Software Engineer

Solen Software Group is an evergreen holding company that acquires and operates proven software businesses that have significant growth potential in a variety of vertical markets, enabling them to be market leaders in their niche industry. Solen owns several software companies in various market spaces: Human Resource Technology, Fleet Telematics, Asset Management, E-Health, Document Management, and other innovative software solutions in a variety of industries. Solen is backed by a group of advisors and investors that have built software businesses of material scale (10-100M in ARR) and advised many.

As an AI Software Engineer in our Brazil Developer CoE, you will contribute to building standardized code, tools, and best practices that make our portfolio companies faster, more reliable, and more capable. This is a Day 1 opportunity…Solen is building this from the ground up and it will continue to scale for decades.

This is an entry-level role with real responsibility. You will learn modern development practices while supporting code reviews, prototyping, and process improvements. You will ship code using AI that matters for real customers, across real businesses while developing your craft in a high-growth, high-learning environment.

• Write quality code leveraging AI to develop shared libraries, tools, and prototypes under the guidance of senior team members.
• Participate in code reviews, bug fixes, and refactoring efforts for CoE deliverables across Solen portfolio companies.
• Implement features and functionality using approved stacks including C#, JavaScript, TypeScript, Python, and others as needed.

• Attend workshops, contribute to internal tech talks, and help build documentation that raises the bar for the entire CoE.
• Assist in creating reusable assets such as templates, CI/CD pipelines, testing frameworks, and shared components that accelerate delivery.

• Work closely with the CoE team to meet service-level agreements (SLAs) for requests from Solen portfolio companies.
• Track and manage tasks in Jira or GitHub, report progress in daily standups, and stay aligned with team priorities.
• Support governance by following coding standards, security protocols, and compliance requirements across all work.

In this role, success looks like:

• Contributing meaningfully to 2+ Solen company projects within your first 4 months.
• Generating 30%+ of your code output using AI-assisted development tools—and using them thoughtfully to accelerate delivery without sacrificing quality.
• Becoming a subject-matter expert in 2–3 portfolio company development stacks within 6 months, so you can independently deliver work in those environments using AI.

You are curious, scrappy, and motivated to learn fast. You enjoy the challenge of jumping into unfamiliar codebases, understanding how things work, and making them better. You have shipped real software—whether for school, open-source, side projects, or professional work—and you are excited by the opportunity to work across multiple tech stacks, domains, and business problems.

You believe AI tools are a force multiplier for developers, and you have already experimented with tools like Cursor, GitHub Copilot, ChatGPT, or similar platforms to write, debug, or refactor code. You want to get better at software development in an environment that values speed, ownership, and continuous improvement.

• 2–4 years of software development experience (professional, academic, or personal projects welcome).
• Basic proficiency in at least one language: Java, Python, or JavaScript.
• Familiarity with Git, Agile basics, and any cloud platform (AWS, Azure, or GCP).

• Bachelor's degree in Computer Science, Software Engineering, or a related field (or equivalent practical experience).
• Fluent in Portuguese; conversational English for collaboration with global team members and stakeholders.
• Strong problem-solving mindset, eagerness to learn, and collaborative team-player attitude.

• Exposure to DevOps tools such as Docker, Jenkins, or GitHub Actions.
• Experience with databases such as PostgreSQL, MongoDB, or similar.
• Hands-on work with one or more of the following: Angular, TypeScript, React, .NET, C#, JavaScript, AWS, or Azure.
• Participation in hackathons, open-source contributions, or university capstone projects.

• Exposure to enterprise software projects across multiple vertical market software companies.
• Meaningful career growth in a scaling tech hub in Brazil, with clear pathways to mid-level and senior engineering roles.
• A team environment that values learning, experimentation, and doing hard, important work that compounds over time.

Our Solen-isms 

Our culture is grounded in a set of principles we call Solen-isms. These shape how we work, how we lead, and how we build companies. 

Will to Win 

Leaders pursue full potential and refuse mediocrity. They care deeply, keep score, and raise standards because what you tolerate is what you get. 

Candor 

We communicate with integrity, transparency, and respect in all conversations. 

Frugality 

Achieving more with less, focusing on quality, long-term value, and company-wide responsibility. 

Pioneering 

Leaders chase opportunity, not precedent. They think from first principles, challenge convention, and act without waiting for permission or perfect conditions. 

Mutual Elevation 

Committed to growth, elevating teams, developing future leaders, and removing barriers to mastery and joy. 

Learn-It-Alls 

Learn-it-alls, not know-it-alls, embracing failure as part of growth and progress. 

Figureitoutiveness 

Embracing challenges, fostering growth, and taking initiative. Leaders thrive on hard work and high failure tolerance. 

Openly Self-Critical 

“Rub your nose in your own mistakes.” – Charlie Munger.
 Leaders go first: they surface their misses early, ask for direct feedback, and turn game film into better decisions and better systems. 

Ownership Mindset 

We own the mission. We don't wait to be told. We lead, fix, and build as if it were ours. When problems arise, we run toward them, not away. 

Dialectical 

We pursue truth through structured disagreement. We test ideas from multiple angles, integrate the strongest points, and leave with clearer decisions. 

Benchmark to Best 

We seek out excellence. We measure ourselves against the best and adapt quickly, always looking for the edge that moves us forward. 

Disagree & Commit 

Leaders disagree openly and constructively, regardless of title or tenure, because truth is how we avoid bureaucracy and benchmark to best. 

Kaizen 

Kaizen is continuous improvement as a way of life. Leaders make hundreds of small upgrades that compound, turning lessons into standards and standards into durable systems.
