The Opportunity
We’re looking for a Content & Communications Strategist to join our Marketing & Communications team, reporting directly to the Head of Marketing & Communications. This is a rare opportunity to help shape the public voice of a fast‑scaling, deeply technical company operating at the frontier of engineering and AI.
In this role, you’ll translate complex, high‑value work into clear, compelling narratives across every channel where PX shows up — the website, social platforms, events, executive stages, partner channels, and internally. You’ll collaborate closely with engineers, product leaders, partner teams, leadership, and designers to turn our work into stories that build credibility, attract talent, and deepen customer engagement and confidence.
We're looking for someone who thrives at the intersection of storytelling, creative execution, and strategic alignment. You will operate as a core part of PX’s comms engine, helping build a scalable content operation and raising the creative bar across everything we publish.
We operate in a fast‑moving, high‑stakes environment where priorities can shift quickly and the path isn’t always linear. As we grow the team, you’ll be one of the core operators driving content delivery — which means real ownership, real impact, and real learning. If you thrive under pressure, enjoy solving problems on the fly, and like stretching beyond your comfort zone, you’ll feel at home at PX.
What You’ll Do
- Partner with the Head of Marketing & Communications to develop and maintain a unified editorial calendar across blog, website, social, events, and PR moments.
- Write and edit high‑quality content — blog posts, web pages, one‑pagers, long‑form thought leadership, scripts, and event materials — that reflects PX’s tone of voice and raises the signal across all channels.
- Support the development of messaging and materials for executive and technical speaking engagements.
- Lead PX’s voice on LinkedIn and Instagram, sourcing content, shaping narratives, and publishing a consistent drumbeat of high‑signal updates, helping amplify key moments across product, platform, partnerships, and talent.
- Ensure stylistic consistency and creative excellence across all digital touchpoints.
- Collaborate with internal teams and external agencies on the creation of video content — storyboarding, scripting, production, and review.
- Support internal communications and employer brand storytelling (#comms announcements, people‑related updates, talent events, and recruiting content).
- Partner with Talent to support employer brand storytelling, creating compelling content that attracts world‑class engineers and researchers.
- Work with partner organizations to produce and amplify joint content, case studies, and announcements.
- Uphold and evolve PX’s tone of voice and editorial standards across all communications.
- Track performance through comprehensive dashboards, gather qualitative and quantitative insights, and continuously refine what great looks like.
What Success Looks Like (First 90 Days)
- Develop a PX‑specific content strategy grounded in our positioning, technical domain, and target audiences, with clear priorities, themes, and a structured editorial plan.
- Publish 4‑6 high‑quality blog posts that meet PX editorial standards (clear thesis, strong narrative, technically grounded, visually supported), supported by short‑form video content for social amplification.
- Own and maintain a clean, reliable editorial calendar used by the wider team.
- Deliver event and executive materials end‑to‑end (slides, talking points, social), ensuring they’re on‑brand and engaging.
- Build strong working relationships with engineers and technical stakeholders, proactively sourcing stories and insights.
- Demonstrate clear understanding of PX’s positioning, customers, competitors, and technical domain.
About You
- 5‑6 years of experience in communications, marketing, or editorial roles (agency or in‑house), ideally within B2B tech, AI, engineering, or deep‑tech environments.
- Exceptional writer and editor with the ability to distill technical concepts into accessible, incisive stories.
- Strong narrative and tone of voice instincts — you know what makes a story compelling and how to adapt it for different audiences and formats, while staying true to the company/stakeholder tone of voice.
- Comfortable working cross‑functionally with engineers, designers, technical leaders, and commercial teams.
- High‑agency, proactive, and comfortable with ambiguity; you can drive projects forward with minimal oversight.
- Strong judgment and discretion, able to handle sensitive information and high‑stakes content.
- You operate with high ownership and motivation — you don’t wait to be told what to do.
- You don’t compromise on quality or level of attention to detail, regardless of the format you’re working with.
- You are comfortable working at pace and flexing when needed.
- You are excited to engage deeply with technical material, not just simplify it.
- You can develop PX‑specific content strategy grounded in our technical domain, customers, and positioning — not templated frameworks.
- You demonstrate editorial judgment: identifying what’s new, what’s redundant, and what’s worth saying.
Bonus Points
- Experience supporting executives with talks, presentations, and event materials.
- Familiarity with visual design workflows (Figma, Adobe Suite) or working closely with design teams/agencies.
- Experience working with or around video production.
This role is the right fit if
- You do your best work when you have ownership and room to shape things, rather than waiting for a fully formed brief.
- You’re genuinely comfortable — maybe even energized — by complex technical subject matter, and you know how to get up to speed fast.
- You use AI as a tool to streamline projects and sharpen your thinking, not as a substitute for it.
- You’re flexible about how and when you work, and you take deadlines seriously.
- You hold yourself to a high standard and actively look for ways to raise the bar on your own output.
