Lead Software Engineer

About Solen Software Group Solen Software Group is an evergreen holding company that acquires and operates proven software businesses with significant growth potential across a variety of vertical markets, enabling them to become category leaders in their niche. We own and operate software companies in Human Resource Technology, Fleet Telematics, Asset Management, E-Health, Document Management, and other vertical SaaS markets, backed by advisors and investors who have built and scaled software businesses from 10–100M in ARR.

We compound for decades, not quarters, and we are building a global network of centers of excellence that raise the bar for how vertical market software is built, operated, and scaled.

About the Role At Solen, it's Day 1 of a decades-long journey in Brazil. As Technical Lead for our Brazil Developer CoE, you will be the hands-on engineering leader who turns that vision into code, systems, and a high-performing team.

You will architect and operate a shared engineering capability that modernizes legacy systems, scales our portfolio's development capacity, and sets the technical standards for how Solen builds software across its companies. You'll balance strategy and execution: owning the roadmap, writing code on high-impact work, and helping portfolio company teams ship reliably and at quality

What You'll Do Technical Strategy & Architecture Own and evolve the CoE technical roadmap, including stack standardization that creates the most leverage across Solen companies (for example C#, JavaScript/TypeScript, Python). Lead architecture reviews, design patterns, and proof-of-concepts for cloud-native solutions on AWS/Azure/GCP, including containers, Kubernetes, and serverless. Drive technical debt reduction and modernization programs (for example monolith-to-microservices migrations, API-first initiatives, AI/ML integration where it is genuinely accretive).

Engineering Operations & Delivery Design and operate CI/CD pipelines (for example GitHub Actions) that support frequent, reliable deployments across multiple codebases. Run a CoE “service catalog” for portfolio companies: code reviews, prototyping, performance optimization, security scanning, and developer tooling. Implement and track engineering metrics (code churn, test coverage targets, vulnerability density) to create a transparent, data-driven view of delivery health.

Standards, Platforms & Enablement Define and enforce coding standards, API guidelines (REST/GraphQL, OpenAPI), and security best practices. Build and maintain shared assets: reusable libraries, Docker images, Helm charts, and internal developer platform components that make our engineers faster and safer by default. Lead workshops and enablement sessions on topics such as event-driven architecture, reactive programming, observability, and GenAI-assisted development.

Team Leadership & Talent Recruit, grow, and lead a 10-to-20-person engineering team in Brazil across full-stack, DevOps, AI, and platform engineering skill sets. Lead by example: pair-program, perform high-quality code reviews, and own critical paths on key deliveries. Foster a culture of blameless postmortems that share patterns and raise the bar.

Governance & Stakeholder Partnership Partner closely with global architects, product leaders, and security teams to balance innovation with compliance and risk management. Report technical KPIs and CoE impact to the Solen executive team via dashboards and concise documentation. Optimize cost and capacity through smart resource allocation, re-use of shared components, and thoughtful use of open source and cloud-native services.

Outcomes You Own In this role, success looks like:

A high-performing Brazil CoE team of 15+ engineers delivering reliably for multiple Solen portfolio companies. 10+ meaningful Solen/OpCo projects successfully delivered, with portfolio leaders viewing the CoE as their preferred partner for complex engineering work. Clearly defined and repeatable CoE operating processes that can be replicated in other geographies. A reputation as the trusted technical lead that portfolio companies seek out for architecture, modernization, and “hard” engineering problems.

About You You are a

builder

who is as comfortable at the whiteboard as you are in the codebase. You enjoy turning ambiguity into a roadmap, and a roadmap into shipped software and a stronger team.

You thrive in environments where standards are being created, and you are motivated by the opportunity to shape a flagship engineering center in Brazil that will compound for years.

Technical Expertise 10+ years in software engineering, with at least 5 years in senior/lead roles managing distributed or multi-team environments.

Deep experience with modern backend and frontend stacks (for example Java 17+/Spring Boot 3, Python 3.11+, React or Vue) and relational / NoSQL databases (PostgreSQL, MongoDB, Cassandra).

Hands-on experience with cloud platforms (AWS strongly preferred, Azure/GCP welcome), containers (Docker, Kubernetes), and DevOps automation. Proven track record in performance tuning, distributed systems, observability, and running production systems at meaningful scale.

Leadership & Domain Demonstrated success building or scaling engineering centers, ideally in Brazil/LATAM, for B2B or enterprise software businesses. Strong grounding in Agile and DevOps at scale; certifications such as AWS Solutions Architect are a plus but not required. Experience partnering with non-technical stakeholders (Founders, General Managers, Product) and translating business constraints into pragmatic technical decisions.

Communication & Mindset Fluent in Portuguese and English, with the ability to influence and align across a matrixed, global organization. Data-driven and experimental, using metrics, retrospectives, and structured experiments to drive continuous improvement. A champion of AI in software development, with hands-on experience leading AI-related projects or integrating AI into developer workflows considered a plus.

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.
