Work You'll Do

We are looking for a highly skilled and client-facing Forward Deployed Engineer (FDE) to sit at the intersection of engineering excellence and customer partnership. In this role, you will embed directly with our most strategic clients - particularly in the financial services sector - to understand their toughest technical challenges and help them design and implement world-class solutions using our platform. This is a high-impact, high-visibility role with direct influence on product direction.

You are equally comfortable whiteboarding microservices architecture with a client's principal engineer, running a hands-on technical workshop for a team of developers, and standing up a compelling proof-of-concept in days. You thrive in fast-moving, high-stakes environments and know how to earn the trust of deeply technical stakeholders. 

Key Responsibilities 

Client Engagement & Technical Advisory 

• Serve as the primary technical point of contact for strategic client accounts, building deep relationships with architects, engineers, and technical leaders 
• Lead discovery sessions to understand client architectures, pain points, and business objectives 
• Translate complex technical concepts into clear, compelling narratives for both technical and non-technical audiences 

Solution Design & Architecture 

• Collaborate with client architects and internal engineering teams to design scalable, production-ready solutions 
• Provide authoritative guidance on microservices architecture, event-driven systems, and cloud-native deployment patterns 
• Review and advise on client system designs, identifying risks and recommending best practices 

Proof of Concepts & Demos 

• Rapidly prototype and build POCs that demonstrate platform value in the context of a client's real-world use cases 
• Own and deliver polished, technically rigorous demos tailored to the client's specific technology stack and business domain 
• Maintain a library of reusable demo assets and reference implementations 

Workshops & Enablement 

• Design and facilitate deep-dive technical workshops, hackathons, and onboarding bootcamps for client engineering teams 
• Produce high-quality technical documentation, runbooks, and integration guides 
• Accelerate client time-to-value by enabling their teams to build confidently and independently 

Feedback & Internal Collaboration 

• Act as the voice of the customer - surface product gaps, integration friction, and feature requests to internal product and engineering teams 
• Partner with Sales, Solutions Architecture, and Product to shape the technical go-to-market strategy 

The successful candidate will possess

Core Technical Skills 

• Deep expertise in Java and Spring Boot, including building production-grade microservices 
• Strong understanding of event-driven architecture - Kafka, event sourcing, CQRS, async messaging patterns 
• Hands-on experience with microservices design principles: service decomposition, API design, resiliency patterns, observability 
• Proficiency across multi-cloud environments, with AWS as a primary platform; working knowledge of Azure and GCP 
• Familiarity with containerization and orchestration (Docker, Kubernetes) 

Emerging Technology 

• Exposure to Agentic AI frameworks and tooling - including LangGraph, LangChain, or similar orchestration frameworks 
• Practical understanding of LLM integration patterns, prompt engineering, and AI-powered application design 
• Interest in staying current with the rapidly evolving AI/ML landscape and translating it into client-relevant use cases 

Soft Skills & Presence 

• Exceptional communicator - able to lead technical conversations with senior engineers and C-suite stakeholders alike 
• Strong facilitation skills for running workshops, design reviews, and working sessions 
• Self-directed, highly organized, and comfortable managing multiple client engagements simultaneously 
• Natural curiosity and a bias for building - you'd rather spin up a demo than write a slide about one 

 Additional Key Experience

• Experience with CI/CD pipelines and DevSecOps practices 
• Contributions to open-source projects or public technical content (talks, blogs, repos) 
• Prior experience in a startup or high-growth SaaS environment 
• Relevant cloud certifications (AWS Solutions Architect, GCP Professional, etc.) 

Qualifications 

Required:

• 8+ years of software engineering experience, with significant time spent in client-facing, solutions engineering, or field engineering roles; background in financial services (banking, capital markets, payments, insurance, or fintech) strongly preferred 
• Bachelor's Degree in Engineering, Business, or equivalent field; Advanced Degree is a plus - equivalent work experience may act as a substitute for degree requirements 
• Ability to travel 20-30%, on average, based on the work you do and the clients and industries/sectors you serve
• Must be legally authorized to work in the United States without the need for employer sponsorship, now or at any time in the future
