Logo Designer Needed for Structural Engineering SaaS Platform

I’m looking for a professional graphic/logo designer to refine and formalise an existing logo concept for a structural engineering software platform. The software is focused on: reinforced concrete section analysis structural design engineering visualisation technical engineering workflows The branding should feel: premium technical modern minimal engineering-focused trustworthy/professional high-end SaaS quality I already have an initial concept/logo draft (attached), but I need a designer to elevate it into a polished production-quality brand package. Existing Logo Concept The current logo concept is based on a reinforced concrete cross section and should retain that engineering meaning. The icon currently includes: a concrete section outline reinforcement bars in the corners a diagonal dashed line representing a neutral axis / strain plane blue + black colour styling The refined logo should better represent: reinforced concrete behaviour compression/tension zones structural analysis concepts engineering precision For example: subtle compression block styling/gradient cleaner representation of strain or neutral axis refined RC detailing aesthetic premium engineering visual language I do not want the logo to become overly abstract or generic tech branding. It should still feel recognisably related to structural engineering and reinforced concrete design. Design Direction The current blue/black theme works well and should generally remain within that direction, however I want professional exploration of: blue + charcoal palettes navy + graphite palettes subtle gradient variations flatter/minimal versions modern SaaS typography premium engineering software styling The designer should also propose a cohesive colour palette suitable for: the logo website UI dashboards buttons/highlights dark/light themes The final branding direction should align with a professional engineering SaaS platform rather than a construction company. Examples of qualities I like: clean vector geometry minimal but meaningful symbolism professional typography modern technical branding subtle depth/gradient rather than flashy effects Scope of Work Please: refine the existing logo concept improve typography/font selection improve icon proportions/alignment test multiple font options refine the reinforced concrete section graphic improve compression block / gradient treatment create cleaner white-background versions create modern SaaS-ready branding variations provide several polished concepts/options Deliverables Required Final deliverables must include: SVG PDF AI / editable source files PNG exports transparent versions white background versions favicon/app icon versions horizontal and stacked layouts monochrome versions social/profile icon variants Please also provide scalable versions suitable for: website mobile app documentation engineering reports presentations print Proposal Requirements Please include: examples of previous logo/branding work any SaaS or engineering-related branding examples estimated turnaround time revision rounds included Potential for future UI/branding/design work if the result is strong.
