U.S. GenAI startup, Burlington/Cambridge Office

Build the bridge between cutting-edge AI and real-world software development

Location: Quincy, MA (Hybrid: 3 days/week on-site with customer in Quincy, 2 days/week at 1 Kendall Square, Cambridge)

Travel: Minimal - role is based in Greater Boston area

Compensation: $160,000 - $185,000 annually

We're looking for a Forward Deployed Software Engineer who thrives at the intersection of cutting-edge AI technology and real-world enterprise software challenges. You'll embed directly with our customer's engineering team in Burlington, MA, helping them revolutionize their software development with Blitzy.

This isn't a typical solutions engineer role. You'll write production code, architect solutions, and work shoulder-to-shoulder with customer engineering teams to deliver transformative outcomes. You're equally comfortable debugging a complex integration, participating in sprint planning, or whiteboarding architecture with a CTO.

This role requires being on-site with the customer in Quincy 3 days per week and at Blitzy headquarters (1 Kendall Square, Cambridge) 2 days per week. This structure ensures deep customer partnership while maintaining connection to our core engineering team.

• You deploy Blitzy into complex enterprise environments, navigating technical constraints while delivering immediate value
• You write custom integrations and extensions that unlock new use cases for customers
• You translate ambitious business goals into concrete technical implementations using Blitzy's AI capabilities
• You identify patterns across customer needs that influence our product roadmap
• You become a trusted technical advisor to engineering leaders, earning their confidence through hands-on expertise
• You drive successful POCs that expand into enterprise-wide deployments
• You contribute code and insights back to our core platform based on field experience

• Embed with customer teams during critical implementations, serving as their technical co-pilot
• Participate in customer sprint planning, architecture reviews, and technical decision-making
• Build custom solutions that demonstrate Blitzy's capabilities in their specific environment

• Write production-quality code to integrate Blitzy with existing enterprise systems
• Develop reusable patterns, scripts, and tools that accelerate customer adoption
• Debug complex issues spanning customer infrastructure and our platform
• Create technical demos that showcase advanced use cases

• Decompose executive vision into actionable engineering roadmaps
• Identify expansion opportunities within accounts based on technical insights
• Collaborate with our product team to prioritize features based on field experience
• Contribute to our technical documentation and best practices

• 4-10 years of software engineering experience with a track record of shipping production code
• Fluency in multiple programming languages (Python, JavaScript/TypeScript, Java, Go, or C#)
• Deep understanding of modern software development practices (CI/CD, microservices, cloud architecture)
• Experience with enterprise development workflows, including Agile/Scrum methodologies
• Hands-on experience with Jira and enterprise software development lifecycle
• Proven ability to navigate complex technical environments and stakeholder relationships
• Strong communication skills—you can explain technical concepts to anyone from intern to CTO
• Must be based in or willing to relocate to Greater Boston area for this hybrid role

• Experience at high-growth startups or in customer-facing engineering roles
• Background in AI/ML, developer tools, or enterprise modernization projects
• Track record of technical thought leadership (blogs, talks, open source contributions)
• Experience with legacy system modernization or large-scale migrations
• Passion for the future of AI-powered software development

Unlike traditional FDSE roles that focus on configuration and support, you'll be:

• Writing production code that directly impacts customer success
• Shaping AI adoption at the frontier of what's possible with generative AI
• Influencing product direction through direct field experience
• Working with our AI platform that generates complete applications, not just code snippets
• Growing with flexibility to transition into core product/platform engineering
