Sift is building the infrastructure that modern engineering teams rely on to design, test, and operate complex machines.

Our platform provides real-time observability for high-frequency telemetry, enabling engineers to debug complex systems faster, identify failures earlier, and operate safely in environments where reliability is mission-critical.

Sift was founded by engineers who worked on some of the most ambitious aerospace programs in history — including Dragon, Falcon, Starlink, and Starship at SpaceX. Those programs exposed the limits of existing tools for telemetry analysis, system debugging, and mission-critical validation. Sift was built to solve those challenges and is now supporting teams building advanced systems across aerospace, defense, robotics, energy, and industrial manufacturing.

We are expanding our go-to-market presence across Europe and are hiring a Sales Manager based in London to help build and grow Sift’s customer base in the region.

This role is ideal for an experienced sales professional proficient in highly technical sales, familiarity with the European hardware / defense landscape, and interest in kickstarting a new sales region for a high growth startup.

The Role

As an Sales Manager at Sift, you will own complex sales cycles with engineering and technical teams building some of the most advanced systems in the world.

You will work closely with the existing sales and technical teams to identify new opportunities, guide customers through technical evaluations, and close deals that deliver measurable engineering value.

This role involves working with technical stakeholders such as engineering leaders, systems engineers, and program managers, while also aligning executive buyers around commercial outcomes.

The role is based in London, with travel across Europe for customer meetings, industry events, and technical evaluations when required.
