Full Stack Tech Lead — Founding Engineer

About the Role

You will be hands-on in production - owning a speech AI API platform, building and scaling backend and frontend systems, debugging failures in real time, and leading a team of 4–8 engineers and interns.

This is a founding-stage hire. You will be among the first engineers shaping how we build - your technical decisions will define the architecture, standards and culture of the engineering team for years to come.

You will report directly to the CEO and own architecture, code quality, delivery, infrastructure decisions and mentoring across the full stack.

If you are someone who thrives in high-ownership environments, stays calm when things break, and cares deeply about building systems that actually work - this role is for you.

What You Will Own

Own architecture, code quality and delivery across a full stack codebase

Design and build scalable backend APIs and microservices supporting real-time speech processing and billing

Own backend architecture decisions - database design, service structure and data flow

Manage cloud infrastructure on AWS

Ensure APIs and services are always online and recover cleanly from failures

Debug production issues in real time across audio pipelines, APIs and data workflows

Set engineering standards, conduct code reviews and mentor junior team members

Coordinate engineers and interns across the team

Own CI/CD pipelines and deployment workflows

What You Actually Are

You are comfortable making decisions with incomplete specs

You document assumptions and tradeoffs without being asked

You prioritise predictability over cleverness

You stay calm when production breaks and fix things without waiting for permission

You lead by example - your team follows your technical standard, not just your title

You do not wait to be told what to do when something is wrong

Non-Negotiables

5+ years in backend, systems or full stack engineering

Expert in TypeScript - comfortable owning server and client code end-to-end

Strong production API design - REST, WebSockets, auth, rate limiting

AWS production experience

Testing discipline - unit, integration and e2e

Security mindset - secrets management, API keys, PII boundaries

Familiarity with data privacy and compliance requirements across different regions

Comfortable being accountable for system behaviour, not just code

Strong Plus

Real-time systems - WebSocket session management, audio streaming

Multi-tenant SaaS - billing, usage tracking, plan management

Observability and monitoring in production

AI and API integration across multiple third-party providers

Speech and ASR domain knowledge

Experience with regional data compliance and privacy regulations - PDPA, PDPL or similar

This Role Is Wrong For You If...

You prefer research over production

You dislike being on-call or handling outages

You avoid debugging under pressure

You need highly detailed specs before moving forward

You are optimising for title, visibility or resume optics

Who Will Thrive Here

Engineers who take full ownership of what they build and ship

Systems thinkers who see the whole pipeline, not just their part

Calm debuggers of complex and unexpected production failures

Technical leaders who lead by doing, not just directing

High-agency individuals who care about real-world impact

What You'll Get

Up to USD 2,000 per month + meaningful ESOP

Fully remote - open to candidates in Vietnam, Pakistan, Thailand, Indonesia and Central Asia with good connectivity and proper remote setup

Report directly to the CEO with full technical ownership

Lead and grow a team of 4–8 engineers

Growth measured by system ownership and trust, not titles
