Most engineers need a headshot roughly once every three years, usually the week they start job hunting or get asked for a conference bio. It is nobody's favourite task, and the corporate-portrait convention feels wrong for the field.
The tech convention is genuinely different
Engineering culture reads a formal suit-and-tie portrait as slightly off — not unprofessional, but out of step. The look that fits is deliberately understated: a solid tee, henley, or open collar, natural light, minimal styling.
This is one of the few professions where trying too hard is the bigger risk.
What to aim for
- Solid colours, no busy patterns. Small avatars destroy detail.
- Soft natural light, not studio-hard. The over-lit corporate look is the giveaway.
- Neutral or softly blurred background. Avoid the literal server-room or code-on-screen backdrop.
- Square crop. GitHub, Slack, and most internal directories render circular avatars.
Where it actually gets used
Your LinkedIn photo matters during a job search, but day to day the photo people see most is your Slack and GitHub avatar — displayed at maybe 40 pixels. Anything busy turns to mush at that size, which is the practical argument for a tight crop and a plain background.
Conference and meetup speaker bios are the other common use, and those often want a higher-resolution version than your avatar.
One selfie, several framings
The tech pack generates the understated engineering look across avatar-sized square crops and the larger framing speaker bios ask for. If you are weighing tools, the best free AI headshot generators roundup covers what you get without paying.
