Tech Lead (India) — Help Build WebLager’s Next Engineering Hub

Location: India

Team: Product & Development

Reporting to: Head of Product & Development (Denmark)

Why this role exists

WebLager is scaling fast, and 2026 will be a breakout year. We’re building an Indian IT office that’s not an outsourced extension of Denmark.

This is a real “build it right from day one” leadership role.

You’ll be our right hand in India — shaping the team, culture, and delivery. If you want to build something meaningful that’s expected to grow a lot next year, keep reading.

What you’ll do

You’re not here to babysit Jira. You’re here to ship, lead, and raise the bar.

●    Build and lead our India engineering team from early stage into real scale in 2026.

●    Set standards for quality and delivery — clean code, stable systems, smart execution.

●    Coach and grow people across levels: students, juniors, mid-levels, seniors.

●    Create a local WebLager community that feels like one company, not two offices.

●    Work tightly with Denmark on product, architecture, and delivery — as a partner, not a follower.

●    Stay hands-on: design, code, review, refactor, deploy.

●    Scale enterprise systems: performance, reliability, maintainability, observability.

●    Improve how we work: CI/CD, engineering rituals, docs that matter, fewer surprises.

●    Be the technical anchor when things are complex, messy, or moving fast.

What you bring

We don’t care about buzzwords. We care about proof you can build and lead.

Must-haves:

●    5+ years as a developer, with real production systems behind you.

●    Strong backend skills — ideally Python or another scripting language, plus Java/C# or similar, and also extensive database knowledge of both relational and

non-relational databases.

●    Frontend experience with a reactive framework like Angular, React, Vue, etc.

●    Experience scaling enterprise-grade systems and making architecture tradeoffs that hold up.

●    You’ve led people before (formally or naturally) and enjoy helping others grow.

●    Excellent problem-solving skills — you don’t freeze when things are unclear; you untangle them.

●    Near-perfect English (spoken and written). This is non-negotiable — you’ll work daily across countries and levels.

●    You take ownership by default and don’t need a map for every step.

Nice-to-haves:

●    You’ve helped build or grow a team from scratch.

●    Cloud + DevOps experience.

●    Product-minded engineering: you care about outcomes, not just tasks.

The kind of person who’ll thrive here

Let’s be direct:

●    You’re driven to create real results, not just “do your part.”

●    You want to build something from the ground up and shape the future of a company.

●    You lead with calm, clarity, and high standards.

●    You’re motivated beyond the norm — you don’t settle for “good enough.”

●    You know a Tech Lead is someone who steps up, helps others win, and keeps shipping.

●    You’re hungry to learn, and confident enough to challenge weak solutions.

The kind of person who won’t

Also direct:

●    If you expect everything to be built around you, look for another job.

●    If you want Denmark to hand you tasks, this isn’t it.

●    If you avoid responsibility or hard conversations, this will hurt.

●    If “average and comfortable” is your goal, don’t apply.

We’re building an exceptional team. Mediocre doesn’t survive here.

What you get

●    A rare chance to build an office, a culture, and a high-performing team in India from scratch.

●    Direct partnership with Danish leadership and product org.

●    Real influence over architecture, standards, and execution.

●    A company that values ownership and speed over politics.

●    Massive growth opportunity as the India office scales in 2026.

●    Competitive salary + benefits.

How to apply

Only reach out if you genuinely believe you’re the right fit and you’re motivated to build something one-of-a-kind.

Send: (This is mandatory)

●    A short page about you and what you’ve built.

●    CV/LinkedIn/GitHub/portfolio.

●    2–3 projects you’re proud of, and why.
