Lead Engineer - AI-Native Email App

Strong software engineering background with significant experience building and shipping production systems.

Deep technical expertise in one or more areas such as backend, frontend, distributed systems, APIs, databases or cloud infrastructure.

Strong system design and architecture skills with experience making technical decisions for complex or high-scale systems.

Strong coding ability and willingness to remain hands-on.

Proven experience leading major engineering projects or providing technical leadership to other engineers.

Comfortable reviewing code, debugging complex issues and working directly with production systems.

Able to explain complex technical decisions clearly and influence engineers across teams.

Strong product sense and ability to connect technical decisions to customer and business outcomes.

Able to work fast with ambiguity and take ownership from problem definition through production.

Strong judgment around when to move quickly, when to simplify and when deeper engineering investment is required.

Engineers who want a leadership title but no longer want to write or review code.

People who only want to work within one narrow technical area.

Engineers who wait for complete specifications before starting.

Candidates who over-engineer solutions when a simpler approach would achieve the outcome.

Engineers who focus only on implementation without understanding the product or business problem.

People who avoid production incidents, difficult debugging or ownership after release.

Candidates who make vague claims about technical leadership without being able to explain what they personally designed, built, shipped or scaled.

We are looking for technical leaders with real engineering career highlights.

A strong highlight is not simply having a senior title or working at a famous technology company. A strong highlight means you personally designed, built, shipped or scaled a serious product, platform or system and can go deep into the technical decisions behind it.

You should be able to demonstrate both technical depth and technical leadership — someone who can solve difficult engineering problems personally while making the engineers around them stronger.

English is our main working language across global teams. Strong English communication is required.

Our process is designed to move fast:

Online assessment or practical task

Technical interview

CEO / final round

For strong candidates, we aim to complete the process and make an offer within 1 week from the start of the interview process. Candidates who complete assessments quickly will be prioritized.
