What You Will Do (key responsibilities for this role include but are not limited to): 

• Technical leadership across disciplines: Act as the senior technical reviewer for the Project Engineering team’s deliverables. You’ll be comfortable across mechanical, process, structural, electrical and I&C work — even where it isn’t your primary discipline — and you’ll set the bar for what’s good enough to leave the team. 

• Engineering process and quality: Define and own how technical work gets done in Delivery — review gates, drawing and specification checklists, technical bid evaluations, vendor data review, and lessons-learned loops. The bar is that the team’s output looks the same regardless of who produced it. 

• Project execution support: Partner with Project Managers as the senior engineering counterpart on live projects — unblocking technical decisions, escalating risks early, supporting client and authority reviews, and making sure engineering deliverables land on time, in scope, and at the right quality. 

• Vendor, EPC, and customer engineering: Lead engineering interactions with EPC partners, OEMs, and customer engineering teams. Review their submissions critically, hold them to spec, and stay engaged through to resolution when things aren’t right. 

• People leadership and team building: Lead a multi-discipline team of Project Engineers. Your job is as much to grow them as it is to deploy them — set clear expectations, give honest feedback, and recruit what the team is missing. 

• Cross-functional interface with HQ: Act as the Delivery team’s primary engineering interface with Product/Design at HQ — translating field learnings into product input and product changes into delivery-ready engineering.  

• Safety, compliance, and standards: Make sure projects meet applicable industry codes, regulatory requirements, and Rondo standards, and that safety is treated as foundational during the different project engineering phases. 

• Continuous improvement: Keep improving the team’s templates, checklists, review standards, and tooling, and feed lessons from each project back in. 

What You Will Bring: 

• Degree in an engineering discipline; Mechanical or Chemical/Process strongly preferred. 

• 10+ years of total experience, including 7+ years of hands-on engineering on large industrial, energy, or process plants and 3+ years line-managing engineers. 

• All-rounder technical fluency — you can read and challenge work across P&IDs, piping isometrics, equipment datasheets, SLDs, general arrangements and layouts, structural calculations, and I&C/control diagrams, even where it isn’t your primary discipline. 

• You still enjoy the technical work itself: red-lining a drawing, writing a clean specification, pushing back on a vendor with data. Not just managing the people who do. 

• Track record of building, growing, and retaining engineering teams. 

• Experience delivering large-scale capital projects (>25 MUSD) in energy, power, oil & gas, chemicals, or heavy industrial. 

• Strong leadership, communication, and negotiation skills. Comfortable being the most senior engineer in the room, and equally comfortable saying “I don’t know — let’s find out”. 

• Comfortable surfacing problems early, including ones you own. You’d rather have an awkward conversation now than a worse one later. 

• Bias to action — you start on what obviously needs doing without waiting to be asked, and bring people along rather than going around them. 

• Curious quick learner with strong analytical and problem-solving skills; entrepreneurial and self-motivated. 

• Flexibility to work across multiple time zones (Australia east coast through U.S. west coast) and travel internationally to project sites and HQ as required. 

• Passion for safety and environmental stewardship. 

• Fluent in English (written and spoken); Spanish or other languages a strong plus. 

• Valid driver’s license. 

Bonus Points! 

• Background in industrial process plants — anything from Oil & Gas and petrochemicals to biomass, CSP, or combined-cycle power. 

• Prior experience building or scaling an engineering team from a small base. 

• Experience in a fast-paced start-up environment deploying novel technologies at large scale. 

• Familiarity with international project codes (ASME, API, EN, IEC) across multiple jurisdictions. 

What We Offer: 

• Comprehensive Medical Benefits
• Very competitive salary plus equity in a quickly-scaling company
• Opportunity to impact industrial carbonization on a daily basis

This role is hybrid in Madrid and necessitates being on-site at our projects internationally as required for the success of the project. The estimated annual salary range for this role is TBD and it would be eligible for Rondo’s excellent benefits listed above plus additional compensation in the form of equity. Please note that some pay bands may have wide ranges of compensation to accommodate candidates’ diverse sets of skill levels and experience.
