Mechanical Engineer – Field Integrations 

What You Will Do (key responsibilities for this role include but are not limited to): <ul><li>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&amp;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. </li></ul><ul><li>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. </li></ul><ul><li>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. </li></ul><ul><li>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. </li></ul><ul><li>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. </li></ul><ul><li>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.  </li></ul><ul><li>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. </li></ul><ul><li>Continuous improvement: Keep improving the team’s templates, checklists, review standards, and tooling, and feed lessons from each project back in. </li></ul>What You Will Bring: <ul><li>Degree in an engineering discipline; Mechanical or Chemical/Process strongly preferred. </li></ul><ul><li>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. </li></ul><ul><li>All-rounder technical fluency — you can read and challenge work across P&amp;IDs, piping isometrics, equipment datasheets, SLDs, general arrangements and layouts, structural calculations, and I&amp;C/control diagrams, even where it isn’t your primary discipline. </li></ul><ul><li>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. </li></ul><ul><li>Track record of building, growing, and retaining engineering teams. </li></ul><ul><li>Experience delivering large-scale capital projects (&gt;25 MUSD) in energy, power, oil &amp; gas, chemicals, or heavy industrial. </li></ul><ul><li>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”. </li></ul><ul><li>Comfortable surfacing problems early, including ones you own. You’d rather have an awkward conversation now than a worse one later. </li></ul><ul><li>Bias to action — you start on what obviously needs doing without waiting to be asked, and bring people along rather than going around them. </li></ul><ul><li>Curious quick learner with strong analytical and problem-solving skills; entrepreneurial and self-motivated. </li></ul><ul><li>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. </li></ul><ul><li>Passion for safety and environmental stewardship. </li></ul><ul><li>Fluent in English (written and spoken); Spanish or other languages a strong plus. </li></ul><ul><li>Valid driver’s license. </li></ul>Bonus Points! <ul><li>Background in industrial process plants — anything from Oil &amp; Gas and petrochemicals to biomass, CSP, or combined-cycle power. </li></ul><ul><li>Prior experience building or scaling an engineering team from a small base. </li></ul><ul><li>Experience in a fast-paced start-up environment deploying novel technologies at large scale. </li></ul><ul><li>Familiarity with international project codes (ASME, API, EN, IEC) across multiple jurisdictions. </li></ul>What We Offer: <ul><li>Comprehensive Medical Benefits</li><li>Very competitive salary plus equity in a quickly-scaling company</li><li>Opportunity to impact industrial carbonization on a daily basis</li></ul>This role is hybrid in Madrid and necessitates being on-site at our projects internationally as required for the success of the project.
