From Testing to Full‑Stack Delivery: Inside SEQIS with Alexander Weichselberger – Agile, Generalist, Customer‑Centric

Context: What we learned from Alexander Weichselberger of SEQIS Group GmbH

SEQIS has long been synonymous with quality assurance, analysis, and project management in Austria’s IT scene. In our session with Alexander Weichselberger, Managing Partner of SEQIS Group GmbH, one motive stood out: “we simply want to do cool IT projects.” To win the trust and scale required for critical work, SEQIS built a team‑based organization instead of relying on lone‑wolf heroics.

Today, SEQIS also runs a dedicated development arm. The focus: full‑stack engineering with generalists who understand the entire value chain from requirements to deployment—while still allowing those who prefer specialization to stay focused. That duality isn’t a contradiction; it’s how the team actually operates.

Below is our DevJobs.at editorial recap of how SEQIS defines modern engineering culture, how the team is structured, how hiring and onboarding work, and why the environment appeals to engineers who like to own the full picture.

Why SEQIS was founded: From lone expert to organization

Alexander’s original motivation is refreshingly direct:

The reality in critical projects, however, is that solo freelancers rarely get entrusted with the most interesting work—and they don’t scale. SEQIS was founded to:

• earn trust for larger, more critical projects,
• orchestrate delivery across multiple disciplines, and
• operate with scalability and reliability.

This baseline—professionalism over luck—still guides everything SEQIS does.

From software testing to delivery organization: Portfolio evolution in stages

SEQIS “originally started with software testing,” then expanded to IT analysis and later to project management. The company is used to broadening its scope—and managing that expansion responsibly. Building on that, SEQIS established a dedicated development unit “last year”: the “Radsfahrt-CEO” area as an autonomous track for software development services.

Agility here is practice, not buzzword. SEQIS shipped products as early as 2001—then using Feature‑Driven Development (FDD). Today, the team leans on familiar standards such as Scrum or Kanban, aligning with what customers want.

The “Radsfahrt-CEO” development team: small, focused, scalable

The “Radsfahrt-CEO” team currently consists of six people. Importantly, the team is embedded in the wider SEQIS organization: “If we need to scale, we can rely on the entire SEQIS background in the company and scale accordingly.”

This coupling brings two advantages:

• the compact, focused delivery team can move fast, and
• when necessary, SEQIS can draw on the broader company for capacity, know‑how, and structure.

For candidates, this means a setup that enables speed and closeness—without losing the stability and quality assurance of a mature organization.

Generalists—with real respect for specialization

SEQIS prefers to hire generalists. It’s a deliberate choice because it scales well for clients and the team—and it keeps the work varied.

At the same time, individual preference matters: If someone “is firmly focused on frontend,” SEQIS makes it work. For tech talent, this creates space to be T‑shaped or to go deep—without having to leave the culture to do so.

Looking beyond the code as a core skill

SEQIS cultivates a “look beyond the rim of the plate.” That means developers don’t just code; they understand the full value chain: requirements, testing, and project management. This perspective is deliberately nurtured—especially during onboarding.

How SEQIS executes: Agile, iterative, customer‑close

SEQIS operates in four modes of delivery (details below). The common denominator is close collaboration with customers, especially when running agile projects from SEQIS’s office. Tight feedback loops, clear decisions, visible output.

This contact strengthens motivation. Alexander notes that developers value direct client feedback much more than he once assumed:

Stacks and application types: Full‑stack by default—“you name it”

SEQIS works across mainstream languages and application types:

• JavaScript, Java, .NET, PHP, Ruby—“you name it”
• Application types: Progressive Web Apps, desktop apps, native, mobile

The default trajectory is “toward full‑stack.” In client projects, the stack isn’t preordained; the team evaluates the setup—and if it’s cool, they dive in and deliver. Pragmatism over tool dogma.

DevOps and quality culture: Continuous deployment and resource discipline

SEQIS wants developers to know the “complete value chain.” That includes continuous deployment, quality assurance around each check‑in, and attention to resource usage.

A standout is the insistence on efficiency: more bandwidth (4G, 5G) is no excuse for bloated apps. Alexander puts it vividly:

He also references an anecdote from mobile connectivity:

Regardless of the exact figure, the point stands: resources aren’t free—user time, bandwidth, energy, cloud costs. Good solutions are not only correct; they’re well‑sized and keep complexity in check.

Four lines of business: Advisory, co‑development, full project delivery, own products

SEQIS shows up in four market‑facing ways:

1. Advisory: helping customers figure out “how to properly approach software development.”
2. Co‑development: “we develop and program for the customer in their project.”
3. Full project delivery: “we want to—and we do—deliver complete IT projects as software solutions.” This is the main focus, from requirements to a running solution with tight customer exchange.
4. Own products: currently two in the pipeline— a requirements engineering plugin for Jira and a time tracking solution for IT.

The product work targets a pragmatic middle ground between “overblown and complex” and “very stripped‑down.” For engineers, this yields variety between client delivery and product development—and exposure to both short‑term output and long‑term software stewardship.

Hiring: fast, transparent, with a genuine culture handshake

SEQIS sources via multiple channels. A key one: “We rely on Dev‑Jobs. We’ve been using it consistently for two years.” The company also taps its network and other providers.

In the selection process, two things matter most:

• Team fit: “whether they fit into our team”
• Passion: “whether they share our passion for what we do”

Crucially, SEQIS also introduces itself in the interview. Candidates should know “how we tick and what matters to us.” Decisions usually come quickly—good news for applicants who value clarity.

Onboarding via bootcamp: Testing, requirements, PM—plus tools and ways of working

New hires start with a bootcamp. It covers:

• The company, mission, and “how we tick”
• Internal tools
• Knowledge transfer across the value chain: “how proper software testing works,” “how IT requirements engineering works,” and “what to consider in project management”

The goal isn’t to turn developers into consultants; it’s to help them understand the broader context. The effect: “excellent programmers, not just good ones,” because they think beyond their immediate code.

Assignment flow: internal first, then customer—powered by live feedback

After the bootcamp, engineers rotate through the four SEQIS areas. The typical start involves internal projects or work on SEQIS’s own products. Later, engineers “go out to the customer,” benefitting from the motivation boost of immediate feedback.

Why SEQIS is compelling for tech talent

SEQIS is built for developers who enjoy end‑to‑end responsibility and variety. The combination of delivery modes, customer proximity, and deliberate onboarding creates an environment that delivers on multiple fronts:

• Breadth and depth: work as a generalist—or focus deeply if that’s your path.
• Agility with history: from early FDD to Scrum/Kanban today—methods applied pragmatically, not dogmatically.
• Full‑stack mindset: from PWA to mobile, with stacks chosen for outcomes.
• Product and project: alternating rhythms and learning cycles.
• Customer closeness: direct exchange, visible impact, fast feedback.
• Quality and DevOps: continuous deployment and disciplined check‑ins.
• Resource discipline: efficient code and delivery as a conscious value.
• Fast, fair hiring: emphasis on team fit and passion, with quick decisions.

For many engineers, that’s the ideal blend of craft, responsibility, and impact.

Clear signals for applicants

From Alexander’s comments, several expectations emerge. Engineers who thrive at SEQIS typically bring:

• Motivation for “cool IT projects”—work with ambition and impact.
• Willingness to look beyond code: testing, requirements, PM, delivery.
• Comfort with agile collaboration and real customer contact.
• Openness to multiple stacks (JavaScript, Java, .NET, PHP, Ruby) and app types (PWA, desktop, native, mobile).
• Ownership of the full value chain—including quality assurance and deployment.
• Efficiency mindset: lean code, sensible payloads, pragmatic architecture.
• Team spirit and passion—both are explicitly assessed.

Trend view: Orchestration over net new—taming complexity

Alexander names a decisive industry trend:

That’s a precise description of where modern engineering is headed: integrate wisely, don’t stack blindly. Solutions stay stable only if complexity is deliberately constrained. SEQIS anchors that stance in its organization, methods, and hiring.

Takeaway: SEQIS’s offer to engineers

Represented by Alexander Weichselberger (Managing Partner of SEQIS Group GmbH), SEQIS presents a consistent picture:

• Origin: quality‑driven delivery is core DNA.
• Build‑out: from testing and analysis to project management, then to a dedicated development unit (“Radsfahrt-CEO”).
• Team: compact, scalable, generalist—while respecting specialization.
• Work: agile, customer‑close, focused on whole projects and tangible outcomes.
• Culture: bootcamp onboarding, end‑to‑end understanding, DevOps, resource discipline.
• Market: four models—advisory, co‑development, full delivery, own products.
• Hiring: fast, open, centered on passion and team fit.

If you’re an engineer who wants to build solutions—not just ship features—this is an environment with a clear signature: think like a generalist, deliver pragmatically, secure quality, and create real impact together with the customer.
