Job description

Senior Software Engineer (Product)

Location: Boston, MA

Employment Type: Full time

Location Type: Hybrid

Department: R&D

We are seeking a product-minded Software Engineer to join our core team. In this role, you’ll take ownership across the entire product stack designing and building backend systems, spanning into frontend when the product demands it, and bringing genuine product instinct to every decision you make.

This is not a backend role or a full-stack role in the conventional sense. We’re looking for engineers who are energized by customer pain points, not just technical problems, who understand the security landscape well enough to see its limitations, and who are excited to reimagine it from the ground up. As an AI-native company, we lean in heavily to AI-assisted development, and we expect you to as well.

As a key member of the team, you’ll help shape what we build and why while collaborating directly with customers, contributing product opinions alongside technical ones, and operating with the kind of broad ownership that only a small, fast-moving team can offer.

Responsibilities

• Design, implement, and maintain core backend systems including APIs, data pipelines, and workflow engines powering 7AI’s agentic security platform.
• Span the full product stack using AI-assisted development, from backend services to frontend interfaces.
• Translate customer pain points into product requirements, and product requirements into shipped software.
• Engage directly with customers to deepen understanding of the problem space and validate solutions.
• Contribute product and design judgment not just implementation, shaping what gets built and how it works.
• Choose and implement appropriate technologies and architectures with a can-do, fast-shipping attitude.

Requirements

• 5+ years of backend or full-stack engineering experience, with strong fundamentals in system design, APIs, and data modeling.
• Hands-on experience with cloud design and implementation (AWS preferred); familiarity with a wide range of cloud technologies and architectures.
• Proficiency in TypeScript/Node.js or similar modern server-side languages; Python a plus.
• Fluent with AI coding tools such as Claude, Cursor or similar.
• Demonstrated product instinct: you think about why something is being built, not just how, and you’re comfortable engaging directly with customers.
• Experience in or strong curiosity about the security domain — SIEM, SOAR, EDR, MDR, or incident response workflows.
• Excellent software development skills with strong problem-solving and communication abilities.
• Bachelor’s degree or equivalent in a relevant field.

Nice to Have

• Experience with workflow automation, SOAR platforms, or security orchestration.
• Familiarity with Temporal or similar workflow engines.
• Design sensibility — you don’t need to be a designer, but you know when something isn’t right.
• Background in a product-facing or customer-facing engineering role.
