Hello everyone!
We’re looking for a hands-on QA Lead to manage quality practices for our project. This role combines people/process leadership with strong practical expertise in both Manual QA and Automation QA, with automation built using our Playwright-based (JS) framework.

Project Idea

The project was founded back in 2014 with the goal of connecting private and government universities/schools with regular people like we are. You have a variety of auditoriums, gyms, classrooms, and other venue options available for community use —
schedule facility uses and manage requests from the community all in one place.Just imagine that you’re a football player and you can rent a football field at Harvard to play with your friends. Amazing, right?

What exciting things is the product doing for the community?

The product is transforming the way public and private spaces are discovered, reserved, and used across communities — all online and accessible anywhere.

What is the team size and structure?

Our team consists of: 2 Front-End developers, 3 Back-End developers, 1 React-Native developer, 2 UI/UX Designers, 2 QA, 3 AQA, and PM.

How many stages of the interview are there?

— Interview with the Recruiter — up to 30 min.;

— Technical interview — up to 1.5 hours;

— Interview with the client — up to 1 hour.

Key Responsibilities:

• Own and drive the overall QA strategy across the project (manual and automation), defining quality standards, release readiness criteria, and continuous improvement initiatives aligned with product risk and delivery cadence.
• Work with a required daily overlap of ~6 hours with the client’s time zone; this typically means working until approximately 9 PM — 12 AM EET.
• Lead hands-on test planning and execution for features and epics, providing early feedback on requirements to improve clarity, testability, and quality.
• Maintain a hands-on balance between leadership and execution, with approximately 60% focused on QA leadership and strategy, and 40% dedicated to hands-on testing and automation.
• Ensure efficient, lightweight test documentation, strong regression coverage, and clear traceability between requirements, tests, and defects.
• Own, maintain, and evolve test automation using the Playwright-based JS framework, expanding reliable coverage for critical user flows.
• Proactively manage flaky tests, improve test stability, and ensure automation is trusted by the team.
• Partner closely with Engineering and Product teams to establish shared ownership of quality, run bug triage, align on defect severity and priorities, and support confident release decisions.
• Mentor QA and AQA engineers through coaching, reviews, and knowledge sharing; help define clear QA ownership within the team.
• Contribute to hiring, onboarding, and shaping QA best practices when needed.

Requirements:

Must have:

• 5+ years in Quality Assurance with a mix of manual and automated testing.
• Prior experience in a QA Lead role with clear ownership of QA processes within a team.
• Solid hands-on experience with test automation using Playwright framework.
• Strong understanding of test strategy, test planning, risk-based testing, and release readiness.
• Ability to mentor, coach, and review the work of other QA engineers.
• Strong communication skills and a proactive, ownership-driven mindset.
• Upper-Intermediate English or higher for effective communication and documentation.

Nice to Have:

• Experience with API testing (Postman and/or automated API tests).
• Basic knowledge of SQL and experience debugging web applications using browser developer tools.
• Experience with CI/CD integration (GitHub Actions, CircleCI, Jenkins).
• Familiarity with test reporting tools (Allure, HTML reports) and test management tools.
• Exposure to performance, accessibility, or security testing fundamentals.
• Prior experience building or heavily refactoring a test automation framework, including architecture decisions, patterns, and stability improvement.

What Success Looks Like (first 3-6 months):

• Clear QA operating model is in place: test strategy, quality gates, regression approach, and triage routine.
• Automated suite coverage increases for critical paths, and flakiness decreases with a stable CI signal.
• Fewer escaped defects and better predictability for releases.
• The team demonstrates stronger testing habits: better AC clarity, earlier risk identification, and consistent QA standards.

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.

About the Position

We are looking for an experienced professional to lead the Risk Analytics function and take responsibility for the performance of the loan portfolio, monitoring key risk metrics, and developing the company’s analytical processes.

Requirements

• Strong SQL skills and hands-on experience working with relational databases.
• Advanced proficiency in Google Sheets and Microsoft Excel (complex formulas, pivot tables, data analysis).
• Deep understanding of credit product economics.
• Experience managing teams and overseeing performance indicators.
• Ability to build transparent analytical and operational processes.

• Ability to translate business requirements into clear technical specifications for the IT team.

   

What We Offer
