The company is on a mission to transform how engineering organizations detect and solve bugs, leveraging cutting-edge AI to make the development process faster and smarter.
This is not just another engineering role — it’s an opportunity to join as a founding team member, shape the product vision, and influence the technical direction from day one. You’ll work on building a production-ready MVP out of a working proof of concept and lay the foundation for a scalable platform.

You’ll take ownership of the backend architecture, work closely with the founding team, and turn complex ideas into elegant, production-ready systems.

What you’ll do

  • Build and optimize backend systems to power an AI-driven platform
  • Transform a proof of concept into a robust, scalable MVP
  • Collaborate with the founding team to define product and technical strategy
  • Take full ownership of features and deliver in a fast-paced startup environment

What you bring

  • 10+ years of overall engineering experience
  • 4+ years of Python development
  • Strong backend development skills and experience building production-ready systems
  • Ability to work independently and thrive in a fast-paced, dynamic environment
  • Excellent communication skills and a team-player mindset
  • Spoken English B2

Bonus points if you have

  • Experience building systems powered by LLMs
  • Knowledge of DevOps and cloud infrastructure
  • Familiarity with multiple programming languages (Java, C, C++, JavaScript, TypeScript)

Benefits

  • Work in a highly professional team with a friendly community spirit and supportive environment
  • ‍Paid vacation — 20 business days per year, 100% sick leave payment
  • Flexible working hours – we care about you (!) and your output
  • 5 sick days per year
  • Equipment provision
  • Health insurance in Luxmed (after the end of the probationary period)
  • Partially compensated educational costs (for courses, certifications, professional events, etc.)
  • Legal and Accounting support in Poland
  • English and Polish classes 2 times a week (online)
  • Bright and memorable corporate life: corporate parties, gifts to employees in honor of live events, weekly pizza Fridays

About On The Spot Development

View company profile

At the heart of On The Spot Development lies a culture born from a desire to fix a broken system. The company's journey began with a sense of frustration. After years in the software development industry, its founders repeatedly witnessed a disheartening pattern: companies seeking to build and grow their products through outsourcing were consistently let down. They were tired of seeing the promise of senior expertise result in junior developers, of navigating confusing and opaque pricing models, and of watching teams get constantly shuffled. The consequences were rushed timelines, poor code quality, and unclear communication, turning the exciting process of software development into a stressful and painful experience.

This deep-seated dissatisfaction was the catalyst for creating a different kind of company. On The Spot was founded in 2016 with a clear mission: to create a development partner where these pervasive problems simply wouldn't exist. The core of their philosophy is building genuine, long-lasting relationships with clients. They achieve this by connecting companies with top-tier local talent who become fully integrated, dedicated members of their clients' R&D teams. This model fosters a sense of ownership and commitment that is often lost in traditional outsourcing. Transparency is another cornerstone of their culture, with clear, straightforward pricing and no hidden costs. This approach stands in stark contrast to the industry norms they set out to change. They don't just provide a service; they build a community where engineers can develop their skills, share knowledge, and connect with like-minded professionals through initiatives like their 'TechSpot' events and '137 Podcast', fostering a vibrant and supportive engineering culture.
