## Job description

Epsilon3 is a multi-product operations management platform revolutionizing the way teams build, launch, and operate spacecraft and other advanced hardware systems.

Launched in 2021, our company is led by engineers from SpaceX, Google, and NASA, who have experience supporting over 100 space missions. Innovative teams at Blue Origin, Rocket Lab, Axiom Space, Firefly Aerospace, and many others depend on our web-based (SaaS) solutions to plan and track high-stakes procedures. We raised a $15M Series A funding round led by Lux Capital, Y Combinator (YC S21), and other world-class investors.

We're looking for an experienced Senior Account Executive to help drive Epsilon3's next phase of growth. This is a senior individual contributor role for someone who combines an engineering background with a proven track record of selling complex technical SaaS solutions.

You'll own the full sales cycle - from generating pipeline to closing business working directly with technical and executive stakeholders. Success in this role requires technical credibility, consultative selling skills, and a consistent history of exceeding revenue targets.

## Responsibilities

- Own the full sales cycle from prospecting through negotiation and close
- Consistently exceed monthly, quarterly, and annual revenue goals
- Generate approximately 50% of your pipeline through outbound prospecting, networking, and industry events
- Lead discovery sessions and technical product demonstrations with engineering and executive stakeholders
- Develop compelling business cases and communicate customer value across complex buying committees
- Build strong relationships with customers in aerospace, defense, energy, and other technical industries
- Partner closely with Product and Engineering to share customer insights and influence product direction
- Maintain accurate forecasting, pipeline management, and CRM hygiene
- Represent Epsilon3 at customer meetings, conferences, and industry events

Within your first 6-12 months, you will:

- Become an expert in the Epsilon3 platform and target markets
- Build a healthy self-sourced pipeline
- Consistently exceed closed-won revenue goals
- Become a trusted advisor to customers and a key contributor to our growing sales organization

## Basic Qualifications

- 10+ years of quota-carrying B2B sales experience with a history of consistently exceeding quota
- Bachelor's degree in Engineering or another technical discipline
- Professional engineering or hands-on technical work experience prior to transitioning into sales
- Proven success selling complex technical SaaS solutions
- Full-cycle sales experience, including prospecting, technical demonstrations, negotiation, and closing
- President's Club recognition or a demonstrated record of top sales performance
- Experience selling into aerospace, defense, energy, advanced manufacturing, or other engineering-driven industries
- Exceptional communication, presentation, and executive relationship-building skills
- US Citizenship (future security clearance may be required) - must be located in the United States

## Preferred Qualifications

- Experience selling workflow, engineering, PLM, MBSE, simulation, or operations software
- Experience in a high-growth Series B–D SaaS company
- Existing relationships within aerospace, defense, energy, or related technical industries

Why Join Epsilon3:

- Work with industry-leading customers, including NASA and other innovative engineering organizations
- Join at an inflection point with significant growth opportunities
- Sell a highly differentiated product with strong customer adoption and retention
- Partner closely with founders, Product, and Engineering to shape the future of the business
- Play a foundational role in building a world-class commercial organization

Perks:

This full-time role includes stock options, generous PTO, health insurance, and a 4% 401k match.

## Products & Services
- **[Epsilon3 Platform](https://www.epsilon3.io/)**: An AI-powered SaaS platform that covers the entire program lifecycle – planning, manufacturing execution, procedure workflows, testing, data analysis, reporting, risk, document management, and integrations. Includes modules for resource management, BOM/inventory tracking, real-time collaboration, and conditional logic workflows. Supports REST API, pre-built integrations, and on-premise/cloud deployment.

## Competitive Advantages

- Deep domain expertise: Founders and team from SpaceX, NASA, Google, and Stanford; directly understand the pain points of complex operations.
- Adoption by tier-1 customers (NASA, Blue Origin) provides strong social proof and a high barrier to entry.
- Integrates with existing PLM, telemetry, and ticketing systems, and offers on-premise deployment for security-sensitive organizations.

## Strategic Focus
- Continue to scale the platform to serve defense, energy, biotech, and maritime sectors beyond aerospace.
- Deepen AI capabilities for predictive analytics, automated data collection, and intelligent recommendations.

- Fully remote, US-based SaaS startup (with optional hubs in Los Angeles/El Segundo).
- History of supporting over 100 space missions and working with top-tier aerospace and defense organizations.
- Team culture: “engineers from SpaceX, NASA, Google, and Stanford” – emphasis on solving hard problems in a collaborative, high-trust environment.
- Open roles currently include Senior Customer Success Account Manager, Software Engineer, and Senior Product Designer (salary range $120K–$180K for engineering roles).
- Strong funding and revenue growth provide stability, while the small team size (33 people) offers impact and ownership.
