Your Impact

Imagine the year 2030. Advanced technology has automated routine tasks to put Police Officers back in the community, dramatically improving the quality and safety of our lives. Artificial Intelligence connects the dots and surfaces insights to help prevent crime and keep officers and citizens informed and protected.

Today, public safety officers spend up to 40% of their time on the job filling out paperwork. Not only is this tedious for officers, but the never-ending pile of paperwork reduces the amount of time they can spend out in the field, protecting their communities. That's why we're building Axon Records — a cloud-native web platform that cuts down on paperwork so that officers can spend more time prioritizing the safety of their communities.

As a Sr. Fullstack Engineer on the IRS Vietnam team, you will own features across the entire stack — from React-based UI to GraphQL APIs and Go microservices — and contribute directly to expanding Axon Records to international law enforcement agencies in the US, Australia, and the UK. You will help shape how the platform handles complex, country-specific reporting requirements at scale.

This is a high-impact role with opportunities for technical leadership and cross-team influence.

Work Location: This role is based out of our Ho Chi Minh Office and follows a hybrid schedule. We rely on in-person collaboration and ask that team members work onsite Tuesdays through Fridays, with the flexibility to work remotely on Mondays, unless there is an approved workplace accommodation. We believe that connection fuels innovation, and our in-office culture is designed to foster meaningful teamwork, mentorship, and shared success.

• 💼 Revenue team 
• 📍 Vietnam
• 🕜 Full-Time Remote
  
• 🌐 Fluent in English and Vietnamese 

What you will do
You’ll be the face of Lighthouse for prospective clients, owning the full sales cycle from prospecting to close. This is a hunter role: you carry a quota, you build your own pipeline, and you’re accountable to outcomes and success. No excuses, just results.
What makes this different: you won’t do it alone. Lighthouse is deploying an agent AI infrastructure — Enablement, Pre-Sales, and Coaching agents — alongside a modern revenue stack. AI handles the prep, the sequencing, and the pattern recognition so you can focus on what matters — building relationships, running sharp discovery, and closing deals.
We work with structured sales methodology, like MEDDPICC to support high-quality deal execution. You’ll advance deals with evidence, protect pricing on value, and forecast with precision. We want to help you use modern tools to become a better seller and achieve great success. 

Where you will have impact

• Own your territory and your number. Build and execute a strategic territory plan to generate a net-new pipeline. Maintain 3x pipeline coverage, forecast honestly, and take full accountability for your results. Your quota is your commitment.
• Hunt and build a pipeline. Source a meaningful share of your own pipeline through outbound sequences, ICP targeting, Lighthouse Connect events, and industry conferences. This is not an SDR-reliant role.
• Run a disciplined sales process. Using MEDDPICC to qualify and advance opportunities. Use the AI Pre-Sales Agent to identify gaps before every major call. Advance deals through stage gates with evidence, not optimism. Leverage AI to make your days easier and focus on more selling time.
• Use AI as a force multiplier. Leverage the Enablement Agent for call prep, discovery frameworks, and positioning. Use the Coaching Agent to surface patterns in your pipeline and win rate. Push back on the tools when they’re wrong — help make the system smarter.
• Become a hospitality expert. We will help you understand revenue management workflows well enough to run ROI conversations without a pre-sales overlay on every deal. Position an integrated platform versus point solutions. Know the competitive landscape inside out.
• Drive results beyond net-new. Consistently meet and exceed sales targets through new business and by identifying expansion and upgrade opportunities within your accounts. Partner with Product to share market feedback and influence the roadmap. Represent Lighthouse at industry events to build the brand and your

About our team

You’ll join a global Revenue team of 150+ sales professionals across 24 countries. Our team works across the full Lighthouse product suite, helping hotels, chains, and hospitality groups achieve their commercial goals. It’s a collaborative, high-energy environment with real opportunities for career growth and the chance to learn from experienced leaders as we continue to expand our market share.

What's in it for you

• Flexible time off: Autonomy to manage your work-life balance.
• Career development: Workshops, frameworks, and training to maximize your professional potential.
• Impactful work: Shape products relied on by 85,000+ users worldwide.
• Referral bonuses: Earn rewards for bringing in new talent.

Who you are

• 2–5 years in a closing sales role, SaaS experience is a must but hunger and skill matters more than industry tenure.
• Self-directed, coachable, and driven to continuously improve. You seek feedback on your calls, your pipeline, and your positioning — and act on it within the next deal, not the next quarter.
• You treat AI tools as a core part of your selling motion, not a novelty. You adopt new tooling quickly and bend it to your style.
• Experience with MEDDPICC or similar qualification frameworks is a plus, not a requirement. What matters is that you bring discipline and structure to how you run deals.
• Strong business acumen with the ability to sell on value, not price. Confident engaging stakeholders from GMs to C-suite.
• You want to win. You prospect when it would be easier not to. You follow up one more time. You’re not okay with a bad quarter.

We hire for mindset first, technology second. To succeed here, you need:

Engineering Skills

• Our Tech Stack: We primarily use Golang and Node.js on the backend and PostgreSQL for our database. But we are open to any background (Java, Python, PHP, etc.)—we care about your logic, foundation, and problem-solving skills more than the specific language.
• Critical Thinking: You don't just fix bugs; you find the root cause. You proactively think about edge cases, database bottlenecks, and security before you write code.
• System Design (For Seniors): You understand how to design complex systems (Distributed systems, Databases) and can explain your choices clearly. You can design systems that stay fast even when traffic increases by 10x.

Product Mindset

• User Focus: You understand that code is a tool to solve user problems. You care about the quality of the product, not just the quality of the code.
• Curiosity: You ask "Why?" Why are we building this? Is there a simpler way? How does this help the business?

Collaboration

• Ownership: You own your work, learn from mistakes. You don't wait for detailed instructions; you talk to the PM, understand the requirement, and deliver the solution.
• Communication: You can explain technical problems to non-technical people (like Designers or other stakeholders) clearly and respectfully.
