Senior product engineer

Newcastle Upon Tyne (Tyne and Wear)
Colossal
Product engineer
Posted: 11h ago
Offer description

Founded by Paul Anthony, creator and co-founder of Primer (Series B, $425M valuation), Colossal is building at the intersection of generative app development and commerce infrastructure. Think: Lovable for commerce, but for non-developers.


We're backed by Tier 1 investors: Seedcamp, 10x Founders, Connect Ventures, and are planning to raise our seed round later this year.


Why Colossal?

The digital goods market is projected to rise to $400+ billion by 2030, with some segments experiencing double and triple digit growth. The software landscape is rich with tools and services to help businesses build their ideal commerce solutions, but these are fragmented and demand deep knowledge of the commerce value chain to get the most out of.


We’re building an ambitious new platform for digital goods sellers to craft their ideal commerce experiences for their unique customer base. We’re still in stealth mode, so get in touch to learn more. 🥷


What we’re looking for

* 5+ years experience building service-based software products end to end, ideally at early-stage startups
* Generalist mindset with experience across the full stack
* Strong understanding of CI/CD, cloud infrastructure, observability, and developer tooling
* Comfortable owning products and features end to end, and taking responsibility for performance and optimisation
* Strong communicator, able to distribute knowledge across the team effectively through documentation, talks, demos and presentations
* A current understanding of AI-based tools, methods and paradigms
* Familiar with “app store” paradigms and development frameworks (bonus if in commerce), and know what good looks like from a developer experience standpoint


What you’ll do

* Build and own core backend services for our commerce infrastructure tools, including billing, workflows, and financial operations
* Build features that integrate generative AI into real world product experiences
* Play a key role in software architecture design, including research, writing POCs for further refinement
* Implement Figma-based designs, motion and UX with precision


How we hire

* Initial call with the founder (30 mins)
* Complete a take home exercise
* Task review and pair programming with a team member (1 hour)
* Meet with the product team for 2-way interview (30 mins)
* Offer stage (including reference checks)
