Data Science vs Software Engineering — Which Will Grow Faster after 2025?


Who wins after 2025 — Data Science or Software Engineering? Detailed, beginner-friendly analysis of job growth, salaries, AI impact, skills, roadmaps, and how to pick the best career path.

⭐⭐⭐⭐⭐

  • Data Science is projected to grow faster percentage-wise than software engineering through the 2020s as businesses invest heavily in analytics and AI tooling.
  • Software Engineering will still produce far more absolute job openings and remain the backbone of product and infrastructure work; many software roles will evolve (AI-enabled dev tools, platform/infra roles).
  • AI is the wild card: it’s creating high-growth, high-pay roles (ML engineers, AI product engineers, prompt engineering) that sit between the two disciplines — and it impacts both.
  • Bottom line: If you want faster growth & novelty, lean Data Science/AI. If you want large demand + many paths + stable pipeline, lean Software Engineering. Best answer: learn both enough to cooperate — that’s where the market is moving.

1. Mmmm…💭What do we mean by “Data Science” and “Software Engineering”🤔?

  • Data Science = extracting insights from data: cleaning, exploring, building models (statistics, ML), communicating results. Think: analysis, experimentation, modelling, dashboards.
  • Software Engineering = designing, coding, testing, and maintaining software systems: apps, APIs, backend, frontend, mobile, cloud infra. Think: building production systems that people actually use.

They overlap a lot — data engineers, MLOps, ML engineers, and full-stack engineers often sit in both camps. Consider them cousins, not sworn enemies.

2. The big-picture growth numbers

  • The U.S. Bureau of Labor Statistics projects data scientists to grow ~34% from 2024 to 2034 — much faster than average. That’s huge.
  • The same BLS release projects software developers, QA analysts, and testers to grow ~15% from 2024 to 2034 — also strong, but roughly half the percentage growth of data science. Importantly, the software group translates to a much larger number of annual openings because the base is bigger.

So — percentage growth favors Data Science, but absolute job volume and breadth favor Software Engineering. (EG: a 15% slice of a larger pie can be more slices in total.)

3. Why does data science show higher percentage growth?

  1. More data, more questions. Every organization is collecting more data and needs people who can analyze it, build models, and measure outcomes.
  2. AI/ML productization. Businesses want to convert ML prototypes into products (personalization, fraud detection, forecasting), so demand for data-savvy people spikes.
  3. New job types. Roles like ML engineer, MLOps specialist, and data product manager multiply the visible “data” headcount.

4. Why software engineering remains massively important

  • Software is the production engine that makes models useful: APIs, scalability, reliability, security, UX. The world still needs engineers to build and maintain systems.
  • The volume of software (mobile apps, cloud services, embedded systems, IoT, fintech, gaming) creates steady demand across industries — not just tech startups.
  • Even with AI coding assistants, complex system design, debugging, and team collaboration remain human-centric skills.

Short intuition: data scientists ask what and why; software engineers build how.

5.how generative AI changes both fields

  • AI job listings — especially roles explicitly tied to AI — surged in recent years. Companies are hiring for ML specialists, AI product engineers, and platform roles.
  • Big companies are paying premiums for AI talent and investing in internal AI platforms. This raises compensation and demand for people who can bridge modelling + production.
  • AI augments many jobs (auto-completion for code, auto-analysis for data), which increases productivity but also changes required skill sets (e.g., MLOps, prompt engineering, evaluation metrics).

Net effect: AI increases demand for both good data scientists and experienced software engineers — especially those who can integrate AI safely and responsibly.

6. Salaries & compensation — what to expect

  • Both fields have attractive pay, but top AI/data roles in major tech companies have particularly high packages lately. At the same time, experienced software engineers (esp. systems, infra, ML infra, security) command premium pay.
  • Geography, company size, and domain (finance, health, defence) matter more for pay than the job title itself.

7. Hiring market signals: demand, layoffs, and hiring freezes

  • 2023–2024 saw big hires then corrections; 2025 shows a more selective market but AI roles remain resilient. Some software roles saw short-term dips in listings post-hiring-boom, but long-run demand is still positive.
  • That means junior candidates may face more competition in some markets; niche skills (ML infra, cloud, security) help cut through the noise.

8. How automation/AI changes the day-to-day in each job

  • Data Science: More auto-feature tools and AutoML — but business context, causal thinking, and productionizing models still require human judgment.
  • Software Engineering: AI can write boilerplate and tests, but system architecture, distributed systems debugging, and product tradeoffs stay human-led.

Automation makes both fields more productive — and raises the value of higher-level skills (design, evaluation, domain expertise).

9. After 2025 where the most growth and opportunity will be?

  • AI / ML product roles: ML engineers, MLOps engineers, AI platform engineers. (Cross of data + software.)
  • Data roles in regulated industries: healthcare, finance, biotech — demand for domain-savvy data people.
  • Cloud & distributed systems: as AI models become bigger, infra + optimization + cost-control roles scale.
  • Edge & embedded software: IoT and on-device ML open software engineering niches that won’t be easily automated.

10. How to choose: a practical checklist

Answer these to pick a path:

  1. Do you like math/statistics & storytelling with data? → Lean Data Science.
  2. Do you like building products, architecture, or low-level systems? → Lean Software Engineering.
  3. Do you enjoy both? → Aim for MLOps, ML engineering, full-stack ML, or data engineering (best of both worlds).
  4. Want fastest percentage growth & novelty? → Data Science/AI specializations.
  5. Want broader hiring market & many career ladders? → Software Engineering.

11. Roadmap: skills to learn (zero-to-Job)

Below are two compact roadmaps (beginner-friendly). Time estimates depend on time commitment.

Data Scientist Roadmap (beginner → hireable)

  • Foundations: Python, basic statistics, SQL, data cleaning.
  • Visualization: Matplotlib/Plotly/edashboards, storytelling.
  • Modeling: Supervised learning, logistic/regression, tree-based models (XGBoost), evaluation metrics.
  • ML tools: Scikit-learn, PyTorch or TensorFlow (basic).
  • Production & infra: SQL + data pipelines, Docker basics, introduction to MLOps (model deployment).
  • Portfolio: 2–3 end-to-end projects with code + short blog posts (notebooks + deployed app).
  • Suggested extras: domain knowledge (finance/health) and soft skills (communication).

Software Engineer Roadmap (beginner → hireable)

  • Foundations: One language well (Python/Java/JS/C#), data structures & algorithms (basics).
  • Web basics: HTML/CSS/JS for frontend OR backend (APIs with Node/Express, Django/Flask).
  • Databases: SQL + NoSQL fundamentals.
  • System design basics: REST, auth, caching, scaling, testing.
  • DevOps basics: Git, CI/CD, Docker, cloud intro (AWS/GCP/Azure).
  • Portfolio: 2–3 production-ish projects (hosted on cloud/GitHub + README).
  • Suggested extras: distributed systems, security, performance tuning.

12. Where to invest your learning time (best ROI)

  • If you want the higher growth curve fast: prioritize statistics + ML basics + SQL + Python + a deployed project.
  • If you want resilient demand: invest in software engineering fundamentals + cloud + system design + testing.
  • If you want to maximize hiring options: do both basics: data fundamentals plus software engineering production skills (MLOps!) — this combo is golden.

13. FAQs (short, SEO-friendly)

Q: Will software engineers lose jobs to AI?
A: AI can automate boilerplate, but not system design, product thinking, and complex debugging. Expect role evolution, not extinction.

Q: Is data science saturated?
A: It’s more competitive than before, but BLS projects strong growth (so more jobs will exist). Differentiation via domain expertise and production skills matters.

Q: Which pays more — software or data science?
A: Both can pay very well. AI-specialist roles and senior SW engineers at top firms often lead compensation lists. Geography and company matter a lot.

Q: Should I learn ML or web dev first?
A: If you want immediate product roles, web/dev. If you love data, start ML foundations and SQL. Both are useful.

14. Region & industry differences

  • U.S. & Western Europe: High pay, many AI roles, strong demand for ML infra. BLS projections cited earlier are U.S.-centric but indicative.
  • India & APAC: Fast growth in data roles (fintech, e-commerce, healthtech). Cost-sensitive companies hire more junior/full-stack roles but also invest in AI centers.
  • Regulated industries (health, finance): High demand for data scientists who understand compliance and domain-specific modelling.

15. The smartest career play

  • Short term (first 1–2 years): Learn software engineering fundamentals + SQL + one data/ML project. This gives employability and options.
  • Medium term (2–5 years): Specialize: either become an ML engineer/MLOps (bridge role) or pick a deep software area (systems, security, infra).
  • Why this works: You capture the high-growth aspects of data science while keeping the broad employability of software engineering. Employers love people who can ship models into production.
