What is a founding full stack engineer?

A Founding Full Stack Engineer is an early, core technical team member at a startup who is responsible for building both the front-end and back-end of the company's product. This role goes beyond typical engineering, often involving product decisions, architecture design, and collaborating directly with the founders. Founding Full Stack Engineers help shape the company's culture, technical direction, and can have significant equity stake. Their work is crucial in taking the business from idea to launch, often in a fast-paced, resource-limited environment.

What are the key skills and qualifications needed to thrive as a founding full stack engineer?

To thrive as a Founding Full Stack Engineer, you need expertise in both front-end and back-end development, deep knowledge of programming languages like JavaScript, Python, or Ruby, and experience with scalable architectures, often backed by a degree in computer science or equivalent experience. Familiarity with frameworks (React, Node.js, Django), version control systems (Git), cloud platforms (AWS, GCP), and DevOps practices is typically required. Strong problem-solving, initiative, adaptability, and excellent communication distinguish successful candidates, enabling effective collaboration in a startup environment. These skills and qualities are crucial for building robust products rapidly and influencing the company's technical direction from its early stages.

What unique challenges might a founding full stack engineer face when joining an early-stage startup?

As a Founding Full Stack Engineer at an early-stage startup, you'll often balance building core product features with setting up foundational technical infrastructure. This role typically requires wearing multiple hats, from architecting systems and writing code to making critical technology decisions and collaborating closely with non-technical founders. You may encounter challenges such as ambiguous requirements, shifting priorities, and limited resources, but you'll also have significant influence over the company's technical direction. The dynamic environment encourages rapid learning and offers accelerated career growth, particularly for those who thrive in fast-paced, collaborative settings.

Founding Full-Stack Engineer - Takt

Pear

San Francisco, CA • On-site

Full-time

Re-posted 16 days ago

Job description

About Takt
Our Vision: A world where factories think.
Takt is building the brains of factories.
Factories have spent the last decade digitizing: adding sensors, software, and
dashboards everywhere. Yet most factories aren't meaningfully smarter. Data is
fragmented across disconnected systems, locked in reports, and dependent on tribal
knowledge living in people's heads.
The hard problem isn't collecting data, it's turning it into institutional intelligence.
Takt is building the brains of factories. We're closing the loop from data → information
→ insight → action by orchestrating AI agents with deep operational context across
the entire manufacturing stack. These systems reason about what's happening, why it's
happening, and what to do next, acting as a continuous thought partner to factory
leadership across sales, operations, supply chain, and finance.
This is not a chatbot or another analytics layer. We're pushing the frontier of AI
reasoning and decision-making in real-world, high-stakes environments. Just as Tesla
redefined the car as a software-first system, Takt is redefining manufacturing as a
software-defined industry.
Funding
Takt is funded by Pear VC (backed Doordash, Gusto) and is part of the
PearX accelerator program.

Founders
Takt was founded by Adhitya Raghavan (CEO) and Will Zunker (CTO).
Adhitya is from a small village in South India and first learned about factories by working
as an operator on his father's shop floor. His journey through squash took him to
Princeton (Mechanical & Aerospace Engineering), Harvard (MBA, Baker Scholar), and
Bain. Now, he's bringing it full circle, building Takt to solve the very pain he experienced
firsthand in factories and aiming to put a dent in the $8 trillion of waste that occurs in
manufacturing globally.
Will an MIT PhD has deep experience in optimizing manufacturing processes through
physics-based modeling and AI, driven by a belief that advanced methods can
fundamentally transform how things are made. Along the way, he built open-source
tools and collaborated with engineers across diverse manufacturing sectors, learning
firsthand the challenges of waste and inefficiency on the factory floor. Now, at Takt, he's
channeling that journey into building technology that helps factories run smarter, faster,
and with less waste.
Core Cultural Values
  1. Stupid enough to make our dreams a reality: We are dreamers who build a better world. We own our decisions. We have the irrational belief and hunger to work until our dreams are a reality
  2. The last one standing: Every single person takes ownership of their work with a gritty resourcefulness and dares to fight for it with every ounce of their energy.
  3. Insatiable curiosity: Its always day 1 and we are an empty cup, a dry sponge ready to learn. Approaching every action with humility and scientific rigor and adopting a Kaizen mindset.
  4. The best F1 team in the stadium: We win together and lose together; every person plays a crucial role to win the race. We have high expectations, trust our teammates and create the environment for everyone to shine. In the path the victory, we celebrate every small professional and personal win cherishing the journey

Role
Founding Full Stack Engineer
  • Location: San Francisco, in person 4 to 5 days a week. Open to candidates willing to relocate.
  • Hours: 50 to 70 hours per week with space for personal interests
  • Compensation: 120-180K
  • Equity: To be discussed (0.5-1%)
  • Prior experience: 2-3 years minimum

You will be the first engineering hire and will work directly with the founders to build the

real long-term impact.
Core Technical Requirements
  • Experience deploying and maintain full stack production grade code at scale to support 50-100 enterprise customers with minimal downtime
  • Strong cloud infrastructure skills (Azure preferred).
  • Deep experience with data pipelines, especially cleaning messy, inconsistent real-world data AI-native in approach to coding utilizing new-age tools (e.g. Claude Code) to develop with speed.
  • Strong generalist coding skillset especially on the back-end side.
Nice to have
  • Experience shipping production AI/ML or LLM systems end-to-end (not research prototypes).
  • Comfortable owning LLM tool orchestration, chain design, agent delegation, prompt engineering, and evaluation methodology.
  • Hands-on experience integrating with enterprise systems like ERP, MES, and other data historians (Microsoft Business Central/ SAP)
  • Working knowledge of relational + SQL databases
  • Familiarity with per missioning models, data governance, or SOC2/GDPR.
  • Experience engaging with IT teams and meeting security requirements for enterprise customers.
Mindset & Work Style
  • Strong sense of agency and ownership: comfortable making fast decisions and revising them.
  • Shipping and moving quickly, makes practical choices, and delivers value to customers
  • Willing to learn and can get things done, even if they don't know it from the get-go
  • Thrives with incomplete information
  • Passion for the product: speaks their mind, contributes ideas, and pushes for the best solution
  • Long-term commitment to the mission, we are building foundational systems, not short-lived features. This means putting in the hours consistently and also making harder short term decisions for long term benefits
