ABOUT JAMPACK



Wholesale is 7x the size of e-commerce, yet the infrastructure is stuck in the 1990s. We're building the agentic operating system for wholesale that replaces spreadsheets, email chains, and manual data entry with autonomous workflows that just work. We recently raised a $3.2M seed round led by Maveron.



Jampack already powers high-growth brands like Fishwife, Immi, and PATH — handling everything from purchase order ingestion to freight coordination to invoicing and payment reconciliation.



We're a small, high-agency team building what doesn't exist yet.




THE ROLE



Our forward deployed team is how we turn a signed customer into one who can't imagine operating without us. As a Forward Deployed Engineer, you sit at the intersection of engineering, operations, and customer partnership — embedding directly with CPG ops teams to map how their wholesale operation actually runs, then making Jampack run it.



This role is for someone who thrives in ambiguity, moves fast, and is genuinely curious about hard operational problems. You'll own the implementation lifecycle from kickoff through go-live — and you won't just configure the platform, you'll extend it.




WHAT YOU'LL DO


 - Own customer onboarding end to end — discovery, integration, configuration, testing, and go-live — across our growing CPG customer base

 - Embed with operators to map their full purchase-order-to-cash workflow, surface requirements, and design the right setup on Jampack

 - Build and troubleshoot the integrations that make it all work — across EDI, ERP and inventory systems, accounting, and freight

 - Translate messy, real-world operational requirements into clean data models, configurations, and new product capabilities

 - Be the technical bridge between customers and engineering — turning what you learn in the field into a sharper product
   


WHAT WE'RE LOOKING FOR


 - 3+ years in forward deployed, solutions, or implementation engineering, technical onboarding, or a similar customer-facing technical role (CPG, supply chain, logistics, or ERP/integrations experience is a big plus)

 - Technical from first principles — comfortable with APIs, data models, SQL, and debugging integrations; you can read and write code when you need to

 - A systems thinker who can untangle interconnected people, process, and technology problems and put them back together with clarity

 - You thrive in ambiguity, move fast, and take ownership of outcomes — not just outputs

 - You care about the problem as much as the technology

We're a small, high-agency team building what doesn't exist yet.



THE ROLE


We're hiring a founding engineer to build the core platform that powers our AI agents and our customer experience — the data pipelines, integrations, APIs, and operator console that make everything work.

The moat isn't the model. It's the scaffolding — the software infrastructure around the AI that connects to real-world systems and delivers real-world reliability. That's what you'll build.




WHAT YOU'LL DO


 - Take customer-facing features from concept to production. You'll talk to users, design the solution, build it, and watch them use it.

 - Design secure, auditable data models and event-driven pipelines that power our agent workflows

 - Develop internal and external APIs and a real-time operator console that gives customers full visibility into their operations

 - Build first-party integrations with ERPs, 3PLs, retailers, and freight partners — and a resilient sync layer that keeps everything in lockstep

 - Establish observability, SLOs, and on-call practices for mission-critical workflows where downtime means missed shipments and chargebacks

 - Work across the full stack — backend, data engineering, and frontend — wherever the highest-leverage problem lives
   


WHAT WE'RE LOOKING FOR


 - 5+ years building production platforms or infrastructure at scale (startup experience preferred)

 - Strong proficiency in TypeScript/Node, Postgres, queues/streams, and cloud platforms (AWS/GCP)

 - Systems thinking paired with product intuition — you care about the developer experience and the operator experience equally

 - Versatility across backend, data engineering, and frontend. You don't wait for someone else to build the other half

 - You want to work on hard infrastructure problems that have direct, measurable impact on real businesses

Max Retail · Fractional engagement with a path to a full-time VP of Sales & Marketing role About Max Retail Max Retail is a cutting-edge technology platform enabling independent retailers and brands to sell their excess inventory online effortlessly. Our mission is to become the largest supply chain that holds no inventory, providing a seamless connection between supply and global demand. The Engagement Max Retail has an established revenue operation, proven sales playbooks, and the rev ops infrastructure and systems to support them. We are looking for a senior sales and marketing leader to optimize and scale the demand engine for the supply side of our marketplace, the independent retailers who supply inventory. This role is structured as a fractional engagement to start, with a clear path to a full-time VP of Sales & Marketing role for the right person. What You'll Do (Fractional Scope) Develop product-led growth. Build product-led acquisition and activation motions that reduce customer acquisition cost and shorten time-to-value on the supply side of the marketplace. This is a hands-on engagement. You will execute directly in the channels and work alongside our marketing, sales, and rev ops teams, not direct from the sidelines. Optimize our existing acquisition channels. Take the channels already driving supply (independent retailer) acquisition and improve their volume, performance, conversion, efficiency, and cost measured against CAC, LTV, and payback by channel. Identify and create new channels. Find, test, and stand up net-new acquisition channels on supply, validating each against the same economics before scaling. Own organic and AI-era discovery. Set the organic discovery strategy across SEO, generative engine optimization (GEO), and answer engine optimization (AEO), so that Max Retail remains discoverable across both conventional search and emerging AI-driven platforms. Align with the existing sales motion. Partner with the sales and customer success teams to ensure the demand engine feeds a qualified, well-routed pipeline into the playbooks and systems already in place. The Path to Full-Time For the right person, this engagement is designed to convert into a full-time VP of Sales & Marketing role with broader ownership: accountability for leadership of the marketing and sales teams.The fractional period serves as the proving ground for that mandate. Who You Are You have scaled a marketplace. You have worked within or alongside a major marketplace organization and bring a deep understanding of two-sided dynamics, including liquidity, cold-start challenges, balancing supply and demand growth, and the distinct requirements of buyer and seller funnels. You optimize and you build. You have measurably improved the performance of existing acquisition channels, and you have identified, tested, and stood up new ones; you know when to tune a channel and when to start a new one. You can attract both businesses and consumers. You have built B2B acquisition motions targeting business customers and B2C acquisition motions targeting consumers, and you understand that they require different strategies, channels, and messaging. You have grown SMB-focused sales teams. You have scaled sales teams that acquire small and mid-sized business customers directly relevant to our supply side, where the customer is an independent retailer and that experience positions you to grow into broader sales and marketing leadership as the role converts to full-time. You are fluent in modern discovery. You bring proven expertise in SEO and active, demonstrated experience in GEO and AEO, reflecting a clear understanding of where discovery is heading. You are a full-funnel, data-driven operator. You evaluate performance in terms of pipeline, conversion, CAC, LTV, and payback, and you are equally comfortable building a financial model and directing a campaign. You are a leader who can both advise and build. You can set strategy and guide an existing team in a fractional capacity, and step into full leadership, including hiring, developing, and retaining talent as the role converts. Requirements - 8+ years in sales, marketing, or demand generation, with at least 3 years in a senior leadership capacity. - Background in ecommerce, retail tech, or consumer marketplaces. - Direct experience at or with a major two-sided marketplace. - Proven track record optimizing existing acquisition channels and creating new ones, across both B2B and B2C (or B2B2C) audiences. - Demonstrated experience growing or scaling sales teams that acquire the SMB market. - Hands-on command of SEO and working fluency in GEO and AEO. - Strong product-led growth experience. - Fluency in modern sales and marketing tooling (HubSpot, Klayvio, attribution platforms, SEO/SEM tools) and a track record of ROI-based decisions on spend and headcount. - Availability for a fractional engagement with the intent and ability to convert to full-time.
