About Altum

Altum Software is a technology company building AI-powered infrastructure for sales and business automation. We design and develop internal systems that replace manual workflows with autonomous AI agents — from lead qualification pipelines to customer communication layers.

We're a small, senior team that moves fast and builds things that actually work in production. No corporate overhead, no pointless meetings — just interesting problems and real ownership over what you ship.
 

The Role

We're looking for a Software Engineer to join the team building our AI automation infrastructure. You'll work on systems that operate at scale — managing concurrent sessions, orchestrating background jobs, integrating LLMs into real-world workflows, and making sure everything stays stable when it matters.

This is a hands-on engineering role with real architectural responsibility. You'll work directly with the founding team and have full visibility into product decisions.
 

What You'll Be Working On

• Building AI SDR systems — autonomous agents that manage communication pipelines, qualify leads, and move them through the funnel without manual intervention
• Developing browser automation layers that interact with web platforms on behalf of AI agents — handling sessions, actions, and anti-detection logic at scale
• Integrating LLMs (Claude API) for real-time message classification, context-aware response generation, and conversation management across hundreds of active threads simultaneously
• Building the job orchestration layer — queues, background workers, concurrency handling — that keeps everything running reliably at scale
• Connecting the system with external tools: CRM, calendar booking, messaging platforms, alert systems
• Designing internal AI agents that handle repetitive customer-facing workflows autonomously, escalating to humans only when needed

Requirements

• 2+ years of commercial experience in backend or fullstack development
• Strong understanding of system design — queues, background jobs, concurrency, failure handling
• Experience working with relational databases (PostgreSQL or similar)
• Comfortable integrating third-party APIs and navigating unfamiliar documentation quickly
• Systematic thinker — you see how components compose into a reliable whole
• Genuine curiosity about AI tooling — you follow what's happening in the space and like to experiment

Nice to Have

• Experience with Playwright, Puppeteer, or any browser automation framework
• Familiarity with anti-detect browsers or browser fingerprinting concepts
• Prior experience working with LLM APIs (Claude, OpenAI, or similar)
• Understanding of bot detection mechanisms and mitigation strategies
• Experience with Redis / BullMQ or similar job queue systems

What We're Really Looking For

Technical skill matters, but it's not the whole picture. We're looking for someone who picks things up fast, takes ownership without being asked, and genuinely enjoys working at the intersection of AI and automation. You don't need to have done exactly this before — but you should be the kind of engineer who looks at a complex system and wants to understand how it works end to end.

If you've never built browser automation before but the problem space excites you — reach out anyway.
 

What We Offer

• Fully remote, async-friendly environment
• Flexible schedule — outcomes over hours
• Direct collaboration with the founding team
• Real ownership over technical decisions
• Long-term engagement for the right person

Fit4Me is looking for a Head of Payments who will drive revenue growth through payment infrastructure, billing logic, and optimization of the payment experience.

In this role, you will define the payment strategy, lead the development of the billing system, and make decisions that directly impact revenue, retention, and scalable growth across Tier 1–2 markets.
This role is for a leader who combines strategic thinking with a hands-on approach: someone who both defines the direction and drives execution.

 

This role is a great fit if you:

• Want to own the payments domain and drive revenue, not just manage processes.

• Think in terms of growth and understand how payments impact conversion, LTV, and product scalability.

• Can prioritize and cut through noise, making decisions where the balance between approval, cost, and risk delivers the best business outcome.

• Feel comfortable in a player-coach role: shaping strategy while staying hands-on with key initiatives.

Impact Areas

1. Payment Strategy & Revenue Growth
• Define the payment strategy as part of the overall growth approach, driving impact on revenue, LTV, and product scalability.
• Own key payment metrics (payment success rate, renewal rate, recovery rate) and continuously improve them through data-driven solutions.
• Build and optimize billing logic (retry, dunning, renewal flows) to maximize conversion and user retention.
• Prioritize initiatives by balancing conversion, cost, and risk based on business needs and growth stage.
• Optimize the payment experience in close collaboration with the Product team.
2. Payment Infrastructure & Scaling
• Build and scale the payment infrastructure: multi-PSP setup, routing, orchestration.
• Select and launch new payment providers, payment methods, and markets (Tier 1/Tier 2).
• Ensure stable payment processing while scaling traffic and revenue.
3. Cost & Efficiency Management
• Optimize payment processing costs (PSP fees, routing, balancing conversion vs cost).
• Lead negotiations with payment providers and improve partnership terms.
• Own payment margin as part of the product’s unit economics.
4. Risk & Stability Control
• Monitor chargeback rate, fraud, and other risk metrics as key constraints for growth.
• Build approaches that enable scaling without exceeding risk benchmarks.
5. Team Leadership & Execution
• Lead Payment Operations and develop the team.
• Set priorities and ensure the right balance between strategic initiatives and operational execution.
• Work directly with the CEO, Product, and Marketing teams to drive growth initiatives.


 

What we expect from you

• 4–6+ years in payments / billing / subscription-based products, with direct impact on payment conversion, retention, or revenue.

• Experience working with high-volume payments ($3–5M+ monthly) and understanding how scale affects performance metrics.

• Building end-to-end payment flows: from payment methods (cards, PayPal, Apple Pay, Google Pay) that impact conversion, to subscription billing (recurring payments, retry / dunning logic, renewal flows, and declined payment handling).

• Strong understanding of unit economics (LTV, CAC, margins) and the role of payments within it, combined with the ability to analyze metrics, form hypotheses, and make decisions that impact revenue and scalability.

• Experience working with Tier 1 / Tier 2 markets and localizing payment methods.

• Building and optimizing payment infrastructure: PSPs (Stripe, Adyen, Braintree), routing, integrations, and launching new payment methods.

• Experience leading a payment function or team, building processes, and setting priorities.

• Upper-Intermediate (B2+) English for working with providers, negotiations, and optimizing partnership terms.

What success looks like in this role

• Payment infrastructure runs reliably at scale: high approval rates, controlled risk levels, and no critical revenue loss.

• Payments become a growth driver: increased payment conversion, improved renewal rates, and higher recovery of failed payments.

• A clear and effective payment strategy is in place: defined priorities, a strong balance between cost / conversion / risk, and a roadmap that supports product scaling.

• Payment processing costs are optimized without compromising performance: improved provider terms and efficient routing setup.

• Payment Operations runs as a well-structured system: stable processes, no operational bottlenecks, allowing you to focus on scaling and developing the function.
