We are building the next generation of our platform and investing heavily in scalability, reliability, automation, and AI as we grow toward processing millions of transactions per day.
This is a hands-on role for experienced full-stack engineers who combine strong technical leadership with a passion for building scalable systems and helping evolve a growing platform into one that can process millions of transactions every day. While much of the work focuses on backend architecture and distributed systems, you should be comfortable contributing across the entire stack.

What You’ll Do:

• Design and build end-to-end systems across backend and frontend
• Build and evolve scalable distributed systems that support high-volume transaction processing
• Help drive the evolution of our event-driven architecture, improving reliability, performance, and operational efficiency
• Improve system scalability, observability, resiliency, and fault tolerance
• Work on distributed workflows, asynchronous processing, and large-scale data pipelines
• Contribute to architecture discussions, technical design reviews, and engineering best practices
• Collaborate closely with engineering, product, customer success, and leadership teams on strategic initiatives
• Build and maintain cloud-native infrastructure and deployment workflows
• Evaluate and implement AI-powered capabilities, automations, and agent-driven workflows

Requirements:

• 8+ years of software engineering experience
• Strong full-stack capabilities (backend + frontend)
• Expert-level Node.js and TypeScript experience
• Strong experience with modern frontend frameworks (React preferred)
• Proven experience building and scaling production systems
• Strong understanding of distributed systems and event-driven architectures
• Experience working with AWS and cloud-native systems
• Ability to work independently and take full ownership
• Strong problem-solving and execution skills

Nice-to-Have

• Experience with AWS Serverless technologies (Lambda, EventBridge, SQS, Step Functions)
• Experience with Infrastructure as Code
• Experience integrating AI agents or LLM-powered workflows into production systems
• Experience in B2B SaaS environments
• Experience working in fast-paced startup environments

Why Join Monto?

• Help scale a platform processing millions of transactions
• Work with modern technologies, including TypeScript, AWS Serverless, event-driven architectures, and AI-powered systems
• Influence key architectural decisions with company-wide impact
• Join a highly collaborative team with significant ownership and autonomy
• Solve challenging technical problems with real-world scale and complexity

About Us
Monto brings unprecedented simplicity to B2B payments. Our AI agents take suppliers from portal to payment across 500+ AP portals like Ariba and Coupa, helping businesses get paid on time, every time, from their biggest customers. Trusted by global companies like Miro and Shutterstock, we’re scaling fast, and we want you to join us on this exciting journey.

Job Description
Monto’s product is built on AI agents, and our go-to-market runs the same way. We use agents to find, research, and engage the right companies, and we’re expanding that across outbound and inbound. We’re looking for a GTM Engineer to build that engine and run it. Most of your time goes into building: new agents and workflows, better versions of the ones we have, and decisions on where agents lead and where a person adds more value. The rest goes into using what you build, including owning key conversations with finance leaders that turn into pipeline.

What You’ll Do

• Run and expand our agent-driven go-to-market motion across outbound and inbound, taking it into new segments and use cases
• Build AI agents and workflows that find target accounts, the right decision-makers, and buying signals, and get inbound leads to the right person fast
• Turn AI research into personalized outreach to finance leaders across email, LinkedIn, and phone
• Handle replies and objections, qualify leads, and book high-value meetings that create qualified pipeline for the sales team
• Partner with sales and marketing on the ICP, messaging, and campaigns, and build tools they actually use
• Evaluate agent output, refine prompts and data sources, and keep quality high as volume grows
• Measure every stage, from first signal to closed deal, and use the results to improve the system
• Own the GTM stack, including Clay, LLMs, HubSpot, and email deliverability, and keep CRM data clean

Qualifications

• 2+ years in SDR/BDR, growth, RevOps, or sales and marketing ops roles, with a track record of generating pipeline
• Hands-on experience building AI agents or automated GTM workflows that last, with examples and numbers you can walk us through
• Strong Clay (or similar) skills, and working knowledge of HubSpot
• Practical experience using LLMs in workflows: writing prompts, testing output for accuracy, and knowing when a step needs AI and when it needs simple logic
• A systems thinker who is comfortable with data, testing, and iteration
• Confident in conversations with senior finance decision-makers
• Native or near-native English with excellent written and verbal communication
• Experience selling to the US market and flexibility to work partial US hours
• Experience in fintech or SaaS is a plus

• Lead executive business reviews that connect Monto’s performance to measurable business outcomes such as automation rates, DSO, time-to-cash, operational efficiency, and time saved
• Own and execute account growth strategies, proactively identifying and closing expansion opportunities across new workflows, business entities, buyers, and Monto capabilities
• Own renewal strategy and execution, proactively identifying risk, building executive alignment, demonstrating ROI, and driving successful commercial outcomes
• Build a deep understanding of each customer’s financial operations and identify new problems Monto and AI can solve
• Act as the strategic owner during customer challenges, mobilizing the right internal teams while keeping the conversation focused on outcomes and the long-term partnership

Qualifications

• Strong cross-functional collaborator who gets things done across teams
• Comfortable operating with ambiguity, building processes, and taking ownership in a fast-moving startup environment
• Excellent written and verbal communication in English
