grows, documentation stays current, and the same mistakes stop repeating.Own it like it's yours - especially because this is healthcareYou'll:Build with security and privacy as defaults, not afterthoughts-both on the client (safe data handling, careful state, sensible telemetry) and on the server (least privilege, auditability). This is healthcare. Getting it wrongisn'tan option.Put real quality guardrails in place:componentand integration tests, end-to-end coverage on the flows that matter, CI that blocks bad changes, structured logging, and front-end observability that tells you what usersactually experiencebefore they tell you.Review code thoughtfully, have honest architectural conversations, and raise the bar without being a jerk about it.What success looks like:Fewer severity-1 incidents. When something does go wrong, root cause takesminutes, nothours.Automated test coverage grows meaningfully on modernized code-across the UI, the API layer, and the integration seam between them. The team stops relying on "just test it manually."Work with real humans to ship things that matterYou'll:Partner with analysts, stakeholders, designers, and other engineers to turn business problems into working software-not just technically correct software, but software thatactually solvesthe problem.Help build delivery plans that are honest about trade-offs. "Right" vs. "right now" is a real tension-you'llhelp the team navigate it with pragmatic milestones.What success looks like:Delivery is predictable. Customer onboarding milestones are met. Features ship with confidence, not crossed fingers.REQUIRED SKILLS & EXPERIENCE5+ years building and shipping production systems. Not side projects-real software with real users.You'reable to work independently and collaboratively in fast-moving teams.Deep front-end experience withReact/Next.js(or comparable depth inAngularwith awillingness to lead inReact).You'vebuilt andmaintainednon-trivial applications:componentarchitecture, state management, routing, forms, accessibility, and performance.You'veworked at the scale whereshared librariesand design systems become real problems-not slides.Strong fundamentals across the modern web platform: TypeScript, HTML, CSS, browser performance, accessibility, testing (unit,component, end-to-end), and the build/release tooling that goes with it.Solid working experience with C# and modern .NET (Core and beyond). Youdon'tneed to be the deepest backend engineer in the room, but you can confidently read, extend, and refactor service code-andyou'vedone meaningful work in real codebases, not just greenfield.Comfortable with SQL-enough to design reasonable schemas, write and tune the queries your UI depends on, and recognize when a performance problem belongsatthe database, not the client.API design experience-you'vebuilt and consumed service-oriented APIs with real versioning, auth, reliability, and testing practices, and you have opinions about what makes a backend pleasant (or painful) to integrate with from a front end.Cloud experience withAWSand/orAzure.AWSis particularly relevant here.Youactually useAI coding tools as a daily driver. Cursor, Claude Code, Codex, or similar-and not just for autocomplete.You'veused agents for multi-file refactors, migrations, test generation, and review workflows. You have opinions about what works and whatdoesn't.PREFERRED QUALIFICATIONSYou'veled or played a significant role in a real front-end modernization-AngularJS toReact, jQuery to a modern framework, a monolithic UI to micro-frontends, or similar. You know where the bodies areburiedand you have the scars to prove it.Deep design system orcomponentlibrary experience-you'vebuilt one, contributedsubstantially toone, or hauled a team off a tangle of one-off components onto something coherent.You'vedone a legacy ASP.NET / .NET Framework modernization on the backend side.Experience with distributed systems tooling-Kafka, event-driven architectures, or working with Postgres alongside SQL Server.You'vehelpedestablishagent-friendly engineering practices: writing repo instructions that AI tools can follow, breaking work into agent-sized tasks, setting up CI guardrails for AI-generated code, feature flags, canary deployments-any part of the progressive delivery toolkit.You communicate clearly. Good PR descriptions, straightforward design docs, pragmatic collaboration, low ego. Wedon'tneed a rockstar-we need someone the team trusts.Background in regulated domains (healthcare, fintech, payments) where "move fast and break things" will get you fired.***The US base salary range for this full-time position is:The specific salary offered to a candidate may be influenced by a variety of factors including but not limited to the candidate's relevant experience, education, and work location.
