Senior Engineering Manager | Full-Stack | Python | AWS | B2B SaaS | Must have Startup Experience

About

A well-funded, high-growth B2B SaaS company is scaling its core engineering organisation - and they need a Senior Engineering Manager to own one of the most important product lines in the business.

This is a high-ownership, high-autonomy role where you'll lead a growing team of engineers, drive the full customer journey end-to-end, and partner directly with product, GTM, and leadership to shape what gets built and how fast it ships.

The product is live, the customers are enterprise-grade, and the team is already moving fast. They need someone who can step in, take the wheel, and build.

Role Overview

You'll lead a multi-team engineering org of 10+ engineers across two or more pods, owning everything from onboarding through to feature adoption and customisation on a mature, widely-used platform. You'll set technical direction, manage managers and senior ICs, and be the single point of accountability for your org's output.

Fully in-person in New York. Fast-paced, high-accountability, no nonsense.

What You'll Own

• Full leadership of a multi-team engineering org — managing managers and senior ICs
• End-to-end customer journey: onboarding, adoption, and feature customisation
• Cross-functional collaboration with product, design, GTM, and senior leadership
• Technical direction — architecture, design reviews, and engineering standards
• Driving AI-enabled development and automation across your team
• Building a high-ownership, execution-focused culture in a fully in-person environment

Important Notes

• Strictly in-person in NYC — relocation support is available
• Startup or scale-up background is non-negotiable — large company-only profiles won't be considered
• This is a product-oriented EM role — strong technical grounding is essential
• High-autonomy, high-velocity environment — you need to be comfortable owning outcomes, not just managing process

Must-Haves

• 8+ years of software engineering experience
• 2–3+ years managing engineering teams including managers or team leads
• Full-stack product engineering leadership inside a B2B startup or scale-up (Seed–Series D)
• Deep Python and AWS expertise
• Strong product sense and proven roadmap ownership
• High-ownership mentality — bias for action, speed, and delivery
• Degree in computer science or a related technical discipline

Bonus Experience

• Hands-on experience building internal tooling or workflows using AI
• Background in API-driven products or developer infrastructure
• Experience scaling a team through rapid headcount growth

What They're Looking For

A technically sharp, product-minded engineering leader with genuine startup DNA. Someone who brings energy, takes ownership seriously, and knows how to keep a team executing at pace — without losing sight of quality or direction.
