About the Role
We are looking for a Technical Lead to drive technical execution across backend, frontend, mobile, AI, and data.
This is not a traditional people-management role. You will act as a technical partner to the founders, product team, and engineering team — turning ambiguous product goals into clear technical plans, unblocking hard engineering problems, and helping us scale the technical team.
Our current technical surface includes Python, Go, Next.js, React, React Native, Flutter, native iOS/Android, AI systems, data infrastructure, and recommendation systems. We do not expect deep expertise in every area. In the AI era, we believe strong engineering leaders should be able to use AI tools to quickly ramp up on new languages, frameworks, and codebases.
Responsibilities
Lead technical execution across backend, frontend, mobile, AI, and data initiatives
Translate ambiguous product goals into clear technical plans, milestones, owners, and trade-offs
Dive deep into hard technical problems and help drive them to resolution
Partner with founders, product, design, and engineering on technical decisions
Coordinate cross-domain engineering work and remove execution blockers
Raise the bar for engineering quality, speed, reliability, and maintainability
Help define hiring needs, role requirements, interview criteria, and technical evaluation standards
Build internal AI workflows and foster an AI-native engineering culture
Qualifications
5+ years of professional software engineering experience
Experience leading large-scope technical work across multiple engineers, teams, or product areas
Experience as a Technical Lead, Tech Lead, Engineering Lead, Head of Engineering, CTO, Staff Engineer, or hands-on Engineering Manager
Strong engineering fundamentals and technical judgment across multiple domains
Deep familiarity with AI tools and ability to use AI to augment technical execution and decision-making
Ability to operate under ambiguity and turn unclear goals into executable plans
Strong communication skills with founders, product managers, designers, and engineers
Startup-level ownership, urgency, and willingness to dive into details
Preferred Qualifications
Experience with agentic AI systems, LLM workflows, AI agents, or AI-assisted product creation
Experience with machine learning, recommendation systems, ranking, experimentation, or data pipelines
Experience building consumer-facing products, mobile products, social platforms, creator tools, or developer tools
Experience in a VC-backed startup or high-growth technology company
Experience hiring, interviewing, or defining technical bars for engineering roles
What We Offer
Top compensation package, including competitive salary and meaningful equity
Comprehensive health insurance and benefits
If you are excited about building at the frontier of AI, consumer social, and interactive entertainment, we would love to hear from you.
At Sekai, you will work with an AI-native team, move fast, own meaningful problems, and have the flexibility to explore new ideas from an early stage.
