Lead Engineer/ Architect (.NET) - Finance Group

Role Description

This is a remote position.

We are hiring a Lead Engineer/ Architect (.NET), a hands-on technical leader who will accelerate the build-out of the next generation of our online banking platform for US Banks and credit unions on ASP.NET Core and C#. You will spend a significant portion of your time writing production code and owning architecture, while also mentoring engineers and setting the technical bar.

You will partner day-to-day with Finance Group technology leaders on product and delivery, the Embrace Technology group on shared architecture, cloud and DevOps standards and Venture Labs / the Embrace AI Group to bring emerging capabilities into the platform.

At its core this is a forward-deployed engineering (FDE) practice with an AI-first, new-product mandate. You will embed with financial institutions and internal product partners, turn ambiguous problems into shipped product and lead a small team of highly empowered, highly skilled engineers who take ideas from conceptualization to launch in weeks - not quarters.

You will go full-stack from modern UX/UI through public REST APIs down to a .NET control plane and treat large language models and agentic AI services as first-class building blocks of the platform rather than bolt-ons.

Key Responsibilities

• Architect and hands-on build the new ASP.NET Core / C# online banking platform - system design, service boundaries, data modeling and API contracts.
• Design and implement critical features and platform components; lead code and design reviews, setting the technical bar.
• Lead and mentor a small agile team - run sprints, unblock engineers, own delivery commitments, coach through 1:1s and pair programming.
• Partner with Finance Group technology leaders, product, QA and security to translate business and regulatory needs into robust solutions.
• Collaborate with the Embrace Technology group on shared architecture, cloud and CI/CD standards and with Venture Labs / Embrace AI Group to embed AI capabilities (AI-assisted dev, predictive insights, fraud/risk monitoring) into the platform.
• Drive engineering best practices - testing, CI/CD and adoption of modern AI dev tools.
• Operate as a forward-deployed engineer - embed with internal product partners to co-design solutions, then rapidly conceptualize, prototype and launch new products, compressing concept-to-production from quarters to weeks.
• Lead AI-first, new-product development end-to-end - design and ship LLM- and agent-powered capabilities using services such as Google Vertex AI / Gemini, OpenAI (and Azure OpenAI) and orchestration frameworks like LangChain, with disciplined evaluation, guardrails and cost / latency management.
• Build full-stack and real-time - modern, accessible UX/UI, public REST APIs and live experiences via SignalR on .NET Core / C# control plane, with event-driven services through Azure Service Bus / messaging, etc.
• Own the cloud and delivery foundation - infrastructure-as-code with Terraform, CI/CD on GitHub (Actions) and containerized, repeatable deployments across Azure and/or AWS.
• Engineer security and compliance in by design - identity and access management (OAuth2 / OIDC, SSO, MFA), secrets management and data protection aligned to PCI DSS, SOC 2 and FFIEC, with auditability from day one.
• Build and empower the team - recruit, coach and unblock a small squad of progressive FDEs, giving them the autonomy, tooling and technical bar to ship safely and fast.

Requirements

• 5+ years building modern, data-intensive .NET web applications, with a proven tech-lead / lead-developer track record and direct team ownership.
• Polyglot. Expert-level C# and .NET (Framework and modern .NET / Core); strong SQL and Microsoft SQL Server; solid REST API experience at scale.
• Proven experience in financial services / online banking, with strong preference for platforms serving US Banks, credit unions, or other regulated FIs.
• Front-end experience with modern Javascript/UI frameworks like Angular / React. Familiarity with classic frameworks like ASP.NET, Razor templates, Htmx, Bootstrap, Orchard Core, etc is a strong plus for modernizing.
• Experience with cloud (Azure, AWS), DevOps and CI/CD; understanding of US banking security and compliance (PCI DSS, SOC 2, FFIEC guidance).
• Strong communicator across engineering and business stakeholders (Finance Group, Embrace Technology, Venture Labs); excellent ownership and problem-solving.
• Comfortable in a highly remote, fast-paced, agile environment. Bachelor's in CS, Software Engineering, or related field (or equivalent experience).
• Demonstrated 0→1 product delivery at speed - ideally in a forward-deployed, customer-embedded, or startup / venture environment.
• Hands-on AI/LLM application development - prompt and context engineering, RAG and agentic patterns on at least one major platform (Vertex AI / Gemini, OpenAI, or Azure OpenAI) with orchestration such as LangChain and a pragmatic grasp of evaluation, guardrails and cost.
• Real-time and event-driven experience - SignalR, Azure Service Bus or equivalent messaging - and public REST API design at scale.
• Strong platform / DevOps depth - Terraform (IaC), GitHub Actions CI/CD, containerization and multi-cloud (Azure and/or AWS).
• Identity, security and compliance depth for regulated FIs - IAM / OAuth2 / OIDC, SSO / MFA, secrets management and PCI DSS / SOC 2 / FFIEC.

Benefits

• Competitive salary commensurate with experience; 100% remote with autonomy.
• Career advancement across the Embrace portfolio; the chance to shape a platform used by hundreds of US banks and credit unions with the Embrace AI Group and Venture Labs.
• A high-autonomy, AI-first engineering culture where small teams of empowered FDEs take ideas from concept to launch - and see them used by hundreds of US banks and credit unions.
