Join Acuity Insights’ startup-to-scaleup journey as a Senior Software Developer. In this fully remote role, working within EST and PST time zones from anywhere in Canada, you’ll be part of a team modernizing our assessment platform, Casper. You’ll build new systems, maintain existing systems, lead design, and mentor developers.
Our core assessment product, Casper, provides education programs with a more holistic view of applicants by evaluating their soft skills. Incorporating Casper's insights into the admissions process results in a larger applicant pool, enables student success, and graduates better professionals. Since 2014, Casper has been adopted by over 600 higher education programs, and more than 1 million applicants have registered to take the test.

The role is ideal for a quality-focused full-stack developer with strong technical proficiency who is looking to advance their career with a people-centric company that prioritizes work-life balance, invests in continuous growth, and builds products with meaningful social impact.

Prior Labs is building foundation models for structured/tabular data – AI's biggest blind spot. While LLMs handle text/images, tables (numbers, categories, text mix) need native understanding. Our approach, TabPFN (published in Nature, 1M+ downloads, 3k+ GitHub stars), uses transformers pre-trained on synthetic data to achieve state-of-the-art results on small datasets zero-shot.
We're tackling a $100B+ opportunity to transform data science, finance, healthcare, and science. Backed by €9M pre-seed from Balderton, XTX Ventures, and leaders from Hugging Face, DeepMind, etc.
We're hiring a founding team to build this new category:
Software Engineer: Build scalable infra & APIs. Data Scientist / ML Engineer: Optimize & scale our TFMs. Product Manager: Define the vision for AI-native tabular tools. Developer Relations: Grow our community & drive adoption. Location: On-site in Berlin or Freiburg (we build together). Offer: Competitive salary + significant equity. Shape the future of AI for structured data from day one.
