Senior Account Executive in Cardiff

Join a profitable, well-funded global software company building the backbone of real-time connectivity for modern enterprises. This company is the creator of one of the world’s most widely adopted open-source messaging and data streaming platforms, trusted by developers and enterprises to power mission-critical systems across IoT, industrial automation, energy, automotive, financial services, AI, and event-driven architectures.

With deep roots in open source and a strong engineering-led culture, the platform is used globally to connect, move, and process real-time data across edge, cloud, and hybrid environments. As enterprise demand accelerates and customers increasingly re-evaluate legacy MQTT and messaging solutions, the company is expanding its EMEA sales team with a high-calibre Senior Account Executive to help scale commercial impact across the region.

This is an opportunity to sell true infrastructure software with real technical depth, strong inbound demand, and clear competitive momentum.

The business is seeing strong inbound demand from technically sophisticated buyers, driven by:

• Developer adoption and open-source credibility
• Growing enterprise usage across industrial and regulated sectors
• Increasing dissatisfaction with incumbent messaging and IoT platforms

The challenge is not pipeline. It’s capacity and focus. Senior sales leaders are currently stretched across inbound demand, complex enterprise deals, and customer expansion. This hire adds experienced execution power to:

• Own and progress complex enterprise opportunities
• Proactively engage strategic accounts
• Drive expansion within existing customers
• Help build a repeatable, scalable EMEA sales motion

This is a senior individual contributor role, selling directly to architects, developers, and technical decision-makers inside complex enterprise environments. You’ll own opportunities end-to-end, from early technical discovery through procurement, security reviews, commercial negotiation, and close. This is not transactional SaaS sales. It’s consultative, architecture-led selling into organisations building real-time, event-driven systems. You’ll work closely with product, solutions, and engineering teams in a lean, highly technical sales environment.

• Owning inbound and targeted outbound enterprise opportunities across EMEA
• Engaging deeply technical stakeholders to understand data movement and connectivity requirements
• Navigating complex enterprise processes including security, procurement, legal, and vendor onboarding
• Closing both fast-moving opportunities and longer, multi-stakeholder sales cycles
• Expanding existing customers by identifying new use cases, teams, and regions
• Selling across a growing portfolio including on-prem, cloud, and emerging data movement services
• Acting as a trusted commercial partner to customers building mission-critical systems

• Have experience selling technical, infrastructure-level software
• Are comfortable selling to architects, engineers, and platform teams
• Have owned complex enterprise sales cycles end-to-end
• Understand that deal complexity doesn’t always correlate with deal size
• Have experience expanding accounts after the initial deal closes
• Enjoy operating in lean, build-phase sales teams with high ownership
• Are energised by ambiguity, technical depth, and long-term customer relationships

This role is particularly well suited to candidates from:

• IoT platforms or MQTT ecosystems
• Data streaming, messaging, or event-driven platforms
• Real-time data infrastructure or data movement technologies
• Open-source or developer-led product environments
• Experience with adjacent technologies such as Kafka, event streaming, or distributed data platforms is also highly relevant

Role covers EMEA, with flexibility on location. Fully remote opportunity United Kingdom or Germany preferred, other European locations also possible. Additional European languages (French, Spanish, Italian) are a strong advantage. Collaborative, international working environment. Low-ego, execution-focused culture with strong technical leadership.

• Sell Something Real: Infrastructure software used in production at global scale
• Technical Credibility: A platform developers genuinely trust and adopt
• Enterprise Momentum: Growing traction across industrial and regulated sectors
• High Ownership: Shape how EMEA revenue scales, not just run a patch
• Start-up Agility, Real Substance: Profitable, well-funded, and product-led
• Career Leverage: Exposure to complex deals, expansion, and strategic accounts

If you’re an experienced technical Account Executive who enjoys selling complex infrastructure, working closely with engineers, and making a tangible impact in a growing region, this is a role worth exploring.
