Job Description:

This is a Senior Software Engineer role with a strong customer focus. As a Forward Deployed Engineer (FDE), you will be embedded at the intersection of product, engineering, and customer success. Relative to other Software Engineers, FDEs at Tessl trade long-running project depth for customer proximity and exploration. You might spend a week working closely with a design partner, then embed inside a Tessl team for several weeks as an ad-hoc tech lead to deliver a feature that helps close a deal, then return to customers or repeat the cycle elsewhere. The key outcome is 'shipped features that win customers'. Success in this role requires strong working relations with customers and engineering teams alike, seen as a trusted technical partner for both.

Job Responsibility:

Work directly with design partners and early adopters (typically 100+ employee companies) as a trusted technical advisor
Embed inside Tessl teams as an ad-hoc technical lead to drive customer-motivated features to completion
Identify concrete product gaps blocking adoption or deals, and turn them into shippable solutions
Build production code and rapid prototypes
Apply strong judgment to balance speed and quality when the outcome isn’t known upfront
Act as a tight feedback loop between customers and product/engineering, working in close partnership with Sales and Support while maintaining an engineering focus

Requirements:

Strong software engineering experience (typically 5+ years) — ideally with a track record of delivering complex, production-grade systems across backend, API, and tooling domains
Familiar with multiple programming languages and frameworks, as well as system design and distributed systems
Participate in an on-call rota like all other senior engineers
Demonstrated ability to leverage AI assistants and coding agents to accelerate development workflows (e.g., Claude Code, Cursor, Codex or equivalent)
Power user of coding agents, able to explain their inner workings and get the most out of them
Experience building or integrating systems that leverage AI/ML components, pipelines, or agent workflows
Ability to translate ambiguous product requirements into actionable engineering tasks
Demonstrated ability to self-organize and drive projects with minimal operational overhead
Able to operate independently, in short-term task forces inside Tessl, or embedded directly with customers

What we offer:

Competitive salary
Equity package
Health insurance with Aviva that extends to partners and dependents
Pet-friendly office
Team socials, lunches, drinks and off-sites
