Aerospace & Safety-Critical Engineering
Nubit Solutions helps aerospace, space, defence, and industrial organizations design, certify, and verify software that has to work — every time. Based in Greater Montreal, working across Canada and internationally.
Who We Are
Nubit Solutions Inc. is an engineering services consultancy focused on systems and software engineering, safety-critical aerospace software, and AI adoption for certified engineering organizations. Our work is grounded in 25+ years of hands-on aerospace and embedded systems experience — from turbine engine control systems to DO-178C DAL A certification to satellite payload software programs.
Service AreaBased in Greater Montreal, Quebec. Most engagements are delivered remotely, with on-site visits arranged as needed — across Canada and internationally.

Interim engineering management, distributed team leadership, and measurable process improvement.
Learn more: Program & Engineering LeadershipAI & Machine Learning in Certified Systems
Adopting AI without breaking your evidence chain — and preparing machine-learning functions for certification.
Learn more: AI & Machine Learning in Certified SystemsDirect experience on the programs that matter: turbine engine control, DAL A avionics, and satellite payload software. We measure our work by whether the program moves forward — not by hours billed.
Direct DO-178C DAL A development and certification experience, not just familiarity with the standard.
Director-level program and engineering leadership that stays close to the technical work, not detached from it.
From requirements and architecture through verification and certification liaison, under one accountable team.
Industries We Serve
The same rigor applies whether the platform flies, orbits, deploys, or runs a plant.
We work directly with, and hold training in, the airborne software, systems and safety standards that govern certification. We do not claim DO-254 hardware design expertise; our practice is scoped to systems and software engineering.

The applicant owns the approval, the delegate speaks for the authority, and the supplier owns evidence but no approval. Getting the map straight tells you who to convince and whose signature closes an issue.

The four reviews are scheduled engineering events, not exams. What each one samples, the thread-pull move every reviewer makes, and the failure patterns that repeat on programme after programme.

The assessment chain that decides your software level, why software is assigned assurance rather than a failure rate, and the only legitimate way to change the answer.
