Ramzi Marjaba is a seasoned Solution Engineer and consultant currently with Veeam Software, working remotely from Ottawa since March 2025. Prior to this, he spent nearly four years as a Senior Solution Specialist at Keysight Technologies, managing Eastern Canada accounts and mentoring both SEs and account executives. Earlier in his career, he held technical roles at Spirent Communications, Alcatel‑Lucent, and Nortel, starting as an embedded software tester and evolving into a network design engineer and systems engineer.

In 2018, Ramzi founded We the Sales Engineers, a coaching platform and podcast designed to help sales engineers grow through thoughtful conversation, expert mentorship, and practice‑based learning. With hundreds of episodes and written content to his name, he’s built a global community for pre‑sales professionals seeking to sharpen their craft.

Ramzi emphasizes the difference between treating symptoms versus diagnosing root business needs—with a heavy focus on discovery, customer context, and vision building. He often compares SEs to business athletes: they don’t get to practice outside the field, and must deliver under pressure with clarity and impact. He also explores the evolution of presales roles in a shifting job market, noting the increasing competitiveness and need for strategic, value‑centered hiring.

Outside of client work, Ramzi mentors aspiring SEs, runs podcast and written series, and leads workshops—from quick discovery techniques to advanced whiteboarding and objection management.

Sam Holland is a mechanical and product design engineer whose journey threads through influential design labs and breakthrough products—from MakerBot’s pioneering 3D printers to livestream hardware at Vimeo, and now forging his own path through Informal.cc. At MakerBot, he served as Technical Lead on the Method 3D printer and spearheaded subsystems for the Replicator Z18, work that included patent‑winning innovations in gantry mechanics and extruder design. His move to Livestream and Vimeo saw him shaping products like Mevo Plus and Studio One, integrating sleek form and functionality for the live‑streaming era.

In late 2018, Sam co‑founded Informal.cc in Brooklyn—a freelance collective dedicated to helping startups design, manufacture, and market hardware effectively. There, he blends expertise in CAD (OnShape, SolidWorks), design for manufacturing and assembly, vendor sourcing, and team staffing. Under his leadership, Informal has also launched the Informal Hardware Handbook, a community‑driven guide that chronicles best practices across ideation, manufacturing, and go‑to‑market strategy—rooted in real‑world experience navigating constraints like chip shortages and shifting product timelines.

Beyond the drafting table, Sam brings products to life—some have reached audiences through QVC, CVS, Best Buy, and even Shark Tank. He couples doing with teaching, from presenting hands‑on hardware workshops at schools like Rock Point in Vermont to authoring product teardowns and insights on Informal’s blog—most recently a teardown of a SimpliSafe Keypad and a love letter to OnShape as his “ride‑or‑die” CAD tool. Outside of engineering, he balances his design drive with drumming, cooking, and Vermont explorations.

Here’s a conversation with Sam Holland, where we’ll dive into accelerating hardware careers, cracking the design‑to‑manufacturing code, and even that hilarious “Donut Hole‑Der” open letter to Dunkin’—because sometimes even frameworks for product engineering aren’t spared a sense of humor.

Duann Scott is a globally recognized leader in computational design, additive manufacturing, and the emerging intersection of software and fabrication. With a background in industrial design and a PhD research foundation from the University of South Australia, Duann launched BITS to ATOMS in 2009 to explore how digital tools would revolutionize product design and manufacturing. What started as an academic pursuit quickly transformed into a dynamic industry journey through some of the most innovative companies in the space.

At Shapeways, he helped build one of the first online 3D printing communities. At Autodesk, he shaped the strategy for the $100M Spark investment fund and led the acquisition of Netfabb, now integral to Autodesk's digital manufacturing suite. At nTopology, Duann served in multiple executive roles, driving growth and expanding the company’s software integrations for advanced manufacturing applications.

In 2021, he relaunched BITS to ATOMS as a consultancy and launched CDFAM, the Computational Design Symposium Series. CDFAM now brings together cutting-edge thinkers across engineering, software, and architecture at events in NYC, Berlin, and Brooklyn. Whether supporting MIT xPRO students, contributing to the Wohlers Report, or guiding the 3MF Consortium as Executive Director, Duann is committed to building better tools, workflows, and communities around computational manufacturing.

Beyond his professional pursuits, Duann brings a creative edge from his past life as a musician and designer, continually pushing the boundary between art and engineering. His mission? To create a better digital thread from bits to atoms.

Tessa Axsom blends deep mechanical engineering know‑how with the craft of product marketing. Today she serves as Product Marketing Manager – CNC at Fictiv, the on‑demand manufacturing partner known for its robust CNC resources and design guides. In this role, she translates shop‑floor realities into crisp messages, actionable guidance, and programs that help engineers build better parts faster. Before moving into marketing, Tessa wrote extensively for Fictiv’s Resource Center, authoring practical articles on topics like drawing best practices, corrosion vs. oxidation, and developing people skills as an engineer.

Her path began at Purdue University in mechanical engineering and wound through metallurgy and aerospace, including design of aluminum plate‑and‑fin heat exchangers and quality leadership in chemical analysis labs. That blend of materials, design, and operations experience anchors her marketing perspective in real constraints: tolerances, surface finish, manufacturability, and supplier capability—especially in CNC machining.

Beyond the written word, Tessa shows up as an educator and voice in the community. Fictiv has featured her in webinars and industry conversations, from manufacturing complex designs to commentary on timely topics. She also runs Precision Pen & Quality, where she applies engineering rigor to technical communication and consulting.

Across all of it, Tessa advocates for a simple idea: engineers who can communicate—who can frame tradeoffs, tell a crisp story, and align stakeholders—ship better products. That’s why her work on people skills for engineers resonates so strongly with our audience of builders and problem‑solvers.
