About Blowtrumpet

At Blowtrumpet
, we're building a
next-generation Ad-Tech SaaS platform
that automates performance marketing through our proprietary
DSP + SSP ecosystem
— connecting advertisers and creators through
ethical, gamified, and intelligent ad experiences
.

We're an
AI-native, product-first company
in investment mode — bootstrapped, deliberate, and building fast from our
South Delhi garage environment
.

Our goal is to create
futuristic, scalable, and cloud-agnostic software
that can be hosted across
private VPS or bare-metal infrastructure
— without compromise.

If you want to work in a
high-responsibility, no-mediocrity
product environment and help take a pre-revenue startup from garage to global, this role is for you.

Role Overview

We're looking for a Full-Stack Developer
who can work across the
MERN stack
using
NextJS, NestJS
, and modern, future-ready frameworks.

You'll be responsible for developing and deploying
core modules across 18 microservices
, building a
front-end experience tied to Figma precision
, and ensuring
backend efficiency, scalability, and security
.

You'll work closely with
design, product, and development teams
to implement directions for an ad-tech software suite that's complex, performance-oriented, and designed for a
multi-tenant, AI-native, programmatic future.

This is a full-time onsite opportunity in South Delhi
—
no remote or hybrid options available.

What You'll Do

• Develop and maintain
  end-to-end features
  across a
  MERN stack
  with
  NextJS and NestJS
  integration.
• Contribute to and maintain a
  microservice-driven architecture
  (18+ ready services).
• Implement
  front-end components
  with
  pixel-perfect precision
  from
  Figma and Adobe XD designs.
• Collaborate with product and design teams
  to bring gamified SaaS features and ad-tech flows to life.
• Optimize performance for
  cloud-agnostic deployment
  on
  private VPS and bare-metal infrastructure.
• Write clean, maintainable, well-documented code — ready for scale.
• Build reusable component libraries
  and
  internal APIs
  for modular growth.
• Maintain best practices for
  security, CI/CD, versioning, and testing.
• Participate in on-site technical reviews and whiteboard sessions.

Technical Requirements

• Strong experience with
  MongoDB, , , (MERN)
  .
• Proven proficiency in
  NextJS
  and
  NestJS
  (preferred).
• Solid understanding of
  JavaScript (ES6+), TypeScript
  ,
  TailwindCSS
  ,
  HTML5
  , and
  CSS3
  .
• Ability to implement
  frontend design systems
  from
  Figma
  and
  Adobe tools
  with pixel accuracy.
• Understanding of
  API integration, microservices communication
  , and
  authentication systems (OAuth2/JWT)
  .
• Hands-on with
  server configuration
  ,
  deployment scripts
  , and
  cloud-agnostic environments
  (VPS, DigitalOcean, AWS Lightsail, bare-metal setups).
• Working knowledge of
  data structures, algorithmic problem-solving
  , and
  asynchronous programming
  .
• Ability to debug and optimize performance across full-stack pipelines.

Mindset & Expectations

• On-site role only:
  candidate must be Delhi-based (preferably
  South Delhi
  ) and able to
  work from the office daily.
• Must be available for on-site interviews and coding assessments
  (online interviews are
  not conducted
  ).
• Must demonstrate
  independent thinking, ownership, and adaptability
  in a small-team environment.
• Comfortable with
  uncertainty and velocity
  — this is a
  garage-based, investment-mode startup
  , not a service shop.
• Strong bias for
  execution, speed, and accountability
  .
• AI-native mindset
  but strong
  manual coding skills
  — must be able to build without relying on AI tools.
• Must provide
  references or work samples
  demonstrating prior product work, preferably
  SaaS, startup, or ad-tech related.
• No mediocrity tolerated
  — only candidates confident in their craft and willing to grow rapidly should apply.

Why This Role Matters

• You'll be working on
  the core product architecture
  that powers the future of
  ad automation and creator monetization
  .
• You'll collaborate across
  design, product, and engineering
  to define how
  gamified SaaS experiences
  are built.
• This role is
  career-defining
  — for those who want to grow into
  Lead Engineer / CTO tracks
  in a fast-moving product company.
• High ownership, deep learning, and direct founder access
  from day one.

Ideal Candidate

• 3–6 years of
  hands-on experience
  with full-stack development.
• Product background preferred —
  service company experience won't fully align
  .
• Comfortable in a
  garage-like, pre-revenue environment
  where learning and shipping matter more than structure.
• Has built or contributed to
  real-world SaaS or platform products
  .
• Ambitious, self-motivated, and comfortable being part of a
  small, intelligent team building something audacious.

Interview & Application

• On-site interviews only.
• Technical test and programming assignment
  required.
• Include
  links to prior work, GitHub/portfolio
  , and
  references
  from mentors or previous managers.

Final Word

This isn't a routine development job — it's a mission-critical opportunity
to help
design, code, and scale
a next-gen ad-tech product from the ground up.

You'll be writing code that defines how advertisers, creators, and marketers interact with a
gamified, ethical, and intelligent ecosystem.
