FE Salesforce & AI Engineer, GTM Systems Job Type: Permanent Salary: Competitive + Benefits (DOE) Role Location: US (100% Remote) The Company: We've partnered with a fast-growing med-tech / ad-tech company building AI-powered tools that help pharmaceutical brands reach the right patients and healthcare providers through privacy-compliant, data-driven marketing. They have live AI products already in market, were just named a 2026 Best Places to Work, and are at an exciting inflection point in their growth. The Role: They're hiring a FE Salesforce & AI Engineer, GTM Systems to join a small, high-impact cross-functional team building the internal operating system that powers their go-to-market engine. The team has spent the last year standing up Salesforce from scratch — connecting data sources, integrating systems, and getting the foundational layer in place. They now need someone to come in and build the experience layer on top of it, including AI-powered agent workflows that make the sales team genuinely more effective. This role is ideal for a senior, self-directed engineer who is equally comfortable talking to business stakeholders and writing code — someone who can walk into a room with a sales or RevOps team, understand what they need, and go build it.  What You'll Do * Build custom features, automations, and workflows inside Salesforce using Lightning Web Components (LWC) and Apex, creating a genuine user experience for the sales team * Design and build AI-powered agent workflows using Salesforce AgentForce, Workato Agents, and Glean * Build and maintain integrations between Salesforce and tools like Slack, NetSuite, and internal data systems * Work directly with sales, RevOps, finance, and marketing stakeholders to gather requirements, define solutions, and deliver — without waiting for a detailed spec * Collaborate with existing Salesforce developers and an integration engineer on architecture and implementation * Think strategically about what needs to be built and why — not just execute tickets, but help define the roadmap Ideal Background * 7–10+ years of relevant experience, with a strong track record in Salesforce development and RevOps environments * Hands-on Salesforce development experience — Lightning Web Components (LWC) and Apex are the target; this is a coding role, not an admin role * Demonstrable experience building AI agent workflows — AgentForce, Workato Agents, Glean, or similar platforms; strong personal projects considered given how new this space is * Deep understanding of how RevOps and GTM functions work — you've sat close to sales teams and understand their day-to-day challenges * Experience working in a usage-based or consumption-based pricing environment is a genuine differentiator * Self-starter mentality — you gather your own requirements, talk directly to stakeholders, and deliver independently * Background in ad tech or healthcare is a plus but not required Benefits * Competitive base salary commensurate with experience * 100% remote within the US * Comprehensive benefits package * High ownership role on a close-knit, senior team * Real impact from day one — this is a greenfield build, not a maintenance role * Work at the intersection of Salesforce, AI agent development, and healthcare marketing technology

We are looking for a Head of QA to lead and scale the quality assurance function across all platforms. This role combines strategic leadership with hands-on technical expertise: defining and executing the QA vision, guiding a focused team of 3–4 QA professionals, and driving the adoption of AI-powered testing practices. Whether you are an experienced QA leader or a strong QA Lead ready to step into a head-level role, we would like to hear from you. Our platform supports payment orchestration, compliance automation, and multi-brand gaming operations, where quality is mission-critical. As Head of QA, you will transform the quality function from reactive to proactive, owning the QA organisation end-to-end and ensuring quality is embedded across the entire engineering lifecycle. You will define strategy, lead a small but impactful team, and leverage AI and intelligent automation to establish best-in-class processes that ensure our products consistently meet the highest standards as the organisation grows. Key Responsibilities Quality Strategy & Execution Define and implement the organisation-wide QA strategy, approach, and roadmap. Act as the primary escalation point for QA-related issues, providing risk assessments and mitigation strategies. Oversee test planning, execution, reporting, and root-cause analysis for all releases.

Champion API testing, microservices testing, and end-to-end testing strategies. Evaluate and adopt AI-powered testing tools (e.g., self-healing tests, AI-generated test cases, intelligent test prioritisation). Leverage generative AI for test case generation, defect analysis, and predictive test selection while staying current with emerging AI-in-QA trends. What You’ll Do Inspire confidence through technical credibility and thoughtful leadership. Balance pragmatism with rigour, recognising when “good enough” is appropriate within regulatory constraints. Empower teams to take ownership of quality rather than enforcing it as a separate function. Communicate clearly, manage conflict effectively, and build trust across teams. Measure success through outcomes such as reduced incidents, faster releases, and improved customer satisfaction. What You’ll Bring Experience 4+ years of experience in Quality Assurance, including at least 1–2 years in a leadership or team lead role (QA Lead, QA Manager, or equivalent).
